Zinc oxide CR-41 Zinc oxide G. H. Chemicals Filler >> Zinc oxide Special effect pigments >> Fluorescent Whitening Agent/ Optical brithener Coatings >> Solventborne Coatings >> Waterborne Insoluble in water, solvents and neutral oils Soluble in strong acids and alkalis French Process zinc oxide is a white, odourless powder possessing high brightness, a high refractive index and a relatively fine particle size. Zinc oxide is insoluble in water, solvents and neutral oils. Zinc oxide is soluble in both strong acids and alkalis. Zinc oxide has a chemical properties which impede the growth of fungi, mildew and mold. Paints and Coatings Zinc oxide is used in both water and solvent based formulations. Zinc oxide can be used as a pigment as well as an excellent brightener. Zinc oxide is also an additive which absorbs UV rays to extend colour retention. Zinc oxide is an excellent inhibitor of fungi, mildew and mould. White, odourless zinc oxide. Used as a pigment and very good brightener in water and solvent based paints and coatings. Possesses high brightness, high refractive index and relatively fine particle size. Can be used as an additive which absorbs UV rays to extend colour retention and as a very good inhibitor of fungi, mildew and mould.
