Perkacit TDEC is a very fast primary or secondary (ultra) accelerator for natural and synthetic rubbers.
- Perkacit TDEC offers very fast vulcanization.
- Perkacit TDEC is used as a secondary ultra accelerator for thiazole and sulfenamide cure systems for general purpose polymers (NR, NBR, SBR and EPDM). In IIR it results in extremely fast curing.
- Perkacit TDEC is non-staining and non-discoloring. It can be used as a primary accelerator in some continuous cure applications.
- Using Perkacit TDEC in sulfur vulcanization results in increased tensile strength and modulus.
- It should be noted that in the application of Perkacit TDEC N-nitrosodiethylamine can be formed by the reaction of diethylamine, a decomposition product, with nitrosating agents (nitrogen oxides).
- Perkacit TDEC is regulated for use in articles in contact with food as specified under BgVV XXI, Category 4. Perkacit TDEC is not regulated for use in FDA food contact applications. |
