    • The present invention is directed to two component coating compositions that cure under ambient conditions and more particularly to those having low VOC (volatile organic content) that are suitable for use in automotive refinish and Original Equipment Manufacturing (OEM) applications. The coating composition includes crosslinkable and crosslinking components, wherein the crosslinkable component includes a low polydispersity, low molecular weight copolymer having on an average 2 to 25 crosslinkable functional groups, such as hydroxyl, acetoacetoxy, carboxyl, epoxy, primary amine and secondary amine. The copolymer is polymerized from a monomer mixture that includes one or more non-functional methacrylate monomers and one or more functional acrylate monomers provided with the functional groups. The crosslinking component includes polyisocyanate, polyamine, epoxy, polyacid, ketimine, melamine, or a combination thereof. The invention is also directed to coating produced from the coating composition.
    • 本发明涉及在环境条件下固化的二组分涂料组合物,更具体地涉及适用于汽车修补漆和原始设备制造(OEM)应用的具有低VOC(挥发性有机物含量)的组分涂料组合物。 涂料组合物包括可交联和交联组分,其中可交联组分包括具有平均2至25个可交联官能团的低分子量低分子量共聚物,例如羟基,乙酰乙酰氧基,羧基,环氧基,伯胺和仲胺。 共聚物由包含一种或多种非官能的甲基丙烯酸酯单体和一个或多个提供有官能团的官能丙烯酸酯单体的单体混合物聚合。 交联组分包括多异氰酸酯,多胺,环氧,多酸,酮亚胺,三聚氰胺或其组合。 本发明还涉及由涂料组合物制备的涂料。
