热固性丙烯酸树脂是指在结构中带有一定的官能团，在制漆时通过和加入的氨基树脂、环氧树脂、聚氨酯等中的官能团反应形成网状结构，热固性树脂一般相对分子量较低。热固性丙烯酸涂料有优异的丰满度、光泽、硬度、耐溶剂性、耐侯性、在高温烘烤时不变色、不返黄。最重要的应用是和氨基树脂配合制成氨基-丙烯酸烤漆，目前在汽车、摩托车、自行车、卷钢等产品上应用十分广泛。

Thermosetting acrylic resin is refers to a certain functional groups in the structure, through the functional reaction and amino resin, epoxy resin, polyurethane added in the paint when the formation of network structure, the thermosetting resin generally relatively low molecular weight. Thermosetting acrylic coating has excellent fullness, gloss, hardness, solvent resistance, weather resistance, no color, no yellowing in high temperature baking. The most important application is to make amino acrylic baking paint with amino resin, which is widely used in automobile, motorcycle, bicycle, coil steel and other products.
