FINELY PARTICULATE COMPOSITE LATICES AND USE THEREOF IN SOLVENT-FREE PAINTS

摘要

Finely particulate composite latices free of non-polymeric surfactants and solvents may be prepared by the radical polymerisation of mixtures of hydrophobic monomers, e.g., styrene and an acrylic ester in emulsion in a solution of a low molecular weight copolymer such as a styrene/maleic anhydride copolymer. Said latices have a wide variety of uses, e.g. in leather processing; paints and surface coatings for wood; paints and particularly solvent-free paints for concrete, cement, plaster, roof tiles and metals; overprint inks and varnishes; adhesives for floor tiling; cement and mortar admixtures; non-pigmented coatings for leather, wood, metals and plastics; and paper sizing agents.
