Abstract
Abstract Reactive diluents are derived from the reaction of a glycidyl ester and a hydroxyl and/or carboxyl functional compound. The diluents are useful in coating compositions together with crosslinking agents and, optionally, polyols.

Claim 1
Independent Claim
161 words
A coating composition capable of liquid application to a substrate, the vehicle portion of the composition, on a weight solids basis, consisting essentially of: (a) from about 35% to about 55% of a crosslinking agent; (b) from about 15% to about 50% of a curable polyol resin; and (c) from about 15% to about 50% of a reactive diluent derived from the reaction of (i) from about 0.25 to about 4 moles of a glycidyl ester with (ii) each mole of a functional material having a molecular weight of less than about 1000, a hydroxy equivalent weight of from about 30 to about 1000 and a carboxy equivalent weight of from about 50 to about 1000, provided the total hydroxyl and carboxyl functionality of the functional material is at least 2.0, said reactive diluent characterized in having an acid number of less than about 50, a non-volatile content of greater than about 85% and a Gardner-Holdt viscosity of less than Z-10.
