ABSTRACT:
An ester/urethane acrylate hybrid oligomer which is the reaction product of an acrylate/hydroxy-functional polyester, an isocyanate compound, and a hydroxy-functional acrylate compound. The acrylate/hydroxy-functional polyester is prepared by reacting a polyester polyol and an acrylate compound. The polyester backbone of the oligomer has both ester and urethane linkages to the terminal acrylate functionality. This hybrid nature of the polyester backbone provides an oligomer which can be utilized at low viscosity to facilitate processing while maintaining effective stain resistance and flexibility.
