Claims18
A coating composition comprising:
- an alkyd resin;
- an oxime-free anti-skinning agent that is a urea compound described by formula (I):
- wherein:
- X is independently selected from oxygen and sulfur;
- and
- R1-R4 are each independently substituted or unsubstituted C1-C24 alkyl;
- and
- a metal carboxylate drier;
- wherein the coating composition has a volatile organic content (VOC) of 40 weight percent (wt %) or less.

A method of preparing a coating composition, the method comprising:
- combining:
- an alkyd resin;
- an oxime-free anti-skinning composition that is a urea compound described by the formula (I):
- wherein:
- X is independently selected from oxygen and sulfur;
- and
- R1-R4 are each independently C1-C24 alkyl;
- and
- a metal carboxylate drier;
- in a manner sufficient to produce a coating composition that has a volatile organic content (VOC) of 40 wt % or less.
