The present invention aims to provide a primer composition that can give good adhesion between an acrylic resin and an inorganic substrate, such as a substrate formed of metal, metal oxide, glass, ceramic, cement, or mortar and is suitably used as a primer for bonding them together. The primer composition is produced by mixing (a) a polythiol having at least two mercapto groups in one molecule, (b) a silane compound having at least one functional group and at least one alkoxysilyl group in one molecule, the at least one functional group being reactive with a mercapto group, and water.
本发明旨在提供一种底漆组合物,该组合物可在
丙烯酸树脂和无机基材(例如由
金属、 金属氧化物、
玻璃、陶瓷、
水泥或灰浆形成的基材)之间产生良好的附着力,并适合用作 将它们粘合在一起的底漆。该底漆组合物由以下物质混合而成:(a) 聚
硫醇,其一个分子中含有至少两个巯基;(b)
硅烷化合物,其一个分子中含有至少一个官能团和至少一个烷氧基
硅基,其中至少一个官能团可与巯基反应;以及
水。
