Cure Speed vs. Temperature
The rate of cure will depend on the temperature. The graph
below shows the breakaway strength developed with time at
different temperatures on M10 steel nuts and bolts and tested
according to ISO 10964.

Cure Speed vs. Activator
Where cure speed is unacceptably long, or large gaps are
present, applying activator to the surface will improve cure
speed. The graph below shows the breakaway strength
developed with time on M10 zinc dichromate steel nuts and
bolts using Activator 7471™ and 7649™ and tested according
to ISO 10964.
