3M™ AC-730C8 Aerospace Sealant 70005204204 Dark Gray, 3.5 oz

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 3.5-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.
