Patent

CA 2237388

A TiO2 pigment particle having a surface coating of inorganic particles or mineral particles exhibiting improved light scattering efficiency of TiO2 at a moderate to high pigment volume concentration (PVC) and a low oil absorption when incorporated in coatings applications is disclosed, and methods of accomplishing the same.

L'invention concerne une particule de pigment de TiO¿2? comportant une couche protectrice constituée de particules inorganiques ou minérales. Ces particules présentent une dispersion de la lumière du TiO¿2? plus efficace à une concentration pigmentaire volumique (PVC) modérée à forte, et une prise d'huile faible quand elles sont incorporées dans des revêtements. L'invention concerne également les procédés de réalisation associés.
