3M™ Aerospace AC-350 B-1/4 Gray AMS3276G Class B-1/4 Spec Fuel Tank & Fuselage Sealant - 25 Gram Kit

* Application life refers to the length of time the mixed compound remains at a consistency suitable for application with spatula or caulking gun. Application life is always measured as a standard temperature of 77°F with a relative humidity level of 50%. In general, for every 20°F rise in temperature, the application life is halved; and for every 20°F drop, it is doubled. High humidity levels during the mixing process will shorten application life.

** Tack-free time is the length of time after which a mixed sealant will no longer tightly adhere to L-LP-690 standard low density polyethylene film.

*** Cure time is defined as the length of time it takes AC-350 sealant to reach 30A hardness. It depends on three factors: remaining application life, temperature and relative humidity. To a certain extent, the temperature/humidity factors for application life also apply to curing. To accelerate the curing process, heat may be applied up to (but not more than) 140°F.

* Of cured compound after 14 days @ 77°F/50% RH
