Use Characteristicsthe curing accelerator Konson DPG-80 gives a very long scorch time and a relatively slow full cure. It causes slight discolouration and cannot be used in light-coloured articles, except as an activator. When Konson DPG-80 is used on its own the resistance of the vulcanizates to hot air and oxygen is poor (requiring the use of effective antioxidants). Accelerators of the mercapto type are strongly activates by Konson DPG-80. In IIR and EPDM compounds, Konson DPG-80 has only little effect.

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