TMTM-75

Characteristics and Applications

An ultra-accelerator for natural and synthetic rubbers with excellent dispersibility during compound mixing. It has a longer delayed-action effect than thiuram disulfide and dithiocarbamate accelerators and features superior scorch resistance. It can be used alone or blended with thiazole, aldamine and guanidine accelerators, and acts as an activator for thiazole accelerators. When applied to butyl rubber, it is preferably used together with thiazole, aldamine and guanidine accelerators, and premature vulcanization generally will not occur. It serves as a mild accelerator for Type 54-1 (W-type) neoprene and exhibits a retarding vulcanization effect in general-purpose (GN-A type) neoprene. It cannot be used as a vulcanizing agent. It is suitable for sealing strips, light-colored and colored molded and extruded rubber products.
