Aerospace Sealant AC-730 Class B are fast cure, twopart,
manganese-cured, non-chromated corrosion inhibiting
sealants. These sealants provide an effective barrier against the
common causes of corrosion on aluminum and between
dissimilar metals. 3M AC-730 Class B Sealants have outstanding
resistance to aviation gasoline and jet fuel, as well as resistance
to chemicals, hydraulic fluids and petroleum products common
to the aircraft industry. The mixed compound is a thixotropic
paste, easily applied by spatula, extrusion gun or injection gun.
They maintain flexibility and bond strength on most metal
substrates under extremes of temperature, weathering and stress.
Features:
Efficiently maintains flexibility and bond strength on various metals
Easy to apply using spatula, extrusion gun or injection dispenser
Provides low shrinkage results in less rework
Density of 1.58 grams per liter for part-A catalyst and 1.5 grams per liter for part-B base
Viscosity of 9500 to 16,000 poise at 77 degrees F for part-B base
Withstands a tensile strength of 200 psi
Flash point greater than or equal to 200 degrees F
Benefits:
Employs non-chromate corrosion inhibitive formula, thereby helping to comply with chromate reduction initiatives
Suitable for use on most metal substrates including aluminum and between other dissimilar metals
Applications:
Seals faying surfaces of mating parts
Seals joints from passage of liquid or air
Prevents corrosion and channeling leakage
Specifications:
AMS 3265
FAM-3104
LMA MU006 Type I, DPM 5896-2 and 5PTMUT06 Type I
