Abstract
An ambient oxidative cure composition based on an acrylate functionalized alkyd resin is described. A method of preparing an ambient oxidative cure composition based on an acrylate functionalized alkyd resin is also described. Such ambient oxidative cure compositions may be used in, for example, fast drying, high solid paint or enamel compositions or formulations.
Claims20
An ambient oxidative cure composition comprising:
- (a) an acrylate functionalized alkyd resin comprising the reaction product of:
- (i) a hydroxyl functional alkyd resin;
- (ii) an acid anhydride;
- and
- (iii) a glycidyl acrylate
- wherein the glycidyl moiety of said glycidyl acrylate is the reactive moiety and said reaction product contains terminal reactive acrylate moieties;
- (b) at least one drier;
- and
- (c) an organic solvent.
An ambient oxidative cure enamel composition comprising:
- (a) an acrylate functionalized alkyd resin comprising the reaction product of:
- (i) a hydroxyl functional alkyd resin;
- (ii) an acid anhydride;
- and
- (iii) a glycidyl acrylate
- wherein the glycidyl moiety of said glycidyl acrylate is the reactive moiety and said reaction product contains terminal reactive acrylate moieties;
- (b) at least one drier;
- (c) an organic solvent;
- and
- (d) at least one pigment.
A method of preparing an ambient oxidative cure composition comprising the step of:
- contacting an acrylate functionalized alkyd resin with at least one drier in the presence of an organic solvent.
A method of preparing an ambient oxidative cure composition comprising the steps of:
- reacting a hydroxyl functional alkyd resin with an acid anhydride to form a carboxyl functional alkyd resin;
- reacting said carboxyl functional alkyd resin with the glycidyl moiety of a glycidyl acrylate to form an acrylate functionalized alkyd resin;
- and
- contacting said acrylate functionalized alkyd resin with at least one drier in the presence of an organic solvent.
