Setalux 7202 aceto-acetate functional acrylic resin 带乙酰乙酸功能丙烯酸树脂
Setalux 7002 ketimine functional a酮亚胺功能树脂
cPrinciple原理:
The ketimine groups in the crosslinker are deblocked by traces of water (humidity). The resulting primary amines react very fast with the aceto-acetate groups to form enamine bonds. 酮亚胺官能团由水(湿度
