ABSTRACT:
A water-dilutable maleinized oil base coating composition is prepared by mixing from about 30 to about 95% by weight of water-dilutable maleinized oil with from about 5 to about 70% by weight of a solid particulate epoxy group- containing compound having a number average molecular weight of at least 1000 and an epoxy equivalent weight in the range of 450 to 7500, the average particle size being from about 0.5 to 35 .mu.m. The percentages by weight of the separate binder components are based on the total weight of the two components on a solvent free basis. The novel coating composition can be used to advantage for coating any substrate and particularly for coating automobile bodies. The invention also relates to a process for applying and baking said coating composition and to substrates thus obtained.
