This invention provides a polyaddition product formed from amine compound having polyoxyalkylene chain(s) and monoepoxysilane, which has a weight-average molecular weight within a range of 250-10,000, as an additive of favorable paint stability. The polyaddition product gives, when used in cationic electropaints, coating film which is excellent in coating operability such as finished appearance, oil-cissing resistance, water mark insensibility; sealer adherability; and corrosion resistance.
本发明提供了一种聚加成产物,该产物由具有多个氧化烷基链的胺化合物和单环氧基
硅烷形成,其重均分子量在250-10,000范围内,作为有利的涂料稳定剂。当在阳离子电泳涂料中使用时,聚加成产物能够产生涂层膜,该膜在涂装操作性方面表现出色,如表面光洁度、耐油性、抗
水印敏感性;密封剂附着性;以及耐腐蚀性。
