AQUEOUS COATING MATERIAL COMPOSITION IMPARTING DESIGNABILITY TO OUTER WALL

摘要

PROBLEM TO BE SOLVED: To provide an aqueous coating material composition which is a one-liquid type, and keeps hydrophilic property of a coated material surface even with a coated film thickness of 0.5-6.5 mm and keeps the hydrophilic property over a long period of time, and as a result, has less adhesion of dirt on the coated material surface and imparts designability to an outer wall.;SOLUTION: An aqueous coating material composition imparting designability to an outer wall contains an acrylic resin-based emulsion, a photopolymerization initiator, an ultraviolet absorber eutectic with the photopolymerization initiator, a surface hydrophilic agent, a filler, an aggregate, a pigment, a thickener, and a film-forming auxiliary agent, where the photopolymerization initiator is 1.0-4.0 pts.wt. with respect to 100 pts.wt. of a solid content of the acrylic resin-based emulsion, and the surface hydrophilic agent is 7.5-15.0 pts.wt. with respect to 100 pts.wt. of a solid content of the acrylic resin-based emulsion, and the aqueous coating material is a one-liquid type and is coated to a base with a thickness of 0.5-6.5 mm.;SELECTED DRAWING: None;COPYRIGHT: (C)2018,JPO&INPIT
