Raw material characteristics of ZDMC-75:


Use Characteristics

1. ZDMC-75 is an ultra accelerator for the vulcanization of natural and synthetic rubbers, e.g. SBR, NBR and EPDM. The addition of thiuram and thiazole accelerators retards the start of the vulcanization and increases processing safety.                                          
2. ZDMC-75 gives a longer scorch time and a faster total curing time than ZDBC-75, ZDEC-75 and ZEPC-75. ZDMC-75 receives an additional activation from basic accelerators. It is also used in small amounts for secondary acceleration with thiazole and sulfonamide and for the activation of mixes, which are going to be cured with mercapto or thiuram accelerators.                  
3. ZDMC-75 provides very good tensile and resilience properties. For improving the resistance to ageing, it is recommended to add antioxidants.


Processing Advantages
The thermoplastic, excellent compatible EPDM/EVA binder which is combined with active dispersing promoters allows much more easily and quickly incorporation and excellent dispersion in the rubber mixing. In this way, optimal activity of the effective ZDMC is assured.


Dosage:

NR: 0.3  0.8 phr; as secondary accelerator: 0.05 - 0.3 phr;

SBR and NBR: 0.8 - 1.2 phr; as secondary accelerator: 0.05 - 0.3 phr.


Applications
ZDMC-75 is non- staining, non discoloring and dispersed well, thus suitable for technical rubber articles based on NR, EPDM, IR, SBR, NBR or IIR, especially for light-colored articles and transparent articles.
