AL2CHEM SPECIALTIES AL 69C Silane/Carbon Black

AL 69C is a 50/50 mixture of AL69 with N330 carbon black to form a free flowing granule that is easy to use and at the same time utilize the properties of the AL 69 silane. AL 69 is a bifunctional polysulfidic organosilane for the rubber industry. It is used to improve the reinforcing capability of fillers with silanol group on their surface (e.g., silicas, silicates, clay, etc.), and also as an integral part of curing systems to improve crosslinking network properties.

Chemical Name: Bis[3- (triethoxysilyl) propyl] tetrasulfide
