Cure Speed vs. Temperature
The rate of cure will depend on the ambient temperature. The
graph below shows the shear strength developed with time on
grit blasted steel lap shears at different temperatures and
tested according to ISO 4587.

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 shear strength developed
with time on grit blasted steel lap shears using
Activator 7471™ and 7649™ and tested according to ISO
4587.
