Abstract
Adhesion promoter compositions which include at least one binder having isocyanate groups. This specific binder is prepared from a mixture of a polyester resin A, at least one monomeric diphenylmethane diisocyanate, and at least one polyisocyanate B, where the proportion of monomeric diphenylmethane diisocyanate (MDI) is ≦2% by weight of the overall composition. Such adhesion promoter compositions are particularly suitable for new generation automotive paint systems and are very desirable from an ecological and toxicological point of view owing to their low content of MDI.
