RAW MATERIALS
Lintalc EW 20 is made of pure lamellar talc. The crystals are macro crystalline in shape and processed in such a way so as to always retain this shape. This filler has an extremely high degree of whiteness and chemical purity. Lintalc EW 20 renders these unique properties it possesses wherever it is applied.
