ABSTRACT:
A fatigue crack growth retardant material for application to aluminum and alloys thereof utilizes certain organic nitrogen compounds and an elastomeric polymer compatible herewith with respect to the curing properties thereof as well as the ultimate properties of the material and capable of stabilizing the nitrogen compound so as to inhibit the evaporation thereof to the atmosphere. The material inhibits corrosion of and retards crack growth in aluminum and alloys thereof when applied thereto. The material has particular utility when applied to the surfaces of structural parts of aircraft and is utilized as a protective coating as well as a sealant, dependent upon the amount of solvent added to the polymeric elastomer.
