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.
