Title:
AQUEOUS COATING MATERIAL COMPOSITION FOR SUBSTRATE ADJUSTMENT, AND SUBSTRATE ADJUSTMENT METHOD AND COATING MATERIAL FINISHING STRUCTURE USING THE SAME
Document Type and Number:
Japanese Patent JP2023018554
Kind Code:
A
Abstract:
To provide an aqueous coating material composition for substrate adjustment which is excellent in quick drying property and low temperature curability, has both water vapor permeability and water-shielding property, has sufficient elongation physical property and substrate followability, and has viscosity and a TI value suitable for construction by a roller brush.SOLUTION: An aqueous coating material composition for substrate adjustment is composed of crosslinked type acrylic resin-based emulsion having a glass transition temperature of -20 to 10°C, nano-composite emulsion in which a micelle with a particle diameter of 60-120 nm formed of an acrylic resin containing one or two or more silica particles with a primary particle diameter of 15-30 nm and an emulsifier is dispersed in water, a water-soluble cationized polymer, a volatile base, a filler, an organic thickener, a film formation auxiliary and a pigment, and has a pH of the whole composition of 9.5-11.5.SELECTED DRAWING: None
