N,N'-diphenyl guanidine acc. to specification with elastomer binder and dispersing agents.
Isogran® DPG-80 gives a very long scorch time and a relatively slow full cure. It causes slight discoloration and cannot be used in light-colored articles, except as an activator. When Isogran® DPG-80 is used on its own the resistance of the vulcanizates to hot air and oxygen is poor (requireing the use of effective antioxidants). Accelerators of the Mercapto type are strongly activated by Isogran® DPG-80. In IIR and EPDM, Isogran® DPG-80 has only little effect.
