The present invention relates to an adhesion promoting composition comprising at least one binder having an isocyanate group. This particular binder is prepared from a mixture of polyester resin A, at least one diphenylmethane diisocyanate monomer, and at least one polyisocyanate B, wherein the monomeric MDI portion is 2% by weight or less of the total composition. It is. Such binder compositions are particularly suitable for new generation automotive paints in particular and are highly desirable both environmentally and toxicologically due to their low content of diphenylmethane diisocyanate monomer (MDI). |
