Abstract
Storage-stable acrylate-functional alkyd resin compositions are disclosed that include an acrylate-functional alkyd resin and a monofunctional mercaptan such as a chain transfer agent. The compositions disclosed exhibit excellent stability on storage, and have utility as binders for coating compositions useful as low VOC, quick dry paints.
Claims53
An alkyd resin composition, comprising:
- (I) an acrylate-functional alkyd resin;
- and
- (II) from about 100 ppm to about 2000 ppm, based on the acrylate-functional alkyd resin, of a monofunctional mercaptan.
An ambient oxidative-cure composition, comprising:
- (a) an alkyd resin composition that includes
- (I) an acrylate-functional alkyd resin, and
- (II) from about 100 ppm to about 2000 ppm, based on the acrylate-functional alkyd resin, of a monofunctional mercaptan;
- (b) at least one drier;
- and
- (c) a solvent selected from the group consisting of an organic solvent, water, and mixtures thereof.
A method of improving the storage stability of an acrylate-functional alkyd resin composition, comprising adding to the resin composition from about 100 ppm to about 2000 ppm, based on the acrylate-functional alkyd resin, of a monofunctional mercaptan.
A method of preparing an ambient oxidative-cure composition, comprising combining:
- (a) an alkyd resin composition that includes
- (I) an acrylate-functional alkyd resin, and
- (II) from about 100 ppm to about 2000 ppm, based on the acrylate-functional alkyd resin, of a monofunctional mercaptan;
- (b) at least one drier;
- and
- (c) a solvent selected from the group consisting of an organic solvent, water, and mixtures thereof.
A method of preparing a storage-stable acrylate-functional alkyd resin composition, comprising the steps of:
- reacting (i) a carboxyl-functional alkyd resin, and (ii) a glycidyl acrylate, wherein the glycidyl moiety of the glycidyl acrylate is the reactive moiety and the reaction product contains terminal reactive acrylate moieties, to obtain an acrylate-functional alkyd resin;
- and
- adding to the acrylate-functional alkyd resin:
- a) at least one drier,
- b) a solvent selected from the group consisting of an organic solvent, water, and mixtures thereof, and
- c) from about 100 ppm to about 2000 ppm, based on the acrylate-functional alkyd resin, of a monofunctional mercaptan, to obtain the storage-stable acrylate-functional alkyd resin composition.
