Use of aqueous film-forming preparations based on copolymers of methacrylic acid alkyl esters for coating mineral shaped bodies

摘要

The present invention provides for the use of aqueous film-forming formulations comprising at least one copolymer P as film-forming constituent which is present in disperse form in the formulation and is composed of ethylenically unsaturated monomers M, the monomers M comprisingi. from 70 to 99.9% by weight of at least one ester of methacrylic acid with a C1-C10-alkanol andii. from 0.1 to 30% by weight of at least one different monoethylenically unsaturated monomerand at least 50% by weight of the monomers M being other than methyl methacrylate and not more than 1% by weight of the monomers M having two or more ethylenically unsaturated double bonds, for coating mineral moldings.The present invention additionally provides a method of coating the mineral moldings, and also the mineral moldings themselves.
