Overview
3M™ AC770B1 class B non-sag 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 thixotropic paste part-B base is off-white in color. This slight odored part-A catalyst has a specific gravity of 1.58 and VOC contents of 0.9 grams per liter. This sulfurous odored part-B base has a specific gravity of 1.1 and VOC contents of 3.4 grams per liter. The sealant is supplied in a 25-gram container and can be mixed in a 100 base/10 catalyst ratio by weight to form a mixed compound. It requires 1 hour for application and will be sufficiently cured after 5 to 6 hour. The product withstands a temperature range of -65 to 250 degrees F.
