Bicast leather is: A split leather with a polymer coating. The polymer coating is created as a separate layer and then applied with adhesives, rather than being applied by spraying several thin coats as in ordinary leather. This results in a very even finish on a leather of generally poor quality. The thickness of the polymer layer will determine whether it can be sold as leather or re-categorised as leather laminate. Generally speaking if bicast is looked after it is hard wearing. and can be very serviceable.
