It’s supplied in a 4 oz (≈113 g) tube for convenient dispensing and mix-to-use hardening.\u003cbr\u003eK-Bond Hardener Tube is a 4 oz tube of methyl ethyl ketone peroxide (MEKP) hardening agent formulated to catalyze and cure K-Bond polyester adhesives used in stone fabrication and repair. When mixed with K-Bond polyester resins at the correct ratio, this hardener initiates rapid polymerization, transforming the liquid resin into a solid bond or fill suitable for seaming, laminating, chip filling, and edge repair on natural and engineered stone. It is metered for consistent cure and is compatible with most K-Bond polyester adhesive systems. \u003c\/p\u003e\n\u003ch2 data-section-id=\"1ma7m6t\" data-start=\"988\" data-end=\"1003\"\u003e\u003cbr\u003e\u003c\/h2\u003e\n\u003ch2 data-section-id=\"1ma7m6t\" data-start=\"988\" data-end=\"1003\"\u003eKey Features\u003c\/h2\u003e\n\u003ch3 data-section-id=\"3u2fmh\" data-start=\"1004\" data-end=\"1028\"\u003ePerformance Features\u003c\/h3\u003e\n\u003cp data-start=\"1029\" data-end=\"1524\"\u003eMEKP hardener for polyester adhesives: Designed specifically to cure K-Bond polyester resin systems. \u003cbr\u003e4 oz tube: Convenient size for typical shop use with small batches of adhesive. \u003cbr\u003eFast cure initiation: Helps polyester resin gain strength and reach workable cure time. \u003cbr\u003eMetered dosing: Ensures more consistent curing performance when mixed correctly. \u003cbr\u003eUsed in stone fabrication: Ideal for preparing polyester adhesives used on granite, marble, quartz and similar materials.\u003c\/p\u003e\n\u003ch2 data-section-id=\"1a3ueyz\" data-start=\"1525\" data-end=\"1542\"\u003e\u003cbr\u003e\u003c\/h2\u003e\n\u003ch2 data-section-id=\"1a3ueyz\" data-start=\"1525\" data-end=\"1542\"\u003eSpecifications\u003c\/h2\u003e\n\u003ch3 data-section-id=\"1o2c85r\" data-start=\"1543\" data-end=\"1562\"\u003eProduct Details\u003c\/h3\u003e\n\u003cp data-start=\"1563\" data-end=\"2190\"\u003eBrand: K-Bond\u003cbr\u003eModel \/ SKU: HARD-70051\u003cbr\u003eProduct Type: Polyester Hardener Tube (BPO hardener)\u003cbr\u003eWeight \/ Size: Approx. 4 oz (≈0.2 lb \/ 113 g)\u003cbr\u003eForm: Paste (BPO dispersed in carrier for easy use)\u003cbr\u003eChemical Base: Benzoyl Peroxide (BPO) catalyst\u003cbr\u003eUsage: Catalyst for curing polyester adhesives\/resins in stone, composite, and repair work\u003cbr\u003eApplication Method: Mixed directly into resin\/adhesive per product instructions\u003cbr\u003eHazard Classification: DOT-regulated as hazardous material for transportation; special handling\/return rules may apply.\u003cbr\u003eTypical Industries: Stone fabrication, engineered stone bonding, composite repair, laminating\u003cbr\u003e \u003c\/p\u003e\n\u003ch2 data-section-id=\"5rwgr3\" data-start=\"2191\" data-end=\"2206\"\u003eTypical Uses\u003c\/h2\u003e\n\u003ch3 data-section-id=\"xx0hya\" data-start=\"2207\" data-end=\"2230\"\u003eCommon Applications\u003c\/h3\u003e\n\u003cp data-start=\"2231\" data-end=\"2488\" data-is-last-node=\"\" data-is-only-node=\"\"\u003eK-Bond HARD-70051 (hardener tube) is used together with K-Bond polyester adhesives for:\u003cbr\u003e✔ Seaming stone countertops\u003cbr\u003e✔ Laminating slabs or edge pieces\u003cbr\u003e✔ Filling chips, cracks, and voids\u003cbr\u003e✔ General stone bonding and repair work on natural and engineered stone.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"z-0 flex min-h-[46px] justify-start\"\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003cdiv class=\"mt-3 w-full empty:hidden\"\u003e\n\u003cdiv class=\"text-center\"\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/article\u003e\n\u003c\/div\u003e\n\u003cdiv aria-hidden=\"true\" data-edge=\"true\" class=\"pointer-events-none h-px w-px absolute bottom-0\"\u003e\u003cbr\u003e\u003c\/div\u003e","brand":"Kbond","offers":[{"title":"Default Title","offer_id":51210011115736,"sku":"HARD-70051","price":4.23,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0724\/5407\/8680\/files\/kbond-default-title-k-bond-bpo-4-oz-hardener-tube-39847663141080.jpg?v=1781059258","url":"https:\/\/bladerunnerdiamondtools.com\/products\/k-bond-bpo-4-oz-hardener-tube","provider":"Bladerunnertools","version":"1.0","type":"link"}
