Deovulc ZO

Deovulc ZO is a Zinc-2-ethylhexanoate and acts as an activator for the vulcanization of natural rubber. The high solubility of Deovulc ZO often provides higher cross-linking density, which leads to improved compression set and dynamic properties. It is possible to partially replace the stearic acid with Deovulc ZO, e.g. in order to avoid blooming.

Deovulc ZO-DL

Deovulc ZO DL is a 67% dry liquid form of Deovulc ZO.

Deovulc OH

Deovulc OH

Deovulc OH is a particularly fine calcium hydroxide, which acts as an acid scavenger and cross-linking activator in fluoroelastomer-based compounds.
