High solids thermosetting coating compositions, cured coatings, coated articles, and processes

摘要

Disclosed herein are high solids thermosetting compositions comprising a solution of a soft, low molecular weight, hydroxy-functional addition polymer resin and a low molecular weight reactive diluent having two or three aliphatic hydroxyl groups per molecule, the weight ratio of resin to diluent being greater than 1, said coating composition when combined with melamine crosslinking agent being of sprayable, roller coatable, or dip coatable viscosity. Cured coatings, coated articles and processes of coating an article are also disclosed.
