Abstract
A low volatile organic compound (VOC) coating composition with a low viscosity is described. The coating composition includes a hydrocarbon solvent; a reactive or non-reactive diluent; a drier composition; and a hyper-branched alkylated polymer. A colorant can be added so that the coating composition can be used as a stain, such as a wood stain. The hyper-branched alkylated polymer functions as the main binder to provide an effective coating composition having a relatively low VOC level.
Claims28
A coating composition, comprising:
- at least one hyper-branched alkylated polymer, wherein the hyper-branched alkylated polymer is derived from a fatty acid or a blend of fatty acids with a conjugated content of greater than about 11%;
- a drier accelerator;
- and
- an anti-skinning agent;
- wherein the coating composition has a viscosity of less than about 1500 cps and a volatile organic compound (VOC) content of less than about 250 g/L.
A method for coating a surface, comprising applying a low volatile organic compound coating composition having a viscosity of less than about 1500 cps and a volatile organic compound (VOC) content of less than 250 g/L to the surface and removing any excess of the coating composition from the surface, wherein the coating composition comprises an anti-skinning agent;
- a drier accelerator;
- and a hyper-branched alkylated polymer, wherein the hyper-branched alkylated polymer is derived from a fatty acid or a blend of fatty acids with a conjugated content of greater than about 11%.
