PR-1198 is a sprayable, polyurethane coating designed for use as a secondary fuel barrier on composite aircraft integral fuel tanks. The product is typically applied to the exterior surfaces of the composite center wing box tank.
Should a leak occur in the tank's primary seal system, PR-1198 will aid in the containment of the leak and prevent fuel migration. PR-1198 cures at room temperature to form a resilient transparent coating with high elongation and tensile strength properties.
