  • PAINT-PROTECTIVE COATING MATERIAL AND ACRYLIC COATING COMPOSITION
    Publication number: 20220363940
    Abstract: Provided is a paint-protective coating material formed from an acrylic coating composition comprising an acrylic polymer as base polymer. The acrylic polymer-forming monomers includes a monomer (mT) having a homopolymer Tg of 90° C. or higher and a monomer (mL) having a homopolymer Tg of ?30° C. or lower. The monomer (mT) includes at least acrylonitrile. In the monomers, the monomers (mT) and (mL) have a molar ratio (mT/mL) of 0.8 or higher and 1.5 or lower. The paint-protective coating material has storage moduli of 150 MPa or higher and 1000 MPa or lower at 23° C., and 0.40 MPa or higher at 70° C.
