Leather Finishing

Automotive leather used to produce car seats has to show excellent appearance and soft-feel, high durability and light fastness, good water, chemical and abrasion resistance. In order to satisfy these requirements, the leather is treated with finishing formulations, usually based on waterborne polyurethane technology. Hydrophilic aliphatic polyisocyanates, which are safer for end-users, are preferred to polyaziridine crosslinkers. Besides, polyisocyanate crosslinkers bring better durability and longer lasting performance than polyaziridine.
