Properties:

Without odour and poison. Stimulative to the skin and the respiratory tract. Soluble in chlorlfom acetone, methylene chloride, benzene; not easily soluble in carbon tetrachloride, ethyl acetate; insoluble in water and gasoline.

Application:

TMTD can be used as a single accelerator, as a secondary accelerator or as a sulfur donor in most sulfur-cured elastomers. TMTD is scorchy and gives fast cure rates. In sulfurless and EV cure systems TMTD produces an excellent vulcanization plateau with good heat aging and compression set resistance. Good color retention is obtained 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.

Package:

25kg N.W./bag, in plastic fabric laminated kraft bags lined with plastic bags.

Storage:

stable indefinitely under normal storage conditions.
