3M AC-665 B-2 Aerospace Sealant 70005203503, 3.5 oz cartridge | 3M Industrial

3M AC-665 B-2 class B non-sag aerospace sealant is ideal for offering effective barrier against the common causes of corrosion. This product comes in two parts which includes part-A catalyst and part-B base. The liquid part-A catalyst is black in color, while the thixotropic paste part-B base is yellow in color. This slight odored part-A catalyst has a specific gravity of 1.97 and VOC contents of 0 grams per liter. This sulfurous odored part-B base has a specific gravity of 1.53 and VOC contents of 6.2 grams per liter. The sealant is supplied in a 3.5-ounce cartridge 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 40 hours. The product withstands a service temperature range of -65 to 250 degrees F.Features:Standard cure rate helps to meet various process demandsEfficiently maintains flexibility and bond strength on various metalsEmploys corrosion inhibiting formula and meets multiple aerospace material specificationsEasy to apply using spatula, extrusion gun or injection dispenserDensity of 1.97 grams per milliliter for part-A catalyst and 1.53 grams per milliliter for part-B baseViscosity of 6000 to 14,000 poise at 77 degrees F for part-B baseFlash point greater than or equal to 200 degrees FBenefits:Sealant offers an excellent resistance to aviation gasoline/jet fuel and chemical/petroleum products commonly used in aircraft industrySuitable for use on most metal substrates including aluminum and between other dissimilar metalsApplications:Seals faying surfaces of mating partsSeals joints from passage of liquid or airPrevents corrosion and channeling leakageSpecifications:MIL-PRF-81733, Class I, Grade A, Type IIBAMS 552-007 and CMNP007 Type X
