Abstract
Disclosed herein is an additive for a paint or stain composition or for a colorant composition. The additive is polymerized from at least one acrylate monomer and a chain transfer agent. The additive has a weight molecular weight from about 2,000 Daltons to about 5,000 Daltons, and the chain transfer agent comprises a hydrogen-sulfur functionality. The additive's glass transition temperature ranges from about −50° C. to about −10° C. and the additive is hydrophobic.
