Use of aqueous dispersions of addition polymer and finely divided inorganic solid to prime mineral substrates

摘要

Aqueous dispersions of composite particles composed of addition polymer and finely divided inorganic solid and obtainable by free-radical emulsion polymerization on a mixture of ethylenically unsaturated monomers including at least one ethylenically unsaturated alkoxysilane monomer in an aqueous medium in the presence of a dispersely distributed, finely divided inorganic solid and at least one dispersant are used to prime mineral substrates. Aqueous dispersions obtainable by blending an addition polymer obtainable by free-radical emulsion polymerization of a mixture of ethylenically unsaturated monomers including at least one ethylenically unsaturated alkoxy silane monomer in an aqueous medium with a dispersely distributed, finely divided inorganic solid in the presence of at least one dispersant are used to prime glasslike substrates.
