Where silicone or acrylic alternatives fall short, Flexiseal's polyurethane chemistry fills the gap — professionals and DIYers have been reaching for it for that reason. As a core product in the Selleys construction sealants range, it's engineered for applications that demand what polyurethane chemistry specifically delivers.\n\nManufactured by Selleys, a division of DuluxGroup (Australia) Pty Ltd, Flexiseal is distributed across Australian and New Zealand markets with full compliance to local safety standards (SDS). This guide covers composition, handling protocols, safety profile, and operational requirements — all drawn from manufacturer documentation. Selleys has been in the business for over 80 years, and that history sits behind every cartridge.\n\n## Available formats and variants\n\nFlexiseal comes in six SKU configurations across three colours — Black, Grey, and White — each available in consumer and professional packaging (SDS).\n\n**Consumer range (300mL cartridges):**\n- Selleys Flexiseal Black 300mL (Product Code: 101205, Barcode: 9300697127624)\n- Selleys Flexiseal Grey 300mL (Product Code: 101206, Barcode: 9300697127631)\n- Selleys Flexiseal White 300mL (Product Code: 101204, Barcode: 9300697127617)\n\n**Professional range (600mL cartridges):**\n- Proseries Flexiseal Black 600mL (Product Code: 930069712332902, Barcode: 9300697123329)\n- Proseries Flexiseal Grey 600mL (Product Code: 930069712331202, Barcode: 9300697123312)\n- Proseries Flexiseal White 600mL (Product Code: 930069712330502, Barcode: 9300697123305)\n\nThe 600mL Proseries cartridge holds double the volume of the consumer format. On larger jobs, that means fewer stops to reload without any change to the chemical formulation — same product, same results, regardless of colour or size (SDS).\n\n## Chemistry and composition\n\nFlexiseal's performance comes from its polyurethane-based formulation. Four chemical constituents are declared above reporting thresholds; the rest of the formulation is proprietary and classified as non-hazardous (SDS).\n\n**Active chemical components:**\n\nXylene is the primary solvent, present at 1–10% by weight (SDS). It controls viscosity, application properties, and curing behaviour. This aromatic hydrocarbon accounts for the product's odour and evaporates during curing.\n\nThe reactive component is 4,4'-diphenylmethane diisocyanate (MDI), present below 1% by weight (SDS). MDI reacts with atmospheric moisture to build the cured polymer network — this is the mechanism that makes polyurethane sealants perform differently from silicone or acrylic products.\n\nEthyl acetate is present below 1% by weight (SDS), working as a co-solvent that adjusts flow characteristics and evaporation rate. Under Australian occupational exposure standards, it carries a TWA of 200 ppm (720 mg/m³) and a STEL of 400 ppm (1440 mg/m³) (SDS).\n\nPhenol, nonyl-, phosphite (3:1) is present below 1% by weight (SDS), acting as a stabiliser against oxidative degradation during storage and application.\n\nThe remaining formulation components — the majority of the product by weight — are non-hazardous or present below mandatory reporting thresholds (SDS). This proprietary blend includes polymers, fillers, pigments, and processing aids that determine colour, consistency, and final performance.\n\n## Hazard classification and regulatory status\n\nFlexiseal is not classified as hazardous under the criteria established by Safe Work Australia GHS 7, based on full toxicological and physicochemical data (SDS). That classification directly shapes the handling, storage, and documentation requirements that apply.\n\nIt carries no Poison Schedule designation under the Standard for the Uniform Scheduling of Medicines and Poisons (SDS). For transport, it 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 (SDS). No Hazchem code applies, and standard freight protocols are sufficient (SDS).\n\nThis means Flexiseal contains chemical constituents that call for sensible handling, but it does not trigger the documentation, labelling, or specialised transport requirements that apply to hazardous materials under Australian and New Zealand law.\n\n## Personal protective equipment requirements\n\nA non-hazardous classification doesn't mean skipping PPE. The recommended gear addresses the specific exposure pathways associated with polyurethane sealant application (SDS).\n\n**Respiratory protection:**\nWhen inhalation risk exists, wear an organic vapour/particulate respirator meeting AS/NZS 1715 and AS/NZS 1716 (SDS). This matters most in confined spaces, during bulk application, or anywhere ventilation is limited. The organic vapour specification targets the xylene and ethyl acetate components directly.\n\n**Hand protection:**\nNitrile rubber gloves provide adequate protection for intermittent contact (SDS). Glove construction and local working conditions vary, so assess based on your specific situation (SDS). Breakthrough time differs with manufacturer, thickness, and contamination levels — inspect and replace gloves regularly.\n\n**Eye protection:**\nSafety glasses or goggles are required to prevent eye contact during application (SDS). The solvent content poses a real irritation risk, so wear eyewear with side protection against splashes.\n\n**Body protection:**\nOveralls and safety shoes are the baseline (SDS). This stops skin contact during application and protects against slips — Flexiseal becomes slippery when spilled (SDS).\n\n**Hygiene practices:**\nWash hands before smoking, eating, drinking, or using toilet facilities (SDS). Wash contaminated clothing and protective equipment before storing or reusing them (SDS).\n\n## Handling protocols\n\nThe manufacturer specifies three primary precautions for routine handling (SDS).\n\nAvoid eye contact and repeated or prolonged skin contact throughout every phase of use (SDS). Brief contact is addressed by washing protocols, but sustained exposure increases absorption potential and irritation risk. Avoid inhaling dust generated during dried sealant removal or surface preparation (SDS) — standard application generates minimal particulate, but removal work is a different matter.\n\nAdequate ventilation is the primary engineering control for managing solvent vapour exposure. In enclosed spaces or during extended application sessions, use mechanical ventilation or respiratory protection to keep atmospheric concentrations below the ethyl acetate TWA of 200 ppm (SDS).\n\n## Storage requirements\n\nStore in a cool, dry, well-ventilated location away from direct sunlight (SDS). Elevated temperatures accelerate moisture-cure reactions inside the cartridge, which can cause hardening or pressure buildup. Sunlight degrades the plastic cartridge and can affect the formulation.\n\nKeep Flexiseal away from foodstuffs (SDS). Store well away from strong oxidising agents, strong acids, and strong bases, which can react with the isocyanate chemistry or solvent components (SDS).\n\nMaintain separation from heat sources and ignition sources. Flexiseal is a combustible material, even though it is not classified as Dangerous Goods (SDS) — that distinction matters for fire safety planning.\n\nStore cartridges upright at all times to prevent seal failure (SDS). Keep containers securely closed when not in use, and check regularly for spills (SDS).\n\n## Fire safety considerations\n\nFlexiseal is a combustible material, and knowing the correct fire response matters for any facility storing or using it in quantity (SDS).\n\n**Suitable extinguishing methods:**\nUse water fog as the primary extinguishing agent, or fine water spray if fog equipment is unavailable (SDS). Alcohol-resistant foam, standard foam, dry chemical powder, and carbon dioxide are all effective alternatives (SDS).\n\n**Combustion hazards:**\nBurning or thermally decomposing Flexiseal can emit toxic fumes (SDS). Firefighters must wear self-contained breathing apparatus and suitable protective clothing if any risk of exposure to vapour or combustion products exists (SDS). Likely toxic combustion products include carbon monoxide, nitrogen oxides from the MDI component, and aromatic compounds from incomplete combustion of xylene.\n\nThe combination of combustible classification and solvent content means ignition sources pose a real fire risk during application. Keep open flames, sparks, and hot work well clear of active application areas and wet sealant.\n\n## Spill response and cleanup procedures\n\nSpill response depends on volume, with distinct procedures for small and large releases (SDS).\n\n**Small spill management:**\nPut on protective equipment, then wipe up the material with absorbent materials such as clean rags or paper towels (SDS). Seal contaminated absorbents in properly labelled containers and dispose of them according to local waste regulations (SDS).\n\n**Large spill management:**\nClear all unprotected personnel from the area immediately (SDS). Spilled sealant is slippery, so move quickly to prevent accidents (SDS). Response personnel must wear full protective equipment and work upwind or under enhanced ventilation (SDS).\n\nCover large spills with damp absorbent material — sand or soil works well (SDS). Dampening prevents dust generation during handling. Sweep or vacuum while avoiding dust generation, then seal the collected material in labelled containers for disposal (SDS).\n\n**Environmental contamination:**\nIf a spill reaches crops, sewers, or waterways, contact local emergency services immediately (SDS). Xylene in particular poses serious environmental concerns in water systems or soil.\n\n## First aid procedures\n\nFirst aid protocols cover all four primary exposure routes (SDS).\n\n**Inhalation exposure:**\nMove the affected person away from the exposure area without becoming a casualty yourself (SDS). Remove contaminated clothing and loosen remaining garments to ease breathing (SDS). Keep the patient comfortable, warm, and resting until fully recovered (SDS). If effects persist, seek medical advice (SDS).\n\n**Skin contact:**\nRemove contaminated clothing immediately and flush the affected area with running water (SDS). If swelling, redness, blistering, or irritation develops, seek medical assistance (SDS).\n\n**Eye contact:**\nWash eyes with water immediately (SDS). Seek medical advice in every case of eye contamination, even when irritation is not obvious (SDS).\n\n**Ingestion:**\nRinse the mouth with water but do NOT induce vomiting (SDS). Give a glass of water to drink — nothing by mouth to an unconscious patient (SDS). If vomiting occurs on its own, give more water (SDS). Seek medical advice for every ingestion incident regardless of quantity (SDS).\n\n**Medical treatment:**\nHealthcare providers should treat symptomatically — no specific antidote exists for polyurethane sealant exposure (SDS). First aiders should wear safety shoes, overalls, gloves, safety glasses, and a respirator while providing care (SDS).\n\n**Emergency contact information:**\nFor poisoning incidents, contact a doctor or Poisons Information Centre immediately — phone 131 126 in Australia or 0800 764 766 in New Zealand (SDS). For product-specific emergency guidance, Selleys operates a 24-hour emergency line: 1800 220 770 in Australia or 0800 220 770 in New Zealand (SDS).\n\n## Technical support and documentation\n\nSelleys customer service is reachable at 1300 555 205 (SDS) for application questions, compatibility enquiries, and product specification details beyond what the safety documentation covers. When contacting Selleys for technical support or emergency response, reference your specific product code and colour variant. Because the formulation is consistent across all six SKU configurations, composition-related guidance applies equally across the range.\n\n## References\n\n- Source PDF:

Within the Selleys range, this product sits under the **Pro Series** line — positioned as a higher-performance tier aimed at demanding applications rather than basic gap-filling tasks. The product's formal category placement is **Home & Garden > Sealants & Caulking**, which groups it alongside other gap and joint sealing solutions rather than, for example, structural adhesives or surface coatings.\n\nWithin the sealants category, Flexiseal Multipurpose Sealant is distinguished by its polyurethane formulation and its rated joint movement capability of ±125%, which is notably high for a general-purpose sealant. This makes it more suitable for joints that experience ongoing expansion and contraction — such as those around windows, doors, control joints, and cladding — compared to standard acrylic or silicone sealants that typically handle less movement. Its non-slumping, low-modulus formula also means it can be applied to vertical surfaces and overhead joints without running out of position before it cures.\n\nFrom a use-case perspective, buyers selecting this sealant are likely to also need a few complementary products. A standard caulking gun is required for application from a cartridge format. Surface primers may be relevant where adhesion to non-porous or difficult substrates is needed, and masking tape is commonly used alongside sealants to achieve clean joint edges. Once cured, the product is paintable, so it sits comfortably in workflows that include finishing coats — meaning interior or exterior paints from any brand would follow naturally in the same project.\n\nThe knowledge graph does not identify specific named sibling sealant products within the Selleys range beyond the Pro Series Flexiseal itself, so direct product-to-product comparisons within the Selleys catalogue cannot be drawn from the available data. Readers comparing this product to other Selleys sealants should consult the full Selleys product listing at selleys.com.au for a complete picture of the range.\n<!-- nor-3601:relationships-end -->\n",
