Abstract

The present invention provides a metal powder directional resin composition comprising polymer and solvent, wherein the polymer comprises following monomers as polymerization units: (a) a methyl methacrylate monomer; (b) a monomer with a high glass-transition temperature; and (c) a monomer with a low glass-transition temperature, wherein, weight-average molecular weight of the polymer is at least about 50000. The metal powder directional resin composition of the present invention has a significant effect for direction arrangement of metal power, and can be used in metallic paint. In addition, the metal powder directional resin composition has the advantages of good water resistance and good alcohol resistance, perfect compatibility with other resin, capacity for showing higher brightness and metal mirror effect.

Description

technical field [0001] The present invention relates to a metal powder oriented resin composition, in particular to a metal powder oriented resin composition which can be used in metal coating compositions. Background technique [0002] Metal polishing of automobiles is usually done by pretreating steel sheets such as zinc phosphate, and then coating them with metal coatings, followed by wet-on-wet coating of clear coatings on top, and then baking the two coats together to form. [0003] Known metallic paints, such as metallic paints or also known as silver powder paints, refer to paints doped with aluminum powder to make the painted car body or 3C electronic product surface bright, and at different angles, Due to the reflection of light, the color appearance of the car body or 3C electronic products looks richer and fuller. However, the aluminum powder used in general metallic paint or silver powder paint has a flake-like structure and is irregularly arranged in the paint...
