Abstract
The invention relates to alcohol-modified glycidyl carbamate resins wherein at least some of the glycidol groups in the resin have been replaced with an alcohol. The invention also relates to coating compositions containing the resins.
Claims18
A solvent-based coating composition comprising an alcohol-modified glycidyl carbamate compound of formula (I), (II), (III), or (IV):
- wherein:
- R2 is independently an optionally substituted, divalent C1-C15 alkyl, an optionally substituted divalent C3-C15 cycloalkyl, or a divalent substituent selected from the group consisting of
- X represents either the glycidyl group:
- or an alkyl group based on an alcohol, represented as:
- wherein at least two of the X moieties are represented by the glycidyl group;
- n ranges from 1-50;
- m ranges from 1-15;
- and
- R3 is independently an optionally substituted C1-C22 alkyl.
A glycidyl carbamate functional resin that is the reaction product of an isocyanate having at least three isocyanate groups per molecule, glycidol, and an alcohol, wherein the equivalent ratio of glycidol to alcohol in the resin ranges from 1:2 to 49:1.
