Use of aqueous dipersion of particles made up of polymerisate and fine inorganic solid material for priming mineral substrates

摘要

Aqueous dispersions (I) of composite particles comprising a polymer and fine inorganic particulate prepared by radical polymerization of a mixture of ethylenically unsaturated monomers that contains at least one ethylenically unsaturated alkoxysilane monomer in an aqueous medium in the presence of a dispersed fine particulate inorganic solid and at least one dispersing agent are useful for the priming of mineral substrates.
