Abstract

A coated titanium dioxide pigment and the process for its preparation consisting essentially of a core of pigmentary titanium dioxide (TiO2), a dense inner coating of dense amorphous silica (SiO2) in an amount from 1% to 10% by weight, based on the uncoated pigment, and, optionally, up to 5% of alumina (Al2O2) and a porous outer coating of porous silica (SiO2) and alumina (Al2O3), said porous silica being present in an amount from 0.5% to 15% by weight and said alumina being present in an amount from 0.5% to 11% by weight, based on the uncoated pigment. As a component of coating compositions, this pigment provides a high degree of hiding power and durability for indoor and outdoor applications. [CA1053087A]
