Abstract
A coating composition comprising an acetoacyl-functional polymer, an organic solvent, and a crosslinking agent.
Claims20
A coating composition comprising:
- a polymer comprising an organic backbone and at least one acetoacyl-functional group;
- at least one carbonyl-functional solvent compound having a sufficient concentration in the coating composition to provide a pot life that is greater than a pot life attainable with an equal concentration of xylene, wherein a concentration of solvent-based carbonyl groups from the at least one carbonyl-functional solvent compound constitutes greater than about 15% by weight of the coating composition, based on an entire weight of the coating composition;
- and
- a crosslinking agent.

A method of coating a substrate, the method comprising:
- providing a coating composition comprising a polymer having an organic backbone and at least one acetoacyl-functional group, at least one crosslinking agent, and at least one carbonyl-functional solvent compound, wherein a concentration of solvent-based carbonyl groups from the at least one carbonyl-functional solvent compound constitutes greater than about 15% by weight of the coating composition, based on an entire weight of the coating composition;
- applying the coating composition to a substrate;
- removing at least a portion of the at least one carbonyl-functional solvent compound;
- and
- at least partially crosslinking the polymer with the use of the at least one crosslinking agent.

A method for forming a coating on a wood substrate, the method comprising:
- providing a solvent-borne coating composition comprising at least one crosslinking agent, an organic solvent, and a polymer having an organic backbone and a plurality of acetoacyl-functional groups, wherein the organic solvent comprises at least one carbonyl-functional solvent compound, wherein a concentration of solvent-based carbonyl groups from the at least one carbonyl-functional solvent compound constitutes greater than about 15% by weight of the solvent-borne coating composition, based on an entire weight of the solvent-borne coating composition;
- applying the solvent-borne coating composition to the wood substrate;
- removing at least a portion of the organic solvent;
- and
- at least partially crosslinking the polymer with the use of the at least one crosslinking agent.
