The present invention provides a polyvinyl chloride plastisol composition characterized by containing a specified epoxy resin, a blocked isocyanate and, if necessary, a latent curing agent for an epoxy resin as tackifiers. This plastisol composition is excellent in storage stability and can strongly adhere to various metals and various undercoats of metals (such as electro-deposit) by baking even at a relatively low temperature to give a coating which is free from blowing and exhibits excellent adhesion after the immersion in hot water or the heating. Therefore, the composition is useful as a body sealer or undercoat for an automotive body.
本发明提供了一种聚氯乙烯增塑溶胶组合物,其特点是含有特定的环氧树脂、封端异氰酸酯,必要时还含有环氧树脂的潜在固化剂作为增粘剂。这种增塑溶胶组合物具有出色的储存稳定性,即使在相对较低的温度下烘烤,也能牢固地附着在各种金属和金属的各种底涂层(如电沉积层)上,使涂层在热水中浸泡或加热后不起泡,并表现出出色的附着力。因此,该组合物可用作汽车车身的密封剂或底漆。
