3M AC-735B2 Aerospace Sealant 70005204360, 3.5 oz | 3M Industrial

3M AC735B2 class B non-sag aerospace sealant comes in two parts which includes part-A catalyst and part-B base. The liquid part-A catalyst of sealant is dark brown in color, while the paste part-B base is off-white in color. This slight odored part-A catalyst has a specific gravity of 1.58 and VOC contents of 0.7 grams per liter. This sulfurous odored part-B base has a specific gravity of 1.1 and VOC contents of 1.9 grams per liter. The sealant is supplied in a 3.5-ounce container and can be mixed in a 100 base/10 catalyst ratio by weight to form a mixed compound. It requires 2 hours for application and will be sufficiently cured after 10 hours. The product withstands a service temperature range of -65 to 250 degrees F.Features:Efficiently maintains flexibility and bond strength on various metal and coated substratesEasy to apply using spatula, extrusion gun or injection dispenserUses low-density formula that weighs 3 to 4 pounds less per gallon than traditional sealantsQuick cure rate helps to achieve increased throughputProvides low shrinkage results in less reworkDensity of 1.58 grams per milliliter for part-A catalyst and 1.1 grams per milliliter for part-B baseViscosity of 11,000 to 13,000 poise at 77 degrees F for part-A catalystWithstands a tensile strength of 200 psiFlash point greater than or equal to 200 degrees FBenefits:Employs non-chromate corrosion inhibitive formula, thereby helping to comply with chromate reduction initiativesSuitable for use on most metal substrates including aluminum, titanium, steel and stainless steelApplications:Corrosion protectionSealing fuselagesFilling voidsSpecifications:MIL-PRF-81733, Class I, Grade B, Type II
