Provided is a thermally curable coating composition for alloy substrates, comprising: curable components, comprising an epoxy resin and a multifunctional (meth)acrylate; latent curing agents, which crosslink with the curable components upon heating, and comprise an isocyanate having at least two NCO groups and an amino resin; a curing promoter, comprising an aromatic phosphate comprising at least one hydroxy group connected with the phosphorous atom; and an organic solvent. Also provided are a method for providing a coating layer onto an alloy substrate and a coating layer thus obtained.
本发明提供了一种用于合金基材的热固化涂层组合物,其中包括:可固化成分,包括环氧树脂和多功能(甲基)丙烯酸酯;潜伏固化剂,在加热时与可固化成分交联,包括具有至少两个 NCO 基团的异氰酸酯和氨基树脂;固化促进剂,包括芳香族磷酸酯,其含有至少一个与磷原子相连的羟基;以及有机溶剂。此外,还提供了一种在合金基体上提供涂层的方法以及由此获得的涂层。
