JetWhite 4H is a high purity, high brightness, platy, medium size talc used in interior and exterior coating, adhesive and sealant formulations to reduce hard settling; improve sag resistance and maximize prime pigment extension. JetWhite 4H is used in solid color and semitransparent wood stains to prevent tannin bleed and improve gloss uniformity without introducing abrasive characteristics. JetWhite 4H has a platy, hydrophobic structure used in architectural and industrial primers to improve barrier properties which impart corrosion resistance and stain blocking ability. JetWhite 4H can also be used in polymer applications for improving stiffness, HDT, and dimensional stability in natural color applications requiring higher brightness. It is used in polyethylene, polypropylene, PVC, and other plastic based applications to achieve maximum stiffness and is available in densified or compacted form to improve feeding, enhance extrusion throughput, and reduce dusting. JetWhite 4H may also be use in rigid packaging, appliances, and thermoformed products to: increase modulus of elasticity, modulus of rupture, and HDT; reduce water diffusion, weight gain, and swell in water, loss of elasticity and rupture modulus in moist environments; improve warpage, creep, dimensional stability, and elastic recovery.
