Abstract
PURPOSE: To improve adhesion between a coating film and a solid substrate, by using a specified organoalkoxysilane as a modifier in the formation of a rigid coating film by coating a polyurethane water paint on a solid substrate.
CONSTITUTION: In the formation of a rigid coating film by coating a polyurethane water paint for rigid film formation on a solid substrate, and org. solvent soln. of an organoalkoxysilane compd. of the formula (wherein X is mercapto, amino, epoxy; R1 is a 1W4C alkylene; R2 is a 1W4C alkyl) such as γ-mercapto- propyltrimethoxysilane is previously coated on the solid substrate and dried, and then said polyurethane water paint is coated thereon. Alternatively, said organoalkoxysilane compd. is blended with said polyurethane water paint. In this way, adhesion between the resulting coating film and said solid substrate can be improved.
