Urethane Coatings

Urethane coatings are by far one of the most chemically resistant sealers protecting indoor and outdoor areas with high risks of exposure to chemical spills and fuel. Urethanes are commonly used in garages and warehouses, industrial facilities, aircraft hangers, auto service centers, laboratories, restaurants, food prep kitchens and exterior tanks to name a few. What makes urethane coatings, especially aliphatic urethanes the ideal solution for these applications is their abrasion resistance and durability.

By far, the longest lasting urethane, resisting the most chemicals and abrasions is Urethane 645. Urethane 645 is a 65% solids two component clear polyester/aliphatic polyurethane coating. Combining the highest quality of polyester and aliphatic polyurethanes we could source, our chemist set out to formulate an aliphatic urethane that would out last, out perform and be twice as resilient as any other aliphatic urethane on the market today. To our success Formula 645 was born and Urethane 645 was created. This formula has proven to be practically indestructible. It provides incredible abrasion resistance, chemical resistance and is UV stable. Weve created the ultimate protection for indoor and outdoor areas with high risks of exposure to chemical spills, fuel, heavy equipment, extreme temperatures and any other potentially damaging situation your substrate may encounter.
