Crys-Talc® 4H

Crys-Talc® 4H by Magris Performance Materials is a high purity, high brightness, platy, medium size talc used in interior and exterior coating formulations to reduce hard settling; improve sag resistance and maximize prime pigment extension.

• It is used in solid color and semitransparent wood stains to prevent tannin bleed and improve gloss uniformity without introducing abrasive characteristics.
• It has a platy, hydrophobic structure used in architectural and industrial primers to improve barrier properties which impart corrosion resistance and stain blocking ability.
• It can also be used in polymer applications for improving stiffness, HDT, and dimensional stability in natural color applications requiring higher brightness.
• It may also be used in rigid packaging, appliances, and thermoformed products to increase the modulus of elasticity, modulus of rupture, and HDT.
• It helps reduce water diffusion, weight gain, swelling in water, loss of elasticity, and rupture modulus in moist environments.
• Crys-Talc® 4H also improves warpage resistance, creep resistance, dimensional stability, and elastic recovery.
