Activator for the OliBOND bonding system changing the polimerisation procedure from light-cured to dual cured. It works perfectly in the root canal. It is enough to add a special activator to the basic version of OliBOND that will activate chemical polymerisation. Such an OliBOND / OliActivator mixture can be applied with chemically- and dually-curing materials as well as during procedures where the use of light is limited or impossible.
