Abstract

La présente invention concerne des formulations de revêtement améliorées contenant des agents matifiants à base de silice sous la forme d'un mélange de particules de silice à faible volume de pore et de particules de silice à haut volume de pore. Les formulations matifiantes sont utiles dans les compositions de revêtement aqueuses pour fournir des propriétés exceptionnelles à un substrat revêtu. Les films résultant des formulations de revêtement contenant les agents matifiants à base de silice sur un substrat fournissent de manière inattendue une résistance chimique améliorée à la surface du substrat, en particulier au bois ou aux matières plastiques. L'invention concerne également des procédés de fabrication et d'utilisation des formulations matifiantes à base de silice.
