氯化亚锡对UPR固化的促进作用

STANNOUS CHLORIDE AS ACCELERATOR FOR HARDENING OF UPR

在ＵＰＲ室温固化过程中，用过氧化二苯甲酰为引发剂，氯化亚锡为促进剂，邻磺酰苯甲酰亚胺为助促进剂，可代替有毒的叔胺类促进剂，浇铸体的色泽也得到了改善。

In this paper, stannous chloride and o-sulfonic benzoic imid were used with good results instead of toxic tertiary amine in peroxide crosslinking of unsaturated polyster resin, improving the work environment and the colour of castings.
