Wellt TMTM
Generally used as a secondary accelerator or as a booster for sulfenamides to achieve faster cure rates. Wellt TMTM is distinguished by very good processing safety in comparison with other thiurams. High curing activity and no discoloration. Unlike the thiuram disulfides. Wellt TMTM will not produce cures in the absence of added elemental sulfur. It is an excellent accelerator for polychloroprene in association with Wellt DPG and sulpur.
