FLOCKABLE STABILITY MIXED-PHASE PIGMENTS WITH RUTILE STRUCTURE, METHOD FOR THEIR PRODUCTION AND THEIR USE

摘要

Coated rutile mixed phase pigments comprise a mixed phase rutile pigment having a first coating of an oxide or hydrated oxide of titanium, zirconium, tin or a mixture thereof and a subsequent coating of an oxide or hydroxide of aluminum, and those pigments exhibit an improved tendency against flocculation in lacquers hardened with acid catalysts.
