ABSTRACT:
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 undercoate 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.
