Application: ZDTP is a fast curing secondary accelerator for NR and EPDM. When used in NR to improve reversion resistance, care must be taken to select the level of ZDTP to obtain the best compromise between scorch and reversion resistance. Since ZOTP is non-blooming and non-discoloring. It can be used in translucent, fast curing NR shoe sole compounding.
