Crys-Talc® 4H-4HC is a high-purity, high-brightness, platy, medium-sized talc used in interior and exterior coating, adhesive, and sealant formulations to reduce hard settling, improve sag resistance, and maximize prime pigment extension. Crys-Talc® 4H is used in solid-color and semitransparent wood stains to prevent tannin bleed and improve gloss uniformity without introducing abrasive characteristics. Crys-Talc® 4H has a platy, hydrophobic structure used in architectural and industrial primers to improve barrier properties which impart corrosion resistance and stain blocking ability.
