What are the characteristics of acrylic resin?

Acrylic resin is a resin made by copolymerization of acrylic esters and methacrylic esters and other ethylenic monomers. By choosing different resin structures, different formulations, production processes and solvents, different types and different properties can be synthesized Unlike acrylic resins in different applications, acrylic resins can be divided into thermoplastic acrylic resins and thermosetting acrylic resins according to differences in structure and film-forming mechanism.
The main absorption peak of light of acrylic resin copolymerized with acrylate and methacrylate monomers is outside the range of the solar spectrum, so the acrylic resin paint obtained has excellent light resistance and outdoor aging resistance.
Features

The thermoplastic acrylic resin does not undergo further cross-linking during the film formation process, so it has a relatively large molecular weight, good gloss and color retention, water and chemical resistance, fast drying, easy construction, easy construction recoating and rework, preparation Aluminum powder has good whiteness and localization when it is painted. Thermoplastic acrylic resin is widely used in automotive, electrical appliances, machinery, construction and other fields.
Thermosetting acrylic resin means that it has certain functional groups in the structure, and it forms a network structure by reacting with the functional groups in the added amino resin, epoxy resin, polyurethane, etc. during the production of paint. Thermosetting resins generally have a relatively low molecular weight. Thermosetting acrylic coatings have excellent fullness, gloss, hardness, solvent resistance, weather resistance, do not change color and do not return to yellow when baked at high temperature. The most important application is to make amino-acrylic paint with amino resin. It is widely used in automobiles, motorcycles, bicycles, steel coils and other products.
