ABSTRACT:
Blends of low molecular weight hydroxy-terminated polyesters, based on diols, such as 2,2,4-trimethyl-1,3-pentane diol, and diacids or their esters, such as isophthalic acid, and methyl esters of short chain aliphatic diacids, are provided. The blends can be crosslinked with conventional crosslinking agents such as nitrogen resins or polyisocyanates. The formulated coatings have high solids content of relatively low viscosities and are useful on e.g. metallic substrates forming, upon curing, coatings having excellent tensile strength, hardness, and resistance to staining, weathering, and corrosive conditions.
