Abstract
A two-component urethane adhesive is disclosed which requires no primer or pretreatment of the substrate. The adhesive in cured form has superior paint adhesion and can withstand high temperature bake cycles without substantial losses in adhesion to the substrate. The adhesive differs from prior adhesives in that essentially all of the high molecular weight polyols in the prepolymer component are the reaction product grafting reactions of acrylonitrile onto polypropylene polyols.
