NURCHEM ZDMC-75 is an ultra-accelerator, used either alone or as a secondary accelerator, for the fast vulcanization of natural and synthetic latex and also solid rubber types such as NR, SBR, EPDM, IIR, IR and NBR. It gives a fast cure, high modulus and short scorch times. It provides rubbers with good heat-ageing resistance. It is also an excellent activator for thiazole,
The primary curing agent, however, must be of non-sulfur nature (and is preferably, though not necessarily, a resin-based compound) in order to provide the desired antimicrobial activity for the subject rubber. Furthermore, the primary curing agent may be already incorporated into the unvulcanized rubber during the manufacturing process.
