This makes it ideal for marine construction, timber bonding and composite fabrication in warm Australian climates. When mixed at the recommended ratio with 105 Resin, it produces a strong, moisture-resistant epoxy system with excellent durability and structural integrity. Compared to fast or standard slow hardeners, 209 Extra Slow reduces exotherm in large batches and supports improved laminate consolidation. Trusted by professional boat builders and fabricators, it delivers reliable performance where extended working time is essential.\u003c\/p\u003e\n\u003ch3\u003eFeatures \u0026amp; Benefits\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eKey Features\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eExtra slow cure epoxy hardener\u003c\/li\u003e\n\u003cli\u003eDesigned for West System 105 Resin\u003c\/li\u003e\n\u003cli\u003eExtended open and working time\u003c\/li\u003e\n\u003cli\u003eHigh-strength structural performance\u003c\/li\u003e\n\u003cli\u003eSuitable for warm climate applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eKey Benefits\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eAllows maximum time for complex laminations\u003c\/li\u003e\n\u003cli\u003eReduces heat build-up in large mixes\u003c\/li\u003e\n\u003cli\u003eImproves fibre wet-out and consolidation\u003c\/li\u003e\n\u003cli\u003eProvides durable, moisture-resistant bonds\u003c\/li\u003e\n\u003cli\u003eIdeal for large marine and composite projects\u003cbr\u003e\u003cbr\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003e\u003cstrong\u003eTechnical Specs\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eProduct Type: Epoxy hardener – Part B\u003c\/li\u003e\n\u003cli\u003eSystem: West System 209 Extra Slow\u003c\/li\u003e\n\u003cli\u003eCompatibility: West System 105 Resin\u003c\/li\u003e\n\u003cli\u003eMix Ratio: As specified by manufacturer\u003c\/li\u003e\n\u003cli\u003eProduct Code: WS209ESH\u003cbr\u003e\u003cbr\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003e\u003cstrong\u003eKey Applications\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eLarge marine laminations\u003c\/li\u003e\n\u003cli\u003eBoat building in warm climates\u003c\/li\u003e\n\u003cli\u003eComposite structural fabrication\u003c\/li\u003e\n\u003cli\u003eTimber bonding and joinery\u003c\/li\u003e\n\u003cli\u003eIndustrial assembly requiring extended open time\u003cbr\u003e\u003cbr\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eWest System 209 Extra Slow Hardener (WS209ESH) FAQs\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eQ1: What is West System 209 Extra Slow Hardener (WS209ESH) used for?\u003c\/strong\u003e\u003cbr\u003e\u003cstrong\u003eA:\u003c\/strong\u003e It is used with West System 105 Resin to create an epoxy system with extended working time.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ2: How does 209 Extra Slow differ from 206 Slow?\u003c\/strong\u003e\u003cbr\u003e\u003cstrong\u003eA:\u003c\/strong\u003e It provides even longer open time, making it ideal for hot climates and large laminations.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ3: Can this hardener be used on its own?\u003c\/strong\u003e\u003cbr\u003e\u003cstrong\u003eA:\u003c\/strong\u003e No, it must be mixed with West System 105 Resin to cure properly.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ4: Is this suitable for marine applications?\u003c\/strong\u003e\u003cbr\u003e\u003cstrong\u003eA:\u003c\/strong\u003e Yes, it is widely used in boat building and marine structural work.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ5: Does it maintain structural strength?\u003c\/strong\u003e\u003cbr\u003e\u003cstrong\u003eA:\u003c\/strong\u003e Yes, when mixed correctly it produces a strong, moisture-resistant epoxy bond.\u003cbr\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003ch3\u003eDownloads\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0785\/1937\/0022\/files\/West209-SDS.pdf?v=1770905151\" target=\"_blank\" rel=\"noopener noreferrer\"\u003eSafety Data Sheet (SDS)\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"West System","offers":[{"title":"1.33L","offer_id":53249479541030,"sku":"WEST209","price":175.42,"currency_code":"AUD","in_stock":true},{"title":"330ml","offer_id":53249479573798,"sku":"LAWE-H-B-209","price":56.58,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0785\/1937\/0022\/files\/west-system-209-extra-slow-hardener.jpg?v=1779873087","url":"https:\/\/ritepriceindustrial.com.au\/products\/west-system-209-extra-slow-hardener","provider":"Rite Price Industrial Coatings \u0026 Supplies","version":"1.0","type":"link"}
