Rhenogran® DOTG-70

Rhenogran® DOTG-70 by Rhein Chemie Additives (Lanxess Group) is an accelerator for the vulcanization of natural- and synthetic rubber. It causes very slow onset of cure and a relatively slow rate of cure. It is recommended to be used with anti-oxidant, as it causes strong reversion if used alone. In combination with mercapto, sulfenamide, thiuram and di-thiocarbamate accelerators, reciprocal activation and secondary acceleration can be achieved. It enhances cross-linking density, rate of cure and can obtained good mechanical properties and ageing resistance. It contains ethylene propylene diene rubber (EPDM) as a binder. It is designed for technical articles (especially thick-walled components), band tires, damping elements, roller coverings and cable sheathing. Rhenogran® DOTG-70 has a shelf life of 2 years.
