METHOD FOR THE PREPARATION OF HARD FOAM COMPOSITE ELEMENTS WITH ISOCYANATE REACTIVE BONDING AGENTS

摘要

The present invention relates to a method for producing a composite element, at least comprising the steps of providing a cover layer; applying a composition Z1, which contains at least one isocyanate-reactive compound, to the cover layer; and applying a composition Z2, which is suitable for producing a polyurethane and/or polyisocyanurate foam, to the previously applied layer, and to composite elements obtainable or obtained according to said method.
