Beschreibung
Zusammenfassung:	The invention relates to a method for producing composite elements comprising at least one layer made of a hard foam material a) and at least one cover layer b), said method at least having the steps of providing a flowable starting material a) and applying the flowable starting material a) onto the cover layer b) by means of a stationary application device c) while the cover layer b) is continuously moved. The starting material a) comprises at least one polyisocyanate; at least one polyol; at least one propellant, a catalyst composition comprising at least one compound D1), selected from the group consisting of metal carboxylates and , ', "-tris(dimethylaminopropyl)-hexahydrotriazine, and at least one compound D2) which catalyzes the formation of polyurethane and which differs from the compound D1) and contains at least one amino group; and optionally auxiliary agents and additives. According to the invention, the polyol component (component B)) is selected from polyetheroles, and the starting material a) is free of polyesteroles. The invention further relates to composite elements which can be obtained according to such a method.
