Titanium pigments trends

Pigment Brown 45 (MnWTi). As it has become apparent that antimony is not bio-available from doped rutiles, the trend for such substitutions with respect to food contact applications has strongly diminished. A more scientific survey on colored titanium MMO pigments is given by Maloney [3.93]. 

Pigments commonly used are titanium dioxide and extender pigments. Special lead-containing pigments e.g. silicates are used as anticorrosive agents. Lead also catalyzes the curing reaction, however the trend nowadays is eliminate lead from electrocoat. Solvent content is low (typically less than 2 % based on total volume). The solids content is ca. 20 %.
