Abstract

The invention relates to a special finishing paint for thermosetting acrylic hubs. The finishing paint comprises the following components: 30-38wt% of thermosetting acrylic resin, 20-27wt% of amino resin, 3.5-5.0wt% of aids and 30-40wt% of solvent. The finishing paint has the beneficial effects that the finishing paint has excellent adhesiveness and solvent resistance and is suitable for the automobile hubs, bicycles, motorcycles, cars and the like; and the films formed by coating the paint are flat and thick and have high construction solids, good levelling property, high fullness, high lusters, high hardness and excellent weather resistance.

Description

technical field [0001] The invention belongs to the technical field of coatings, more specifically, the invention relates to a thermosetting acrylic wheel hub special finish 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] Steel wheels, aluminum wheels, etc. are used as motor vehicle wheels for fixing pipes, ...
