ABSTRACT:
The present invention is drawn to a polyurethane-polyester hybrid resin system wherein the components of the system have improved shelf life stability. The resin system comprises an A-Side comprising a multifunctional isocyanate and a free radical initiator. The hybrid resin system also comprises a B-Side comprising a hydroxyl-terminated unsaturated polyester polyol, an ethylenically unsaturated monomer, a polyurethane catalyst, a polymerization inhibitor, and optionally a peroxide promoter, chain extender and filler. The B-Side polymerization inhibitor of the present invention comprises substituted hindered phenol-type compounds with ring substituents producing activated benzylic hydrogens, nitrophenols with or without benzylic-type substituents, naphthoquinones, stabilized radical compounds, and mixtures thereof.
