Title:
AQUEOUS COATING MATERIAL COMPOSITION, METHOD FOR FORMING COATING FILM, AND METHOD FOR FORMING MULTILAYER COATING FILM
Document Type and Number:
WIPO Patent Application WO/2024/018708
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide an aqueous coating material composition which exhibits excellent storage stability and can form a coating film having excellent abrasion resistance, chipping resistance and adhesion to glass even if cured at a relatively low temperature. This aqueous coating material composition contains: an aqueous dispersion of particles of a urethane resin (A) obtained from a compound (a1) having a secondary amino group and an alkoxysilyl group and an isocyanate group-containing urethane prepolymer (a2); and a curing agent (B). The aqueous coating material composition is characterized in that: the compound (a1) having a secondary amino group and an alkoxysilyl group is obtained from constituent components including a compound (a11) containing a primary amino group and an alkoxysilyl group and a polymerizable unsaturated group-containing compound (a12); and the content of the curing agent (B) falls within the range 5-50 mass% relative to the total amount of solid resin content in the aqueous coating material composition.
