Product Description
This product is designed for the rubber industry. Two grades are available: pdr; pdr-d. All grades are white to off white.

Dimacit TMTD offers fast vulcanization and gives an excellent vulcanization plateau with good heat aging and compression set resistance when used in sulfurless vulcanization systems and EV systems.

In EPDM Dimacit TMTD is a valuable secondary accelerator.

In mercaptan modified polychloroprene cured with ETU, Dimacit TMTD acts as a scorch retarder without affecting the cure speed.

Dimacit TMTD-pdr is recommended for use in soft compounds due to dispersability.

Dimacit TMTD is non-staining and non-discoloring. Excellent colors are obtained in non-black vulcanizates.

It should be noted that in the application of Dimacit TMTD N-nitrosodimethylamine can be formed by the reaction of dimethylamine, a decomposition product, with nitrosating agents (nitrogen oxides).

TMTD is regulated for use in articles with food as specified under FDA CFR 177.2600, 175.105 and under BfR recommendation XXI.
