We engineered 3M™ Aerospace Sealant AC-735 specifically for fuselage applications, where it offers a number of advantages and benefits compared to traditional sealants. For starters, it is corrosion inhibitive yet contains no added chromate, which may help you comply with chromate reduction initiatives and OSHA requirements. Its lighter weight formula, 25% lower density than traditional sealants, saves vital aircraft weight. AC-735 maintains flexibility and bond strength on aluminum, titanium, steel, stainless steel, composites and many coatings under extremes of temperature, weathering and stress. Designed for easy tooling, it has outstanding resistance to jet fuel, chemicals and petroleum products common throughout the aerospace industry.
