SINGLE-COMPONENT SYSTEM BASED ON COREACTIVE LATEX CONDUCTING COATINGS WITH AMBIENT TEMPERATURE AND POST-CROSS-LINKABLE THERMAL TREATMENT AND THEIR APPLICATION IN THE FIELD OF COATINGS

摘要

P The present invention relates to a single-component system based on coreactive latexes, capable of leading to coatings crosslinkable at room temperature and post-crosslinkable by heat treatment, said system being constituted by the mixture of two dispersions of particles, (A ) and (B), each obtained by emulsion polymerization in aqueous medium of a composition of monomers A and B respectively, (a) at least one ethylenically unsaturated monomer which can be polymerized by the radical route, comprising an incoming (CF DRAWING IN BOPI) in the composition of monomers A; and (b) at least one ethylenically unsaturated monomer which can be polymerized by the radical route, comprising an aldehyde or masked aldehyde functional group chosen from acetal, mercaptal, mercaptol, dioxolane and dithiolane, used in the composition of monomers B. /P
