White Powder Corrosion Pigment Silica Dioxide for Auto-Motive Coatings


Product Description


SKYSIL® AC-20 silica is suggested for use primarily in coatings applied to galvanized steel and related substrates such as zinc alloy coated steels where the zinc alloy contains low amounts of aluminum or magnesium. Recommended application areas include coil coating primers, general industrial primers and primers for auto- motive coatings. SKYSIL® AC-20 silica is also suitable for use in single layer coatings applied over metal sub- strates and in the so-called primer-pretreatment coatings.
