Abstract

The invention relates to a thermosetting acrylic metallic paint. The metallic paint comprises the following components: 18-23wt% of thermosetting acrylic resin, 13-16wt% of amino resin, 8-12wt% of pigments, 3.5-5.0wt% of aids and 45-60wt% of solvent. The thermosetting acrylic metallic paint has the beneficial effects that the thermosetting acrylic metallic paint has excellent adhesiveness and solvent resistance and is suitable for coating the surfaces of bicycles, motorcycles, cars, refrigerators, washing machines, electric fans, instruments, meters, precision machinery and IT products; and the coatings formed by coating the paint have bright colors, high hardness, good lusters, strong sense of metal of the metallic paint and excellent abrasion resistance, weather resistance, adhesiveness and solvent resistance.

Description

technical field [0001] The invention belongs to the technical field of coatings, more specifically, the invention relates to a thermosetting acrylic metal paint with excellent adhesion and solvent resistance. Background technique [0002] The main film-forming substances of two-component acrylic polyurethane coatings contain hydroxyl resin and polyurethane. Because of their excellent physical and mechanical properties, excellent gloss retention, color retention, and weather resistance, they are widely used in the coating of product shells with high chemical resistance. For example, the thermosetting metallic paint can be used in packaging and general industrial coating systems, such as widely used in the coating of bicycles, motorcycles, automobiles, refrigerators, washing machines, electric fans, instruments, meters, precision machinery and IT products. Pack. [0003] When applying the above-mentioned thermosetting acrylic metallic paint, it is usually necessary to first a...
