Abstract
This invention relates to a room temperature curing composition for use in various coatings for interior and exterior sidings, automotive bodies, household electrical appliances and plastic substrates and particularly for coatings required to have weather resistance and durability. The room temperature curing composition of this invention comprises an emulsion obtained by a multi-stage polymerization of monomers, said emulsion comprising emulsion particles, the core of which is formed by polymerization of (A) a silyl group-containing vinyl monomer, (B) an alkyl or cycloalkyl methacrylate whose alkyl moiety contains not less than 4 carbon atoms, and (C) a non-hydrophilic vinyl monomer other than (B) and the outer shell of which is formed by polymerization of (A), (B), (C) and (D) a hydrophilic vinyl monomer. The room temperature curing composition of this invention features a high stability of silyl groups it contains and a remarkably improved film-forming property even after prolonged storage. Moreover, it is very satisfactory in mechanical stability, water resistance, durability and white enamel gloss.
