Product overview & purpose

Selleys Auto Fix Marine Sealant is a professional-grade silicone sealant built for marine environments (SELLEYS_AUTO_FIX_MARINE_SEALANT-AUS_GHS.pdf). This 75g cartridge uses moisture-curing silicone chemistry that holds up against saltwater, temperature swings, and constant moisture — the conditions that separate a reliable sealant from one that fails.

The product carries Australian product codes 9300697107084 and 100118, with corresponding barcodes 9300697107084 and 9300697124845 (SELLEYS_AUTO_FIX_MARINE_SEALANT-AUS_GHS.pdf). It handles hull-to-deck joints, porthole sealing, below-waterline repairs, and general weatherproofing across the full range of boat maintenance work. The marine-specific formulation is built for conditions where conventional sealants give out — prolonged water immersion and relentless UV exposure.

Whether you're a professional marine technician or a boat owner doing your own maintenance, knowing this sealant's technical profile means you get the job done right the first time. This guide covers technical detail, safety protocols, and application guidance drawn directly from the manufacturer's safety and technical documentation.

Chemistry & composition

Selleys Auto Fix Marine Sealant uses a multi-component silicone chemistry with targeted functional additives that drive its curing performance.

The primary crosslinking agent is 2-Butanone, O,O',O"-(methylsilylidyne)trioxime (CAS 22984-54-9), present at 1–10% w/w (SELLEYS_AUTO_FIX_MARINE_SEALANT-AUS_GHS.pdf). This oxime crosslinker starts the moisture-cure reaction that converts liquid sealant into a tough, flexible elastomeric solid when it contacts atmospheric moisture. The concentration range confirms this component drives the primary curing reaction.

A secondary crosslinker, 2-Butanone, O,O',O"-(ethenylsilylidyne)trioxime (CAS 2224-33-1), is present at less than 1% w/w (SELLEYS_AUTO_FIX_MARINE_SEALANT-AUS_GHS.pdf). This vinyl-functional variant adjusts crosslink density and contributes to adhesion strength and flexibility in the cured matrix.

The formulation includes Cyclotetrasiloxane, octamethyl- (CAS 556-67-2) at less than 1% w/w (SELLEYS_AUTO_FIX_MARINE_SEALANT-AUS_GHS.pdf). This cyclic siloxane acts as a processing aid and rheology modifier, giving the sealant smooth, consistent flow from the cartridge.

For adhesion, the chemistry incorporates 1,2-Ethanediamine, N-[3-(trimethoxysilyl)propyl]- (CAS 1760-24-3) at less than 1% w/w (SELLEYS_AUTO_FIX_MARINE_SEALANT-AUS_GHS.pdf). This silane coupling agent forms chemical bonds between the silicone polymer and the substrate — critical for lasting adhesion to the materials common in marine construction, including gelcoat, fibreglass, metals, and plastics.

Methyl ethyl ketoxime (CAS 96-29-7) is present at less than 1% w/w (SELLEYS_AUTO_FIX_MARINE_SEALANT-AUS_GHS.pdf). It works as a cure catalyst and is also released as a byproduct during the moisture-cure reaction. Its release during curing produces the characteristic odour associated with oxime-cure silicones and contributes to the safety considerations outlined below.

The rest of the formulation consists of ingredients determined to be non-hazardous or below reporting limits (SELLEYS_AUTO_FIX_MARINE_SEALANT-AUS_GHS.pdf), including the silicone polymer base, gap-filling fillers, pigments, and additional processing aids.

Hazard classification & safety profile

Selleys Auto Fix Marine Sealant is classified as hazardous under Safe Work Australia GHS 7 criteria (SELLEYS_AUTO_FIX_MARINE_SEALANT-AUS_GHS.pdf). Knowing these classifications lets you put the right handling protocols in place.

The product carries two primary hazard classifications. Eye Damage/Irritation — Category 2A means the uncured sealant causes serious eye irritation (SELLEYS_AUTO_FIX_MARINE_SEALANT-AUS_GHS.pdf). This reflects the potential for reversible but significant eye tissue damage requiring medical attention. Hazard statement H319 applies (SELLEYS_AUTO_FIX_MARINE_SEALANT-AUS_GHS.pdf).

Sensitisation — Skin — Category 1 identifies this sealant as a skin sensitiser capable of triggering allergic reactions (SELLEYS_AUTO_FIX_MARINE_SEALANT-AUS_GHS.pdf). Hazard statement H317 warns that the product may cause an allergic skin reaction (SELLEYS_AUTO_FIX_MARINE_SEALANT-AUS_GHS.pdf). This matters for repeated or prolonged skin exposure. Sensitisation can develop over time even in people who initially tolerate contact — and once sensitised, further exposures can trigger progressively severe dermatological reactions.

The Warning signal word applies (SELLEYS_AUTO_FIX_MARINE_SEALANT-AUS_GHS.pdf), indicating moderate hazard severity that requires strict adherence to precautionary measures.

The hazard profile does not include classifications for oral toxicity, respiratory sensitisation, carcinogenicity, reproductive toxicity, or aquatic toxicity based on available safety data. The absence of these classifications means either the classification thresholds were not met or sufficient data were not available — it does not mean the product carries zero risk in these areas.

This product is not classified as Dangerous Goods under the Australian Code for the Transport of Dangerous Goods by Road & Rail or the New Zealand NZS5433 standard (SELLEYS_AUTO_FIX_MARINE_SEALANT-AUS_GHS.pdf), which keeps logistics straightforward for marine professionals transporting the sealant to dock locations or aboard vessels. No Hazchem Code applies (SELLEYS_AUTO_FIX_MARINE_SEALANT-AUS_GHS.pdf).

No Poison Schedule classification applies to this product (SELLEYS_AUTO_FIX_MARINE_SEALANT-AUS_GHS.pdf), placing it outside the scheduling framework for therapeutic goods and poisons in Australia.

Personal protective equipment & exposure prevention

Wear protective gloves, protective clothing, and eye/face protection (SELLEYS_AUTO_FIX_MARINE_SEALANT-AUS_GHS.pdf). For gloves, nitrile rubber provides suitable barrier protection for intermittent contact, though your final selection should account for glove construction variations and your specific working conditions (SELLEYS_AUTO_FIX_MARINE_SEALANT-AUS_GHS.pdf). Given the skin sensitisation hazard, gloves must provide complete barrier protection. Inspect them before every use for tears or degradation, and replace contaminated gloves immediately.

Eye and face protection is essential given the Category 2A eye irritation classification. Chemical goggles are the right choice for marine sealant application (SELLEYS_AUTO_FIX_MARINE_SEALANT-AUS_GHS.pdf). Safety glasses with side shields don't provide adequate protection when working overhead or in confined marine spaces where sealant can drip or be wiped toward the face.

Protective overalls give full-body coverage suited to marine maintenance work (SELLEYS_AUTO_FIX_MARINE_SEALANT-AUS_GHS.pdf). In engine compartments, bilges, or other tight spaces common on vessels, long sleeves and full leg coverage are especially important.

Safety shoes complete the recommended PPE ensemble for first aiders and are worth considering for applicators in industrial marine settings (SELLEYS_AUTO_FIX_MARINE_SEALANT-AUS_GHS.pdf).

Respiratory protection is not explicitly specified in the safety data, though you must avoid breathing dust, fume, gas, mist, vapours, or spray (SELLEYS_AUTO_FIX_MARINE_SEALANT-AUS_GHS.pdf). The release of methyl ethyl ketoxime during curing produces a noticeable odour. In confined marine spaces with poor ventilation — below-deck compartments or enclosed engine rooms — respiratory protection is a sensible precaution even where not mandated by the classification.

Contaminated work clothing must not leave the workplace (SELLEYS_AUTO_FIX_MARINE_SEALANT-AUS_GHS.pdf). Remove and wash contaminated clothing before reuse (SELLEYS_AUTO_FIX_MARINE_SEALANT-AUS_GHS.pdf) to prevent secondary exposure to others handling those garments.

Wash hands, face, and all exposed skin thoroughly after handling (SELLEYS_AUTO_FIX_MARINE_SEALANT-AUS_GHS.pdf), and always wash hands before smoking, eating, drinking, or using the toilet (SELLEYS_AUTO_FIX_MARINE_SEALANT-AUS_GHS.pdf). These habits prevent inadvertent ingestion and reduce cumulative skin exposure that can lead to sensitisation.

Keep the product out of reach of children (SELLEYS_AUTO_FIX_MARINE_SEALANT-AUS_GHS.pdf). Read all instructions carefully and follow them completely (SELLEYS_AUTO_FIX_MARINE_SEALANT-AUS_GHS.pdf).

Application & handling guidelines

Before you start, ensure the work area has adequate ventilation. Marine environments often involve below-deck or enclosed spaces where vapour can build up. The oxime chemistry releases vapours during application and cure — disperse them through natural or forced ventilation.

Surface preparation is the foundation of strong adhesion. The silane coupling agent in the formulation bonds chemically to properly prepared substrates, so surfaces must be clean, dry, and free from oils, release agents, or old sealant residues that would block that bond from forming.

Apply sealant in a continuous bead to prevent air entrapment. The 75g cartridge works with standard caulking guns for controlled, precise dispensing. Tool the bead while still uncured to ensure full substrate contact and achieve the profile you need.

The moisture-cure chemistry means ambient humidity drives the curing reaction. In marine environments, atmospheric moisture is typically abundant — ideal for consistent cure progression. In very dry conditions or with especially thick beads, cure may be slower or incomplete in interior sections.

Stay aware of the skin sensitisation hazard throughout application. Even with gloves on, avoid unnecessary contact. If sealant reaches skin despite your protective measures, follow the first aid procedures detailed below without delay.

The oxime crosslinker technology makes this a neutral-cure silicone system. Unlike acid-cure silicones that release acetic acid and can corrode metals, the neutral cure is compatible with the full range of marine substrates — including the metals found in marine hardware and fittings.

First aid procedures

If exposure occurs despite your precautions, act immediately and follow these manufacturer-specified procedures for each exposure route.

For inhalation exposure, move the affected person away from the source without putting yourself at risk (SELLEYS_AUTO_FIX_MARINE_SEALANT-AUS_GHS.pdf). This matters especially in confined marine spaces where rescuers can be overcome in poorly ventilated compartments. Remove contaminated clothing and loosen remaining clothing. Let the person rest in the most comfortable position, keep them warm, and allow full recovery before resuming activity (SELLEYS_AUTO_FIX_MARINE_SEALANT-AUS_GHS.pdf). Seek medical advice if effects persist (SELLEYS_AUTO_FIX_MARINE_SEALANT-AUS_GHS.pdf).

For skin contact, act promptly given the sensitisation hazard. Effects may be delayed (SELLEYS_AUTO_FIX_MARINE_SEALANT-AUS_GHS.pdf) — symptoms don't always appear immediately. Remove contaminated clothing and flush skin and hair thoroughly with running water (SELLEYS_AUTO_FIX_MARINE_SEALANT-AUS_GHS.pdf). If swelling, redness, blistering, or irritation develops, seek medical assistance (SELLEYS_AUTO_FIX_MARINE_SEALANT-AUS_GHS.pdf). If a skin rash appears, get medical advice without delay (SELLEYS_AUTO_FIX_MARINE_SEALANT-AUS_GHS.pdf). Don't dismiss a skin reaction as minor — it may be the start of sensitisation that requires medical documentation and workplace accommodation.

Eye contact requires immediate, sustained irrigation. Hold eyelids apart and flush continuously with running water (SELLEYS_AUTO_FIX_MARINE_SEALANT-AUS_GHS.pdf). Keep flushing until the Poisons Information Centre or a doctor advises you to stop — or for a minimum of 15 minutes — then transport to a doctor or hospital (SELLEYS_AUTO_FIX_MARINE_SEALANT-AUS_GHS.pdf). Remove contact lenses if present and easy to do, then continue rinsing (SELLEYS_AUTO_FIX_MARINE_SEALANT-AUS_GHS.pdf). If eye irritation continues after irrigation, seek medical advice (SELLEYS_AUTO_FIX_MARINE_SEALANT-AUS_GHS.pdf). The 15-minute minimum flush is non-negotiable — serious eye irritation requires thorough dilution and complete removal of the irritant.

For ingestion, rinse the mouth with water (SELLEYS_AUTO_FIX_MARINE_SEALANT-AUS_GHS.pdf). Do NOT induce vomiting (SELLEYS_AUTO_FIX_MARINE_SEALANT-AUS_GHS.pdf). Give the person a glass of water to drink, and never give anything by mouth to an unconscious person. If vomiting occurs, give further water (SELLEYS_AUTO_FIX_MARINE_SEALANT-AUS_GHS.pdf). Seek medical advice (SELLEYS_AUTO_FIX_MARINE_SEALANT-AUS_GHS.pdf).

For poisoning from any exposure route, contact a doctor or Poisons Information Centre immediately on the 24-hour emergency lines: Australia — 1800 220 770; New Zealand — 0800 220 770 (SELLEYS_AUTO_FIX_MARINE_SEALANT-AUS_GHS.pdf). Standard telephone support is available at 1300 555 205 (SELLEYS_AUTO_FIX_MARINE_SEALANT-AUS_GHS.pdf).

When seeking medical advice, have the product container or label on hand (SELLEYS_AUTO_FIX_MARINE_SEALANT-AUS_GHS.pdf). Medical professionals need specific product identification and composition information to provide the right treatment.

Physicians should treat symptomatically, noting that effects may be delayed (SELLEYS_AUTO_FIX_MARINE_SEALANT-AUS_GHS.pdf). This is especially relevant for skin sensitisation, which can develop hours after exposure or emerge only after repeated contact over time.

Fire safety & emergency response

Selleys Auto Fix Marine Sealant is classified as combustible material (SELLEYS_AUTO_FIX_MARINE_SEALANT-AUS_GHS.pdf).

If the material is involved in fire, use water fog or fine water spray where fog systems are not available (SELLEYS_AUTO_FIX_MARINE_SEALANT-AUS_GHS.pdf). Alcohol-resistant foam, standard foam, and dry agents including carbon dioxide and dry chemical powder are all suitable (SELLEYS_AUTO_FIX_MARINE_SEALANT-AUS_GHS.pdf). The range of acceptable extinguishing agents gives marine professionals flexibility — useful when water supplies are limited or proximity to electrical equipment makes dry agents the better choice.

Water fog is preferred over straight streams. Fog patterns maximise cooling while reducing water damage to marine equipment and cutting the risk of spreading burning liquid sealant. The recommendation for alcohol-resistant foam indicates the sealant or its decomposition products may be polar in nature, requiring specialised foam formulations for effective suppression.

Burning or decomposing sealant may emit toxic fumes (SELLEYS_AUTO_FIX_MARINE_SEALANT-AUS_GHS.pdf). Given the organosilicone chemistry with oxime functional groups, combustion products are likely to include carbon monoxide, carbon dioxide, nitrogen oxides, and potentially silica particulates or volatile silicon-containing compounds — inhalation hazards well beyond those of the uncured material.

Firefighters must wear self-contained breathing apparatus and appropriate protective clothing wherever exposure to vapour or combustion products is possible (SELLEYS_AUTO_FIX_MARINE_SEALANT-AUS_GHS.pdf). This applies even to small fires in marine spaces where restricted ventilation allows combustion products to concentrate quickly.

No Hazchem Code applies to this product (SELLEYS_AUTO_FIX_MARINE_SEALANT-AUS_GHS.pdf), so emergency responders do not need to reference Hazchem protocols when dealing with fires involving this sealant.

Spill management & containment

For small spills, put on your protective equipment before starting cleanup — gloves, eye protection, and protective clothing (SELLEYS_AUTO_FIX_MARINE_SEALANT-AUS_GHS.pdf). Avoid inhaling vapours or dust (SELLEYS_AUTO_FIX_MARINE_SEALANT-AUS_GHS.pdf). While the sealant is a paste or liquid, cleanup can generate dust if dried material is disturbed, and uncured spilled material continues to release vapours throughout the process.

Wipe up spills with absorbent materials such as clean rags or paper towels (SELLEYS_AUTO_FIX_MARINE_SEALANT-AUS_GHS.pdf). The 75g cartridge format means spills are manageable through absorbent wipes rather than requiring containment booms or vacuum systems.

The safety data does not include specific procedures for large-scale spills, reflecting the small package size. If multiple cartridges are damaged together — in a storage locker collision or vessel impact, for example — apply the same protective equipment and absorption principles, scaled to the volume involved.

All waste material collected from spills must be disposed of in accordance with local, regional, national, and international regulations (SELLEYS_AUTO_FIX_MARINE_SEALANT-AUS_GHS.pdf). This matters for marine operations that cross jurisdictional boundaries — comply with the most stringent applicable waste regulations in every location.

In marine environments, keep sealant out of bilges and away from direct waterway entry. Silicone materials are not readily biodegradable and must not be released to the marine environment. Contain and clean up deck spills before any washing operations that could carry residues overboard.

Storage & disposal requirements

Store the product in tightly sealed original containers when not in use. After a cartridge is opened and partially used, the sealant exposed in the nozzle will cure and form a protective plug that shields the remaining material from moisture ingress. Remove this plug before the next use. For longer-term storage of opened cartridges, a dedicated cartridge cap or tape over the nozzle works equally well.

Keep containers out of reach of children as required by the precautionary statements (SELLEYS_AUTO_FIX_MARINE_SEALANT-AUS_GHS.pdf). In marine workshop environments, secure storage lockers and restrict access to chemical stores.

No specific GHS storage precautionary statement is assigned in the classification (SELLEYS_AUTO_FIX_MARINE_SEALANT-AUS_GHS.pdf), confirming storage under normal warehouse or workshop conditions is acceptable. Avoid temperature extremes, direct sunlight, or proximity to heat sources — these conditions can affect shelf life even without creating acute hazards. Specific storage temperature range: Not disclosed by manufacturer.

For disposal, the product container and its contents must be disposed of in accordance with local, regional, national, and international regulations (SELLEYS_AUTO_FIX_MARINE_SEALANT-AUS_GHS.pdf). The multi-jurisdictional reference is particularly relevant for marine operations generating waste in international waters or across multiple port countries.

Empty cartridges retain residual sealant on interior surfaces. These residues carry the same hazard characteristics as the bulk product. Rinse cartridges before recycling if local programmes accept them, or dispose of them as chemical containers following local hazardous waste protocols.

Cured sealant removed during maintenance carries different characteristics than uncured material. Once fully cured, the reactive oxime crosslinkers have been consumed and the material is a crosslinked silicone elastomer. Disposal regulations may still apply based on the material's origin and potential contamination from marine environments — oils, metals, biocides, and similar substances.

Product identification & specifications

Selleys Auto Fix Marine Sealant is manufactured and supplied by a company with Australian Business Number (ABN) 67 000 049 427, operating from 1956 Dandenong Road (SELLEYS_AUTO_FIX_MARINE_SEALANT-AUS_GHS.pdf). Technical support and general enquiries are available at 1300 555 205 (SELLEYS_AUTO_FIX_MARINE_SEALANT-AUS_GHS.pdf).

The 75g package delivers enough material for multiple sealing jobs typical in marine maintenance — porthole gaskets, hatch seals, through-hull fittings, and deck hardware bedding. The cartridge format gives precise application control and keeps waste to a minimum compared to bulk packaging.

The recommended use specification defines this as a general purpose silicone sealant for marine applications (SELLEYS_AUTO_FIX_MARINE_SEALANT-AUS_GHS.pdf). General purpose means versatility across the full range of marine sealing needs. The marine focus means the formulation is optimised for water resistance, UV stability, and salt exposure tolerance that set it apart from standard construction silicones.

Product codes 9300697107084 and 100118 provide manufacturer identification for ordering and inventory systems (SELLEYS_AUTO_FIX_MARINE_SEALANT-AUS_GHS.pdf). Barcodes 9300697107084 and 9300697124845 support retail scanning and warehouse tracking (SELLEYS_AUTO_FIX_MARINE_SEALANT-AUS_GHS.pdf).

The 1–10% w/w concentration of the primary methylsilylidyne crosslinker delivers the curing capacity, while the less than 1% concentrations of adhesion promoter, secondary crosslinker, and processing aids fine-tune application characteristics and final properties (SELLEYS_AUTO_FIX_MARINE_SEALANT-AUS_GHS.pdf).

The GHS classification under Safe Work Australia GHS 7 criteria establishes the regulatory framework for workplace handling (SELLEYS_AUTO_FIX_MARINE_SEALANT-AUS_GHS.pdf). The Warning signal word, Eye Irritation Category 2A, and Skin Sensitisation Category 1 classifications drive the PPE requirements and handling protocols detailed throughout this guide (SELLEYS_AUTO_FIX_MARINE_SEALANT-AUS_GHS.pdf).

Related Products & Brand Context

Selleys Auto Fix Marine Sealant (75g) sits within the Home & Garden > Sealants & Adhesives category, specifically under the Auto Sealants sub-range produced by Selleys. Selleys is an Australian household and trade brand with a long-standing presence in the sealants, adhesives, and gap-filling segment. Within their sealant lineup, this product is positioned as a specialist marine-grade option — distinct from general-purpose or construction silicones by virtue of its salt spray resistance, UV stability, and vibration tolerance, all properties demanded by the boat and marine maintenance context.

The product itself is a neutral-curing silicone, which means it releases less acetic acid during curing compared to acetoxy-cure silicones. This makes it better suited to sensitive marine surfaces such as metals and painted substrates that can be damaged by acidic off-gassing. The translucent finish allows it to blend cleanly against a range of hull and fitting colours without leaving a visible bead line. Its temperature resistance — rated from -60°C to +180°C continuously and up to +240°C intermittently — places it at the more performance-oriented end of the sealant spectrum.

Because the knowledge graph context returned no sibling product records for this guide, specific related Selleys product names cannot be confirmed here. Readers researching the broader Selleys Auto Fix range should visit the brand's Australian product pages directly to identify companion products such as other auto or marine sealants in the lineup.

For someone using this sealant, the most likely adjacent products are surface preparation items — cleaning solvents or degreasers to ensure the bonding surfaces are free of salt, grease, and old sealant residue before application — as well as a sealant gun or applicator tool sized for a 75g cartridge. Masking tape is also commonly used alongside tube-applied sealants to achieve a clean bead line on visible joints. These use-case adjacent products typically fall in the surface preparation and tool accessories categories within the same Home & Garden domain.
