Polynt POLYCOR® 99C Series (White or Colors) Casting Gel Coat
Categories: Polymer; Thermoset

Material Notes: POLYCOR® gel coats are high performance products formulated for the Casting Industry. These gel coats have lower volatile organic compounds (VOC) than conventional gel coats. POLYCOR® gel coats meet the EPA National Emission Standards for Hazardous Air Pollutants (NESHAP): Reinforced Plastic Composites Production. While offering lower VOC’s, 99C gel coats have retained the important construction application qualities customers have come to expect from Polynt Composites gel coats, such as resistance to porosity, tearing, and color separation, sag resistance, consistent liquid properties, good patchability, and more. These all add up to higher quality appeal in FRP parts made from Polynt’s 99C Series gel coats. The 99C’s are formulated to be resistant to water and certain chemicals. These gel coats were primarily developed for casting applications. These gel coats provide durable, reduced maintenance products. These gel coats require only the addition of the proper amount of the appropriate methyl ethyl ketone peroxide to cure.
