Resins are essential in boat building and repairs and are used for base coat applications and saturating composite fabrics. Thus, it’s crucial to use only premium- quality laminating resins for your projects. If that's what you're looking for, then we have what you need — a resin that’s easy to apply and allows for strong adhesion. Plus, since it's a general-purpose product, its use isn't just limited to boats and watercrafts. Get top-notch results for your construction and repair jobs with Polymer World’s Polyester Resin with MEK-P Hardener with our chopped strand mat. This fast-wet-out laminating resin can be applied to any fiberglass surface. This includes target areas on boats and yachts, as well as surfboards and kayaks. They can also be used for car and motorcycle parts and even plumbing fixtures like fiberglass bathtubs. Tired of resins that cure very quickly? Not a problem — our polyester resin stays tacky and won't cure as rapidly as others. You don't have to worry about it hardening while you're in the middle of the job. When it does cure, it results in secure adhesion, ensuring that every layer you stacked is well-bonded. What's more, our 1-gallon jug of laminating resin comes with a 2-fl oz bottle of MEK-P catalyst and our chopped strand mat. You can adjust the amount of hardener you add to the resin to control the gel time. When handling this resin, we recommend doing so in temperatures between 70-95°F for optimal results. When not in use, we suggest storing it in areas with temperatures below 77°F. Here are more details about our laminating resin: - Easy to mix, superb consistency - Doesn't contain wax - Marine-grade and waterproof ## Features - ✅ From Water crafts to Bath Fixtures - Upgrade your building and repair kit with our general-purpose marine fiberglass resin. You can confidently use it on a boat, surfboard, automobile, and even a bathtub - ✅ Convenient Application - This fiberglass boat repair kit allows for fast wet out. Easy to spread, the wetting resin impregnates fibrous material quickly and can be applied using spray-ups or hand layups. - ✅ Excellent Tackiness - Our fiberglass resin stays tacky for a longer period. This makes it easier for you to apply stacks or layers of reinforcement materials, which then allows for stronger adhesion. - ✅ Cleaner Results- With its superior formula, this fibre glass resin won't sag or flow when applied to sloping surfaces. The marine resin also helps minimize pattern print-throughs on gelcoat finishes. - ✅ Complete Your Marine Fiberglass Repair Kit for Boats - The 1- gallon polyester resin includes a 2 fl oz bottle of MEK-P polyester resin catalyst. No need to buy a resin hardener separately. - ✅ Our Florida Based business has well over 7 years of experience in the boating industry, and we are just getting started.
