3M AC-730C8 Aerospace Sealant 70005204162 Dark Gray, 2 oz | 3M Industrial

3M AC730C8 class C fay surface 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 beige (white) in color. With greater than or equal to 200 degrees F flash point, the slight odored part-A catalyst has a specific gravity of 1.58 and VOC contents of 1.5 grams per liter. With 150 degrees F flash point, the aromatic odored part-B base has a specific gravity of 1.42 and VOC contents of 88.5 grams per liter. This sealant is supplied in a 2-ounce container and can be mixed in a 100 base/10 catalyst ratio by weight to form a dark gray color mixture. It requires 8 hours for application and will be sufficiently cured after 7 days. 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 brush, roller, spatula or extrusion gunProvides low shrinkage results in less reworkDensity of 1.58 grams per liter for part-A catalyst and 1.42 grams per liter for part-B baseViscosity of 6000 to 14,000 poise at 77 degrees F for part-B baseWithstands shear strength of 350 psiBenefits: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 3265
