Aluminum Silicate OPTISIL PS20 25/1
ALUMINUM SILICATE OPTISIL PS20 25/1 is the best extender for titanium dioxide, possessing excellent opacity and high whiteness. By partially replacing titanium dioxide, it increases efficiency and reduces costs. Thanks to its super fine particle size and excellent anti-settling property, it imparts a good brightening effect to coatings. Its good stability against acid and alkali provides excellent corrosion resistance to the coating.
