Material Notes:
Gel Talc and Body Filler talc products are produced from high purity ore. Gel Talc and Body Filler products provide an excellent balance of color and mechanical properties for primary use in polyester compounds where consistent viscosity is critical and inherent low oil absorption provides higher filler loadings. Gel Talc and Body Filler talcs are platy, hydrophobic and non-abrasive.Gel Talc is specifically designed for gel coats where excellent color, predictable viscosity and superior surface characteristics are required.Information provided by Cimbar Performance Minerals.
