This resin is a marine-grade, low viscosity polyester laminating resin supplied with MEKP hardener and formulated to stay tacky longer so layers can be positioned and stacked more easily. The single biggest reason to buy is the combination of professional-grade cure behavior and included catalyst bottles, which saves trips for separate hardener purchases and simplifies small-to-large projects.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMarine Grade Quality:\u003c\/strong\u003e The resin is described as GRADE A and intended for marine and RV manufacturers, giving confidence for structural repairs and new builds.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded MEKP Hardener:\u003c\/strong\u003e Each gallon ships with a 2oz bottle of MEKP, so users have the correct catalyst on hand for immediate mixing and curing.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExtended Tack Time:\u003c\/strong\u003e The formula offers longer tackiness, which helps when stacking multiple layers of mat, biaxial or cloth without early skinning.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLow Viscosity Coating:\u003c\/strong\u003e Low viscosity allows excellent wet-out of fiberglass and coring materials, making hand layups and spray application easier.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCures Tack Free Without Wax:\u003c\/strong\u003e The ortho-type polyester cures fully in 24-36 hours without wax under typical conditions, allowing subsequent lamination or gelcoat adhesion.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eWho It's For\u003c\/h2\u003e\u003cp\u003eThis resin is aimed at professional boatbuilders, repair shops and experienced DIYers who work on boats, kayaks, canoes, surfboards, RVs and automotive fiberglass parts and need a reliable polyester laminating resin.
