HYDROPHOBIC SUBSTRATES AND METHODS FOR THEIR PRODUCTION USING ACYLOXYSILANES

A method for rendering a substrate hydrophobic includes treating the substrate with an acyloxysilane. The treatment includes impregnating the substrate with an acyloxysilane and thereafter curing (hydrolyzing and condensing the acyloxysilane) to form a silicone resin. The method is particularly usef...

Zusammenfassung:	A method for rendering a substrate hydrophobic includes treating the substrate with an acyloxysilane. The treatment includes impregnating the substrate with an acyloxysilane and thereafter curing (hydrolyzing and condensing the acyloxysilane) to form a silicone resin. The method is particularly useful for rendering paper hydrophobic. L'invention concerne un procédé pour rendre un substrat hydrophobe qui inclut le traitement du substrat avec un acyloxysilane. Le traitement inclut l'imprégnation du substrat avec un acyloxysilane et après cela le durcissement (par hydrolyse et condensation de l'acyloxysilane) pour former une résine de silicone. Le procédé est particulièrement utile pour rendre du papier hydrophobe.
