This polyurethane chemistry product sits between rigid sealants and flexible adhesives, using a moisture-curing polymer system designed for general sealing and bonding tasks that need professional results. It's classified as non-hazardous under Safe Work Australia GHS 7, which makes it a practical choice for residential, commercial, and light industrial settings where you need a versatile, dependable sealant (SELLEYS_FLEXISEAL_SEALANT-AUS_GHS.pdf). Polyurethane sealants cure through a reaction with atmospheric moisture, forming a durable elastomeric seal. Flexiseal's formulation balances smooth workability during application with solid mechanical properties after cure. Whether you're a tradesperson or a weekend DIYer, understanding the product's composition, safety profile, and handling requirements gives you the confidence to get clean results on projects from weatherproofing to light-duty bonding. ## Chemistry and composition Flexiseal's performance comes from its polyurethane chemistry foundation, with several chemical constituents working together to deliver its sealing and adhesive properties. ### Primary components The formulation contains xylene at 1–10% by weight (SELLEYS_FLEXISEAL_SEALANT-AUS_GHS.pdf). Xylene acts as a solvent, controlling viscosity during application and helping the polymer flow and wet surfaces effectively. It evaporates as the sealant cures, driving the transition from a workable paste to a solid, resilient elastomer. The product also contains 4,4'-diphenylmethane diisocyanate (MDI) at less than 1% by weight (SELLEYS_FLEXISEAL_SEALANT-AUS_GHS.pdf). MDI is the reactive component in polyurethane chemistry, crosslinking with moisture and other reactive groups to form the urethane bonds that give the cured sealant its structural integrity. The low concentration keeps isocyanate content to a minimum while maintaining performance. Ethyl acetate appears at less than 1% by weight (SELLEYS_FLEXISEAL_SEALANT-AUS_GHS.pdf). It works as a co-solvent alongside xylene to achieve the right consistency and application properties. Its fast evaporation rate contributes to initial skinning and tack-free time. ### Stabilisation system Phenol, nonyl-, phosphite (3:1) is present at less than 1% by weight (SELLEYS_FLEXISEAL_SEALANT-AUS_GHS.pdf). This phosphite compound is an antioxidant and processing stabiliser that protects the polymer from degradation during storage and prevents premature crosslinking before application. The 3:1 designation refers to the stoichiometric ratio of phenol groups to phosphite centres in the additive molecule. The remaining composition consists of ingredients that are non-hazardous or present below reporting limits (SELLEYS_FLEXISEAL_SEALANT-AUS_GHS.pdf). This typically includes polyurethane prepolymers, plasticisers, fillers, pigments, and process aids that contribute to the product's final colour, consistency, and cured properties. ## Product range and availability Flexiseal comes in three colours and two package sizes. ### Colour options The product line includes Black, Grey, and White variants (SELLEYS_FLEXISEAL_SEALANT-AUS_GHS.pdf). These options make it straightforward to match common building materials and architectural finishes. Black works well where the sealant line should recede visually or complement dark substrates. Grey is a neutral option that suits concrete, masonry, and metal. White is the natural choice for projects requiring a clean finish or a match to white painted surfaces, tiles, or sanitaryware. ### Package configurations The 300mL cartridge is designed for standard caulking guns and suits typical residential projects, small repairs, and applications where moderate quantities are needed (SELLEYS_FLEXISEAL_SEALANT-AUS_GHS.pdf). Product codes: Flexiseal Black 300mL is 101205, Grey 300mL is 101206, and White 300mL is 101204 (SELLEYS_FLEXISEAL_SEALANT-AUS_GHS.pdf). The Proseries line comes in 600mL packaging for professional and high-volume users (SELLEYS_FLEXISEAL_SEALANT-AUS_GHS.pdf). The larger cartridges reduce packaging waste and cartridge changes during extensive sealing runs. Product codes: Proseries Flexiseal Black 600mL is 930069712332902, Grey 600mL is 930069712331202, and White 600mL is 930069712330502 (SELLEYS_FLEXISEAL_SEALANT-AUS_GHS.pdf). ## Safety classification and regulatory status Flexiseal's regulatory classification sets out how it must be handled, transported, and labelled. ### Hazard classification Flexiseal is not classified as hazardous under the criteria of Safe Work Australia GHS 7 (SELLEYS_FLEXISEAL_SEALANT-AUS_GHS.pdf). This confirms that the product does not meet the concentration thresholds or exposure criteria that trigger hazard labelling under the Globally Harmonised System of Classification and Labelling of Chemicals. Individual chemical components carry their own hazard profiles, but the formulated product's overall composition and concentration levels don't warrant hazardous classification. The product carries no Poison Schedule designation in Australia (SELLEYS_FLEXISEAL_SEALANT-AUS_GHS.pdf), so it's not subject to the scheduling controls that govern the supply and use of poisons and therapeutic substances. ### Transport classification Flexiseal is not classified as Dangerous Goods under the Australian Code for the Transport of Dangerous Goods by Road & Rail or the New Zealand NZS5433: Transport of Dangerous Goods on Land (SELLEYS_FLEXISEAL_SEALANT-AUS_GHS.pdf). No placarding, segregation, or special documentation is required for dangerous goods shipments. No Hazchem Code applies (SELLEYS_FLEXISEAL_SEALANT-AUS_GHS.pdf). ## Combustibility and fire characteristics Flexiseal is not a dangerous good, but it does have combustibility characteristics that matter for fire safety. ### Fire behaviour Flexiseal is classified as a combustible material (SELLEYS_FLEXISEAL_SEALANT-AUS_GHS.pdf). It can ignite and burn under fire conditions, though it doesn't meet the criteria for classification as a flammable liquid or solid. The combustibility comes from its organic polymer base and solvent content, which can support combustion once sufficient heat is applied. ### Firefighting approach Suitable extinguishing media include water fog (or fine water spray if water fog is unavailable), alcohol-resistant foam, standard foam, dry chemical powder, or carbon dioxide (SELLEYS_FLEXISEAL_SEALANT-AUS_GHS.pdf). This range gives emergency responders flexibility depending on available equipment and the nature of the fire. When burning or decomposing, Flexiseal can emit toxic fumes (SELLEYS_FLEXISEAL_SEALANT-AUS_GHS.pdf). Incomplete combustion of organic compounds produces carbon monoxide, nitrogen oxides, and other hazardous gases. Firefighters must wear self-contained breathing apparatus and suitable protective clothing if there is risk of exposure to vapour or products of combustion or decomposition (SELLEYS_FLEXISEAL_SEALANT-AUS_GHS.pdf). ## Personal protective equipment requirements Safe handling of Flexiseal requires the right PPE matched to each exposure pathway. ### Eye and face protection Safety glasses are recommended during Flexiseal application to protect against eye contact (SELLEYS_FLEXISEAL_SEALANT-AUS_GHS.pdf). This guards against splashes during dispensing, spreading, or cleanup. The product's solvent content makes eye contact particularly undesirable, as it causes discomfort and irritation requiring immediate flushing. ### Hand protection Nitrile rubber gloves are suitable for intermittent contact with Flexiseal (SELLEYS_FLEXISEAL_SEALANT-AUS_GHS.pdf). Nitrile rubber resists xylene and other organic solvents in the formulation. Glove performance depends on construction quality and local conditions, so users should assess their specific glove materials and work practices before starting (SELLEYS_FLEXISEAL_SEALANT-AUS_GHS.pdf). ### Respiratory protection Where an inhalation risk exists, workers should wear an organic vapour/particulate respirator meeting AS/NZS 1715 and AS/NZS 1716 (SELLEYS_FLEXISEAL_SEALANT-AUS_GHS.pdf). Respiratory protection is especially important in confined spaces, poorly ventilated areas, or when applying large quantities. Organic vapour cartridges capture xylene and ethyl acetate vapours, while particulate filtration handles any misting during application. ### Body protection and work practices Overalls and safety shoes complete the recommended PPE (SELLEYS_FLEXISEAL_SEALANT-AUS_GHS.pdf). These prevent skin contact and protect feet from dropped cartridges or spills. Ensure adequate ventilation when using Flexiseal to keep vapour levels in the breathing zone under control (SELLEYS_FLEXISEAL_SEALANT-AUS_GHS.pdf). Wash hands before smoking, eating, drinking, or using the toilet (SELLEYS_FLEXISEAL_SEALANT-AUS_GHS.pdf). This prevents ingestion of product residues that transfer from contaminated hands. Contaminated clothing and protective equipment must be washed before storing or re-using (SELLEYS_FLEXISEAL_SEALANT-AUS_GHS.pdf). ## Handling precautions Good handling technique keeps exposure low and product integrity high. ### Safe work practices Avoid eye contact and repeated or prolonged skin contact during handling (SELLEYS_FLEXISEAL_SEALANT-AUS_GHS.pdf). The solvent content can cause skin irritation with extended contact, and eye splash requires immediate attention. Avoid inhaling dust (SELLEYS_FLEXISEAL_SEALANT-AUS_GHS.pdf) — this applies mainly to cleanup of dried product or disposal of cured waste rather than normal application. ## Storage requirements Correct storage protects Flexiseal's performance and extends shelf life. ### Environmental controls Store in a cool, dry, well-ventilated place out of direct sunlight (SELLEYS_FLEXISEAL_SEALANT-AUS_GHS.pdf). Heat accelerates chemical reactions in polyurethane formulations, which can cause premature curing or viscosity changes. Moisture exposure through damaged packaging can trigger curing reactions before the product is dispensed. Direct sunlight adds both heat and UV radiation, which degrades polymer components and affects colour stability. ### Segregation and container management Keep Flexiseal away from foodstuffs to prevent contamination (SELLEYS_FLEXISEAL_SEALANT-AUS_GHS.pdf). Store away from incompatible materials described in Section 10 of the safety data sheet (SELLEYS_FLEXISEAL_SEALANT-AUS_GHS.pdf). Given its combustible nature, keep the product away from heat and ignition sources (SELLEYS_FLEXISEAL_SEALANT-AUS_GHS.pdf). Store containers upright to prevent leakage through dispensing nozzles or compromised seals (SELLEYS_FLEXISEAL_SEALANT-AUS_GHS.pdf). Keep containers closed when not in use, and check storage areas regularly for spills (SELLEYS_FLEXISEAL_SEALANT-AUS_GHS.pdf). ## First aid measures Fast, correct first aid minimises harm from accidental exposure. ### Inhalation exposure If someone is overcome by vapour exposure, remove them from the contaminated atmosphere — taking care not to become a casualty yourself (SELLEYS_FLEXISEAL_SEALANT-AUS_GHS.pdf). Remove contaminated clothing and loosen any remaining garments (SELLEYS_FLEXISEAL_SEALANT-AUS_GHS.pdf). Let the affected person rest in a comfortable position, keep them warm, and wait until they have fully recovered (SELLEYS_FLEXISEAL_SEALANT-AUS_GHS.pdf). If effects persist, seek medical advice immediately (SELLEYS_FLEXISEAL_SEALANT-AUS_GHS.pdf). ### Skin contact If skin or hair contact occurs, remove contaminated clothing immediately and flush the affected area with running water (SELLEYS_FLEXISEAL_SEALANT-AUS_GHS.pdf). Thorough flushing removes both the sealant and any dissolved chemical constituents. If swelling, redness, blistering, or irritation develops, seek medical assistance (SELLEYS_FLEXISEAL_SEALANT-AUS_GHS.pdf). ### Eye contact Wash eyes immediately and thoroughly with water (SELLEYS_FLEXISEAL_SEALANT-AUS_GHS.pdf). Seek medical advice in all cases of eye contamination (SELLEYS_FLEXISEAL_SEALANT-AUS_GHS.pdf) — even when initial symptoms seem minor, solvent components can cause delayed effects. ### Ingestion If Flexiseal is swallowed, rinse the mouth with water but do not induce vomiting (SELLEYS_FLEXISEAL_SEALANT-AUS_GHS.pdf). Give the affected person a glass of water to drink, but never give anything by mouth to an unconscious patient (SELLEYS_FLEXISEAL_SEALANT-AUS_GHS.pdf). If vomiting occurs naturally, give additional water and seek medical advice (SELLEYS_FLEXISEAL_SEALANT-AUS_GHS.pdf). ### Emergency contact Contact a doctor or Poisons Information Centre immediately if poisoning occurs (SELLEYS_FLEXISEAL_SEALANT-AUS_GHS.pdf). In Australia, call 131 126; in New Zealand, call 0800 764 766 (SELLEYS_FLEXISEAL_SEALANT-AUS_GHS.pdf). For emergency assistance, Australian users can call 1800 220 770 and New Zealand users can call 0800 220 770 (SELLEYS_FLEXISEAL_SEALANT-AUS_GHS.pdf). ## Spill management procedures A fast, well-executed spill response protects people and prevents environmental harm. ### Small spill protocol For minor spills, wear appropriate protective equipment and avoid inhaling vapours or dust (SELLEYS_FLEXISEAL_SEALANT-AUS_GHS.pdf). Wipe up the spilled material using absorbent materials such as clean rags or paper towels (SELLEYS_FLEXISEAL_SEALANT-AUS_GHS.pdf). Seal the contaminated absorbent material in properly labelled containers for disposal according to local regulations (SELLEYS_FLEXISEAL_SEALANT-AUS_GHS.pdf). ### Large spill response Clear the area of all unprotected personnel immediately (SELLEYS_FLEXISEAL_SEALANT-AUS_GHS.pdf). The spilled product creates slippery conditions, so fast cleanup is essential (SELLEYS_FLEXISEAL_SEALANT-AUS_GHS.pdf). Response personnel must wear full protective equipment (SELLEYS_FLEXISEAL_SEALANT-AUS_GHS.pdf). Work upwind or increase ventilation to keep vapour exposure down (SELLEYS_FLEXISEAL_SEALANT-AUS_GHS.pdf). Cover the spilled material with damp absorbent material such as sand or soil — dampening prevents dust generation during collection (SELLEYS_FLEXISEAL_SEALANT-AUS_GHS.pdf). Sweep or vacuum up the covered spill while avoiding dust generation (SELLEYS_FLEXISEAL_SEALANT-AUS_GHS.pdf). Seal all contaminated material in properly labelled containers for disposal (SELLEYS_FLEXISEAL_SEALANT-AUS_GHS.pdf). If the spill has reached crops, sewers, or waterways, advise local emergency services immediately (SELLEYS_FLEXISEAL_SEALANT-AUS_GHS.pdf). ## Occupational exposure limits Workplace exposure limits help maintain safe atmospheric conditions during application. ### Ethyl acetate exposure standards The Time-Weighted Average (TWA) limit for ethyl acetate is 200 ppm or 720 mg/m³, measured over an eight-hour work shift (SELLEYS_FLEXISEAL_SEALANT-AUS_GHS.pdf). The Short-Term Exposure Limit (STEL) is 400 ppm or 1440 mg/m³, applying to 15-minute exposure periods (SELLEYS_FLEXISEAL_SEALANT-AUS_GHS.pdf). Workers can experience these higher concentrations briefly without exceeding safe thresholds, provided the TWA stays within its limit. In well-ventilated open areas, natural air movement typically keeps concentrations well below these limits. Confined spaces or large-scale applications require mechanical ventilation or respiratory protection to stay compliant. ## References - Source PDF:

Within Selleys' range, Flexiseal FC sits under the multi-purpose sealants line, positioned to serve buyers who need a single product that handles both bonding and gap-filling duties rather than purchasing a dedicated adhesive and a separate sealant. The product's canonical category is **Home & Garden > Sealants & Adhesives**, placing it alongside other construction-grade sealing products rather than in craft or specialty adhesive segments. What sets Flexiseal FC apart within the sealant category is its polyurethane formulation combined with ±25% joint movement capability. This makes it better suited to dynamic building joints — around windows, doors, walls, and ceilings — than rigid, low-flexibility sealants. Its ability to bond acrylic shower linings directly to unpainted gypsum plasterboard, cement sheeting, and fibre cement without a primer also gives it a practical advantage on wet-area fit-outs where surface preparation time matters. The product is available in two delivery formats — a **310 mL cartridge** for standard caulking guns and a **600 mL sausage** for sausage guns — meaning buyers working on larger projects can use the same product without switching formulations. From a use-case adjacency perspective, someone applying Flexiseal FC is likely to also need a compatible caulking gun or sausage gun to dispense the product, along with surface cleaning and degreasing supplies to ensure proper adhesion. For wet-area installations such as acrylic shower linings, supplementary waterproof grout or tile adhesive products may also be relevant, as Flexiseal FC is explicitly not recommended for permanent immersion or below-waterline applications. Buyers intending to paint over the finished joint will want to confirm full cure before applying any topcoat, as the product is paintable only after complete curing.
