AL2CHEM SPECIALTIES AL 69 Silane

CAS Number: 40372-72-3
EC Number: 254-896-5
Chemical Name: Bis[3- (triethoxysilyl) propyl] tetrasulfide
Chemical Family: Sulfide Compounds

AL69 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.
