3M AC-730B2 Aerospace Sealant 70005203891, 2 oz | 3M Industrial

3M AC-730B2 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 of sealant is black in color, while the thixotropic paste part-B base is off-white in color. This slight odored part-A catalyst has a specific gravity greater than or equal to 1.58 and VOC contents of 0.9 grams per liter. This sulfurous odored part-B base has a specific gravity of 1.5 and VOC contents of 3.8 grams per liter. The sealant is supplied in a 2-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 24 hours. The product withstands a temperature range of -65 to 250 degrees F.Features:Efficiently maintains flexibility and bond strength on various metalsEasy to apply using spatula, extrusion gun or injection dispenserProvides low shrinkage results in less reworkDensity of 1.58 grams per liter for part-A catalyst and 1.5 grams per liter for part-B baseViscosity of 9500 to 16,000 poise at 77 degrees F for part-B baseWithstands 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 and between other dissimilar metalsApplications:Seals faying surfaces of mating partsSeals joints from passage of liquid or airPrevents corrosion and channeling leakageSpecifications:AMS 3265FAM-3104LMA MU006 Type I, DPM 5896-2 and 5PTMUT06 Type I
