TMTD can be used as a single accelerator, as a secondary
accelerator or as a sulfur donor in most sulfur-cured elastomers. TMTD
is scorch and gives fast cure rates. In sulfur less and EV cure system
TMTD produces an excellent vulcanization plateau with good heat aging
and compression set resistance. Good color retention is obtaining in
non-black vulcanizates. TMTD is a valuable secondary accelerator for
EPDM. In the vulcanization of polychloroprene rubber with N,N'-ethylene
thiourea, TMTD may be used as a retarder.
