3M AC-350A2 Aerospace Sealant 70005202257 Light Gray, 4.5 oz | 3M Industrial

3M AC350A2 class A brushable aerospace sealant comes in two parts which includes part-A catalyst and part-B base. The liquid part-A catalyst is dark brown in color, while the paste part-B base is 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 1.2 grams per liter. With 62.8 degrees F flash point and 545.5 degrees F boiling point, the aromatic odored part-B base has a specific gravity of 1.27 and VOC contents of 150.4 grams per liter. This sealant is supplied in a 4.5-ounce container and can be mixed in a 100 base/10 catalyst ratio by weight to form a light gray color mixture. It requires 2 hours for application and will be sufficiently cured after 10 hours. The product withstands a temperature range of -65 to 250 degrees F.Features:Fast cure rate helps to meet various process demandsEfficiently maintains flexibility and bond strength on various metal, composite and coated substratesEasy to apply using brush or rollerProvides low shrinkage results in less reworkDensity of 1.58 grams per milliliter for part-A catalyst and 1.27 grams per milliliter for part-B baseViscosity of 250 to 500 poise at 77 degrees F for part-B baseWithstands a tensile strength of 200 psiBenefits: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, titanium, steel and stainless steelApplications:Sealing integral fuel tanksRepairing integral fuel tanksSealing fuselagesSpecifications:AMS-S-8802 Type II and AMS3276
