Document Type and Number:
Japanese Patent JP6540712
Kind Code:
B2
Abstract:
To provide a composition for powder coating material capable of forming a coating film having excellent water and oil repellency, capable of maintaining excellent water and oil repellency even when the surface is rubbed or when used in an environment in contact with water, and having excellent resistance to adhesion of organisms such that organisms such as mold, algae, etc. are less likely to adhere thereto; a powder coating material; and a coated article. The composition for powder coating material comprises polymer (A) composed of at least one member selected from polymer (A1) and polyvinylidene fluoride, and polymer (B). The polymer (A1) is a fluorinated non-block copolymer having units based on a fluoroolefin and units based on a monomer having a crosslinkable group. The polymer (B) is a fluorinated block copolymer having a segment (±) in which the content of fluorine atoms is at least 20 mass%, and a segment (²) in which the content of fluorine atoms is less than 20 mass%, wherein the difference in the numerical value of the content of the fluorine atoms represented by mass%, between in the segment (±) and in the segment (²) is at least 10, and at least one of the segment (±) and the segment (²) has a hydroxy group.
