Abstract
An ultra-high solids coating composition is disclosed. The composition comprises a polyol blend of a liquid acrylic polyol and a resinous polyol. The polyol blend is crosslinked with a multifunctional isocyanate, melamine, or silane to form a variety of coatings. The coating composition has a significantly higher solid % than that is formulated from a single resin that has similar composition of the combination of the polyol blend. The coatings include less than about 35% by weight of an organic solvent.
