PRC Desoto - PR-1197 Secondary Fuel Barrier Coating - Pint
PR-1197 is a sprayable, polyurethane coating designed for use as a secondary fuel barrier on aircraft integral fuel tanks. The product is typically applied to the exterior surfaces of the center wing box tank. Should a leak occur in the tank's primary seal system, PR-1197 will aid in containment of the leak and prevent fuel migration.
The uncured material when mixed is very thixotropic which allows it to obtain a good film thickness even on vertical surfaces. It cures at room temperature to form a resilient transparent coating with high elongation and tensile strength properties.
