Lihat Profil SellerPremium uncoated CaCO₃ powder with D50 7.5µm for superior dispersibility and cost efficiency
KT 75 is a high-purity, uncoated calcium carbonate powder manufactured by PT. Supersonic Chemical Industry from premium white limestone. With a median particle size of 7.5 ± 1.0 µm and top cut of 70 ± 10 µm, it delivers excellent flowability and dispersion for demanding industrial applications. Ideal for matte emulsion paints, plastics, rubber, paper, glass, and porcelain, KT 75 enhances opacity, gloss control, mechanical strength, and surface finish while reducing formulation costs. Rigorously tested to ISO standards for brightness, whiteness, moisture, and chemical purity.
