Formulated to remain wet and sticky inside concealed lap joints, it seals sandwich panels, Alucobond, and metal substrates without drying out, skinning, or cracking over time.\u003c\/p\u003e\n\n \u003ch3\u003eHow it works\u003c\/h3\u003e\n \u003cp\u003eFulasealPro 840NS Sealant operates as a non-drying, permanently plastic sealant. Unlike standard elastomeric curing sealants, this butyl compound remains in a constant paste-like state, ensuring it does not skin or lose its tackiness inside closed assemblies. When clamped between sheet metal, Polystyrene, or Alucobond panels, the non-skinning formulation flows into small gaps to block air and moisture infiltration while resisting the growth of mould and mildew in damp or temperature-controlled environments. Because the chemistry is non-corrosive, it is safe for direct contact with sensitive metals like Zincalume, aluminium, and galvanised iron without the risk of chemical degradation or surface etching. It will not separate or bleed when applied to non-porous surfaces.\u003c\/p\u003e\n\n \u003ch3\u003eNumbers that matter\u003c\/h3\u003e\n \u003cul\u003e\n \u003cli\u003e\n\u003cstrong\u003e-40°C to +50°C service temperature:\u003c\/strong\u003e Maintains its physical properties and sealing performance in extreme cold, preventing the joint barrier from freezing or failing in commercial refrigeration units and deep-freeze cool rooms.\u003c\/li\u003e\n \u003cli\u003e\n\u003cstrong\u003e15 lineal metres coverage:\u003c\/strong\u003e Yields approximately 15 metres of a 5mm bead per cartridge, allowing accurate material estimation for long panel runs and lap joints.\u003c\/li\u003e\n \u003cli\u003e\n\u003cstrong\u003e+5°C to +35°C application temperature:\u003c\/strong\u003e Defines the safe environmental window for gunning the sealant onto cold or warm substrates during panel assembly.\u003c\/li\u003e\n \u003cli\u003e\n\u003cstrong\u003eIndefinite shelf life:\u003c\/strong\u003e Stored between +5°C and +25°C in unopened packaging, the product remains usable without a strict expiration date, reducing stock waste.\u003c\/li\u003e\n \u003c\/ul\u003e\n\n \u003ch3\u003eWhere to use it\u003c\/h3\u003e\n \u003cp\u003eFulasealPro 840NS Sealant is formulated for small joints and concealed applications on the following substrates:\u003c\/p\u003e\n \u003cul\u003e\n \u003cli\u003eSteel, Stainless Steel, Galvanised iron, Zincalume, and Aluminium\u003c\/li\u003e\n \u003cli\u003eSandwich Panels and Alucobond\u003c\/li\u003e\n \u003cli\u003ePolystyrene and Fiberglass\u003c\/li\u003e\n \u003cli\u003eMost plastics (requires pre-testing)\u003c\/li\u003e\n \u003c\/ul\u003e\n\n \u003ch3\u003eLimitations\u003c\/h3\u003e\n \u003cul\u003e\n \u003cli\u003e\n\u003cstrong\u003eNon-elastomeric:\u003c\/strong\u003e Not suitable for joints where movement is expected, or in applications subject to dynamic stress.\u003c\/li\u003e\n \u003cli\u003e\n\u003cstrong\u003eNo exposed weathering:\u003c\/strong\u003e Not suitable where the sealant is exposed to direct weathering or dirt pick-up; use HB Fuller 770 Sanitary Silicone to seal these exposed areas.\u003c\/li\u003e\n \u003cli\u003e\n\u003cstrong\u003eVibration limits:\u003c\/strong\u003e Not suitable for applications involving constant vibration, such as caravans or truck bodies.\u003c\/li\u003e\n \u003cli\u003e\n\u003cstrong\u003eNon-paintable:\u003c\/strong\u003e This product cannot be painted over.\u003c\/li\u003e\n \u003c\/ul\u003e\n\n \u003ch3\u003eApplication clean-up and preparation\u003c\/h3\u003e\n \u003cp\u003eAll surfaces must be clean, dry, sound, and free of dust, oil, old sealant, or other contaminants before application. Clean lightly contaminated surfaces using the two-rag wipe method with Isopropyl Alcohol (IPA) on a clean, lint-free cloth, ensuring the solvent does not dry directly on the substrate. For heavily contaminated surfaces, clean first with a generic wax and grease remover using the two-rag wipe method, followed by a final IPA clean.\u003c\/p\u003e\n \u003cp\u003eApply the sealant to one surface by holding the gun at a 45-degree angle and pushing the bead forward, then immediately combine the two surfaces. Uncured sealant can be cleaned up using an organic solvent such as mineral spirits.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"H.B Fuller","offers":[{"title":"Single","offer_id":46057578922176,"sku":"170300002","price":9.8,"currency_code":"AUD","in_stock":true},{"title":"Box of 20","offer_id":45216519749824,"sku":"170300002-PACK20","price":176.4,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0507\/3630\/0224\/files\/h-b-fuller-fulasealpro-840ns_733b8925-0c70-4512-99a6-148c27b93261.jpg?v=1791365882"}],"url":"https:\/\/adheseal.com.au\/collections\/h-b-fuller.oembed","provider":"Adheseal","version":"1.0","type":"link"}
