This article describes an innovative method of coupling polyurethane elastomer (based on polyurethane glycolysate) with constructional steel, by implementation of a Glaspur®—glass lacquer containing latent polyurethanes and monosilane adhesion promoters. The commonly applied coupling agent is Cilbond® 45SF glue or its derivatives. Additionally, glycolysate was synthesised from polyurethane waste and 1,3-propylene glycol in 6:1 proportion. Results of examination confirm the usefulness of the above-mentioned glass lacquer for preparing laminar polyurethane–steel elements. Strength tests unequivocally present higher tear resistance of elements prepared with lacquer than couplings with Cilbond.
