The concept and characteristics of acrylic resin
Oct 16, 2018

Acrylic resin is a generic term for polymers of acrylic acid, methacrylic acid and derivatives thereof. The acrylic resin coating is a thermoplastic or thermosetting resin coating made of an acrylic resin obtained by copolymerizing (meth) acrylate or styrene with other acrylates, or an acrylic radiation coating.

The thermoplastic acrylic resin does not undergo further crosslinking during the film formation process, so its relative molecular weight is large, with good gloss and color retention, water and chemical resistance, fast drying, convenient construction, easy construction recoating and rework, preparation The whiteness and positioning of the aluminum powder are good when the aluminum powder is painted. Thermoplastic acrylic resins are widely used in the fields of automobiles, electrical appliances, machinery, and construction.

The thermosetting acrylic resin means a certain functional group in the structure, and forms a network structure by reacting with a functional group in an amino resin, an epoxy resin, a polyurethane or the like added during the painting, and the thermosetting resin generally has a relatively low molecular weight. Thermosetting acrylic coatings have excellent fullness, gloss, hardness, solvent resistance, weather resistance, no discoloration when baked at high temperatures, and no yellowing. The most important application is the combination of amino resin and amino-acrylic baking varnish. It is widely used in automobiles, motorcycles, bicycles, coiled steel and other products.
