ACCELERATOR TMT

TMT Ultra Thiuram AcceleratorAccicure. It is the best known and the most widely used very fast accelerators. It is

used with sulphur as a single accelerator and as an important component of multi accelerator blends. It is non

staining but with normal sulphur dosages it is rather too scorchy to be used by itself. It also cures rubber without

added sulphur, acting as both accelerator and sulphur donor. TMT is a very popular booster for MBT, MBTS and

HBS, giving reasonably safe, fast-curing combinations. Typical dosage varies from 0.15 – 0.75 phr.

Storage and Handling

Stable indefinitely under normal storage conditions. No special handling precautions are necessary. Normal

precautions to avoid contact with skin and eyes should be followed. For eyes, flush with plenty of water and

seek medical advice.
