Delayed-action sulphenamide accelerator

Product overview

CBS is a sulphenamide accelerator that combines delayed action with a fast cure once vulcanisation begins — precisely the profile needed for thick or complex parts that must fill the mould before cross-linking starts.

Valkacit CZ/C is the branded presentation of this widely used accelerator, valued for reliable scorch delay and clean, non-staining behaviour.
