Low Emissions White Gel Coat

What Is #683 Low Emissions White Gel Coat?

#683 Low Emissions White Gel Coat is a highly durable low-emissions ISO gel coat and the industry production standard for molding applications. #683 provides superior performance in critical-use environments with outstanding cosmetics and exceptional in-process application properties, and is engineered to spray well in fabrication, particularly where tapelines are critical.

Why Choose #683 Low Emissions White Gel Coat?

#683 Low Emissions White Gel Coat is the production-standard white for good reasons: proven performance where high UV protection, excellent blister resistance, or excessive ambient temperatures are factors. #683 can be used as a sandable base coat for painting or polished to a high-luster finish, which gives flexibility in how the part is finished. It is also the white base for #710 Color Gel Coat, underpinning the entire Fibre Glast color program.

What Are the Best Applications for #683 Low Emissions White Gel Coat?

#683 Low Emissions White Gel Coat is designed as the production white surface coat for molded polyester or vinyl ester parts, as a sandable base for paint, or as the base for #710 Color Gel Coat. It suits parts needing strong UV and blister resistance or that cure in high ambient temperatures.

How Should #683 Low Emissions White Gel Coat Be Used for Best Results?

#683 Low Emissions White Gel Coat is catalyzed at about 2% MEKP depending on ambient temperature. Spray unthinned into molds with a cup gun, or blend with #1040 Duratec® Clear Hi-Gloss Additive when performing repairs. One gallon covers approximately 40 to 80 square feet. Use as a sandable base for paint or polish to a high luster.
