AUTOMOTIVE REFINISH PRIMER SURFACER for Automotive Surface Treatment

摘要

The present invention provides a curable coating composition containing an amine group-containing polyepoxide resin, an acetoacetate-containing polyester having a weight average molecular weight of 1000 or more, and a polyacrylate-containing material. The amine group-containing polyepoxide can be modified with ketones and / or aldehydes to produce ketimine-and / or aldamine-containing polyepoxides. The above compositions are useful as coatings for corrosion resistance, adhesiveness to substrates and other organic coatings, abrasive properties and service life, especially undercoating for ambient temperature or low temperature curable automotive surface treatment.
