The invention relates to a method for producing a foam composite element, comprising the steps of providing a cover layer, applying an adhesion promoter layer to the cover layer, wherein the adhesion promoter layer includes a urethane-modified isocyanate, and applying a foam layer of polyurethane and/or polyisocyanurate to the adhesion promoter layer. The urethane-modified isocyanate in the adhesion promoter layer contains free isocyanate groups from > 10% to 25% when applied. The invention further relates to the application of a urethane-modified isocyanate containing free isocyanate groups from > 10% to 25% as an adhesive promoter in the production of foam composite elements, and the foam composite elements produced according to the method of the invention. |
