The kit mixes 1 pint of Part A with 1 pint of Part B to produce about 0.375 cubic feet of closed-cell foam that can be laminated over with polyester, epoxy or vinyl ester resins once cured. It is especially useful where controlled, in-place pouring and a moderate 6LB density are required.\u003c\/p\u003e\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eTwo-part formulation:\u003c\/strong\u003e Equal parts of Part A and Part B are mixed and poured to create a consistent closed-cell foam that provides buoyancy and insulation.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e6LB density:\u003c\/strong\u003e The mid-weight foam balances rigidity and carvability, making it suitable for flotation, decoys and sculpting projects.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eQuart kit yield:\u003c\/strong\u003e The 1 pint + 1 pint kit produces approximately 0.375 cubic feet of cured foam, convenient for small repairs and fills.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eResin compatible:\u003c\/strong\u003e Once fully cured the foam accepts polyester, epoxy or vinyl ester laminates without melting, allowing reinforcement or fairing.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFast working profile:\u003c\/strong\u003e Working time before foaming is about 45 seconds with full expansion around 5 minutes at recommended temperatures, enabling quick turnarounds.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTemperature sensitive:\u003c\/strong\u003e Best performance between 75 and 80 F; lower temperatures reduce expansion and may require more material.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eWho It's For\u003c\/h2\u003e\n\u003cp\u003eThe kit is aimed at boaters, dock builders, hobbyists and modelers who need reliable buoyancy or a carvable closed-cell foam for decoys, taxidermy, filling voids and soundproofing. Its small yield and compatibility with common marine resins make it practical for patching cavities or creating lightweight floatation blocks where larger drums would be wasteful.\u003c\/p\u003e\n\u003cp\u003eIt is less suitable for very large displacement flotation jobs that require bulk quantities or for users who cannot reliably control ambient temperature during mixing, since expansion rates and final yield are temperature dependent.
