The black Nitrile Butadiene Rubber (NBR) coating can be applied on one or both sides of the metal, either on coldrolled steel or on stainless steel depending on the final characteristics. It is suitable for use in various applications such as gaskets, cylinder head gaskets, casings, valves, brake pad parts… as well as in applications requiring good overall insulation, exhibiting excellent performance at temperature and strong substrate adherence.
