ABSTRACT:
A polyester resin is made by esterifying a reaction mixture comprising specific amounts of a diol, a triol, an a cyclic dicarboxylic acid, an unsaturated, aliphatic dicarboxylic acid such as maleic acid and a saturated, aliphatic dicarboxylic acid.
The polyester resin is cross-linked with an aminoplast resin to produce a one-coat chemical coating which dispenses with the need to use a primer coat.
Another embodiment of this invention includes the use of a highly aromatic, polyhydroxy, low molecular weight polymer in the polyester resin formulation.
