Title (EN) SILICA-BASED MATTING AGENTS AND METHODS OF MAKING AND USING THE SAME
(FR) AGENTS DE MATITÉ À BASE DE SILICE ET PROCÉDÉS DE PRÉPARATION ET D'UTILISATION DESDITS AGENTS
Abstract:
(EN) Improved silica-based matting agents are disclosed. The matting agents are useful in waterborne coatings composition to provide exceptional properties to a wood based substrate. Films resulting from the silica-based matting agents on a wood substrate unexpectedly provide improved chemical resistance and/or film clarity to the surface of the wood substrate. Methods of making and using the matting agents are also disclosed.
(FR) L'invention concerne des agents de matité à base de silice améliorés. Ces agents de matité sont utiles dans des compositions de revêtement à l'eau pour conférer des propriétés exceptionnelles à un substrat à base de bois. Les films obtenus à partir des agents de matité à base de silice sur un substrat en bois fournissent, de manière inattendue, une résistance chimique et/ou une clarté de film améliorées à la surface du substrat en bois. L'invention porte également sur des procédés de préparation et d'utilisation desdits agents de matité.
