HAPCOAT 3726

HAPCOAT 3726 is a high heat resistant, thixotropic, gel coat that is specifically designed to reproduce surface details exactly and eliminate print through. When HAPCOAT 3726 is used with HAPCURE 7 curing agent, it is ideally suited for molds filled with aluminum conductites or sand, or backed with fiberglass cloth. This is due to its fast "tack-up" time which eliminates any print through.

• Formulated to withstand 350°F continuous service, & intermittent service to 400°F

• Being thixotropic, HAPCOAT 3726 applies easily with a brush, and will not sag when applied to a vertical surface

• Easily machined and can be drilled, tapped, or milled with conventional tools

• When used with HAPCURE 7, HAPCOAT 3726 reaches "tacked-up" (bubble gum) state in approximately 30-45 minutes.

• Short-term exposure to 400°F and continuous service to 350°F is possible with this system.

• Reproduces the finest surface detail and texture.

• There is almost no shrinkage during cure with HAPCOAT 3726.

• May be used with a variety of curing agents to accommodate a wide range of application requirements.
