This specialized sealant is formulated with active chromate inhibitors that provide a chemical barrier against oxidation and galvanic decay. Its low-viscosity, Type III consistency is specifically engineered for spray application, allowing technicians to apply a uniform, protective coating over large faying surfaces, stringers, and internal wing structures.
