Abstract
The purpose of the present invention is to provide a coating composition for outer walls and building exteriors, which gives a substrate water repellency, water resistance, rain streak stain resistance, stain resistance, and weather resistance; and an article, a building material for outer walls and building exteriors, each having a coating formed from the aforesaid coating composition. The present invention provides a coating composition for an outer wall or exterior of building, wherein the coating composition comprises the following components (A) to (D): (A) an emulsion of a silicone acrylic copolymer resin which is a copolymer of 60 to 99 parts by mass of (a1) a polyorganosiloxane represented by the formula (1) and 1 to 40 parts by mass of (a2) an acrylic acid ester monomer and/or a methacrylic acid ester monomer, provided that a total amount of components (a1) and (a2) is 100 parts by mass, the emulsion being in an amount of 0.5 to 20 parts by mass as a solid content, (B) at least one resin emulsion in an amount of 20 to 80 parts by mass as a solid content, selected from the group consisting of acrylic resin emulsions other than component (A), urethane resin emulsions and alkyd resin emulsions, (C) pigment in an amount of 1 to 50 parts by mass, and (D) a flame retardant in an amount of 1 to 10 parts by mass, provided that a total mass of the solid contents of components (A) and (B) and the amounts of components (C) and (D) is 100 parts by mass.
