Deovulc TP 4-75 is an accelerator based on zinc dialkyldithiophosphate absorbed on a silica carrier. It is most effective for vulcanizates based on EPDM or diene rubber. It can also be used in combination with all common accelerators.

Deovulc TP 4-75 generates a short flow period and vulcanization time in diene rubber or EPDM. It has high solubility in rubber, easy to handle and incorporate, and is suitable for light color articles without staining or blooming. Deovulc TP 4-75 can be used as nitrosamine-free accelerator. Typical dosage is 1.5-4.0 phr.
