 Character: As a non - toxic white powder, insoluble in water and acid decomposition produce hydrogen sulfide, have no effect with hydrogen sulfide    andalkali .  Its heat resistance is good, it can improve weather, prevent algae, reducing costs and the whiteness with excellent covering power.

Application: Can be applied to all paint, coatings, Thermoplastic and thermosetting plastics and paper. Such as coating, paint, paint, inks, plastics, rubber, paper, enamel, leather, and so on
