Abstract
A waterborne acetoacetate-functionalized alkyd coating composition is disclosed which includes an acetoacetate-functionalized alkyd resin, at least one drier, and water. The acetoacetate-functionalized alkyd resin is the reaction product of (i) an alkyd resin, and (ii) an alkyl acetoacetate. Also disclosed is a method of preparing a waterborne acetoacetate-functionalized alkyd coating composition which includes the step of contacting an acetoacetate-functionalized alkyd resin with at least one drier in the presence of water.
Claims22
An acetoacetate-functionalized alkyd resin, comprising the reaction product of:
- (a) from about 70 to about 97 wt % of an alkyd resin having an acid number of from 0 to about 100 mg KOH/g;
- and
- (b) about 3 to about 30 wt % of an alkyl acetoacetate, wherein the weight percents are based on the total weight of (a) and (b).
A method of making a waterborne acetoacetate-functionalized alkyd coating composition, comprising the steps of combining:
- (I) an acetoacetate-functionalized alkyd resin, comprising the reaction product of:
- (a) a hydroxyl-functional alkyd resin having an acid number of from 0 to about 100 mg KOH/g, and
- (b) an alkyl acetoacetate;
- (II) at least one drier;
- and
- (III) water.
A method of making an acetoacetate-functionalized alkyd resin, comprising reacting:
- (a) an alkyd resin, present in an amount of from about 70 to about 97 wt %;
- and
- (b) an alkyl acetoacetate, present in amount of from about 3 to about 30 wt %,
- wherein the amounts are based on the total weight of (a) and (b).
A method of making an acetoacetate-functionalized alkyd resin, comprising reacting, at 100-140°:
- (a) an alkyd resin, present in an amount of from about 85 to about 95 wt %;
- and
- (b) t-butyl acetoacetate, present in an amount of from about 5 to about 15 wt %,
- wherein the weight percents are based on the total weight of (a) and (b).
