The thermoplastic acrylic resin does not undergo further crosslinking during the film formation process, so its relative molecular weight is large, it has good light and color retention, water and chemical resistance, fast drying, convenient construction, easy application recoating and rework, preparation When aluminum powder paint, the whiteness and positioning of aluminum powder are good. Thermoplastic acrylic resin is widely used in automotive, electrical, machinery, construction and other fields.
Thermosetting acrylic resins have a certain functional group in the structure. They form a network structure by reacting with functional groups in amino resins, epoxy resins, polyurethanes, etc. added during the production of paint. Thermosetting resins generally have relatively low molecular weight. Thermosetting acrylic paint has excellent fullness, gloss, hardness, solvent resistance, weather resistance, does not change color and does not return yellow when baked at high temperature. The most important application is to make amino-acrylic baking paint in combination with amino resin. It is currently widely used in automobiles, motorcycles, bicycles, rolled steel and other products.
