PR-1196® - Secondary Fuel Barrier Coating
PR-1196 sprayable polyurethane coating is used as a secondary fuel barrier on integral fuel tanks. Applied to the exterior of the center wing box tank, it helps contain leaks if the primary seal fails. The thixotropic uncured material allows good film thickness on vertical surfaces. It cures at room temp. to form a resilient transparent coating with high elongation and tensile strength.

PR-1196 secondary fuel barrier coating is a sprayable, polyurethane coating designed for use 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-1196 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.
