Document Type and Number:
WIPO Patent Application WO/2024/075612
Kind Code:
A1
Abstract:
Provided are a coating composition that has an excellent film-forming property in a low-temperature environment and can form a coating film having excellent adhesiveness to concrete materials, and a coated article. The coating composition of the present invention contains a fluoropolymer, a (meth)acrylic polymer, and water, wherein the particle size of the (meth)acrylic polymer in the coating composition is 150 nm or more, the glass transition temperature of the (meth)acrylic polymer is 40°C or less, the minimum film formation temperature of both the fluoropolymer and the (meth)acrylic polymer is 50°C or less, the absolute value of the difference between the minimum film formation temperature of the fluoropolymer and the minimum film formation temperature of the (meth)acrylic polymer is 20°C or less, and the absolute value of the difference between the particle size of the fluoropolymer and the particle size of the (meth)acrylic polymer is 35 nm or less. Furthermore, the minimum film formation temperature of the fluoropolymer may be 60°C or less.
