3M™ Aerospace Sealant AC-730 B-2, gal Kit, 4 Kit/Case

We engineered 3M™ Aerospace Sealant AC-730 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. AC-730 maintains flexibility and bond strength on aluminum, and between dissimilar metals 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.

Use with:

• 3M™ Adhesion Promoter AC-132
• 3M™ Adhesion Promoter AC-160
• 3M™ Mix & Dispense Equipment - Dispensers and Accessories

Class Distinction
