Composition: 80% zinc-diethyl-dithiocarbamate, 20% EPDM/EVA binder and dispersing agents Use Characteristics: Konson® ZDEC-80 causes very rapid vulcanization of natural and synthetic rubbers, e.g. SBR, NBR and EPDM. The addition of thiuram and thiazole accelerators can retard the start of the vulcanization and, at the same time, increase processing safety. Konson®ZDEC-80 provides a longer scorch time and a faster total curing rate than Konson®ZDBC-80. Konson®ZDEC-80 recieves an additional activation from basic accelerators. Konson®ZDEC-80 is also used in small amounts for secondary acceleration and activation of mixes which are going to be cured with mercapto or thiuram accelerators. Konson®ZDEC-80 gives very good tenslie and resilience properties. For improving the resistance to ageing especially of NR and IR 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 ZDEC is assured. Dosage levels: NR:0.3 - 1.0 phr; as secondary accelerator: 0.1 - 0.2 phr; SBR and NBR:0.8 - 1.2 phr; as secondary accelerator: 0.1 - 0.2 phr. Applications: Suitable for technical rubber articles based on NR, EPDM, IR, SBR, NBR or IIR.. Information provided by Konson® |
