HK Research Corporation's LHA-3500 Gel Coat is based on an Isophthalic-Hybrid resin. This backbone provides the product with unique physical characteristics. Handling properties make this product almost a "drop in" in applications where higher HAP Gel Coats are now being used. These unsurpassed Gel Coat
systems provide the composites Industry with a hard stain and abrasion resistant surface. We do not recommend this product for constant water contact.
