Aliphatic Polyurethanes are excellent topcoat materials defending the leather surface with excellent UV resistance and mechanical resistance, offering stable colors for many years. High compatibility with PVC substrates makes aliphatic polyurethanes even more desirable for vinyl leather applications. When high end performance is required, aliphatic polycarbonate polyurethanes meet the technical expectations of challenging applications such as, automotive and marine industry, combining chemical and mechanical resistance with UV fastness and excellent weatherability.
