Typical Curing Performance

Cure Speed vs. Substrate
The rate of cure will depend on the substrate used. The graph shown in the data sheet shows the shear strength developed with time on grit blasted steel lap shears compared to different materials and tested according to ISO 4587. (Activator 7649 applied to one surface).

Cure Speed vs. Bond Gap
The rate of cure will depend on the bondline gap. The graph shown in the data sheet shows shear strength developed with time on grit blasted steel lap shears at different controlled gaps and tested according to ISO 4587. (Activator 7649™ applied to one surface)

Cure Speed vs. Temperature
The rate of cure will depend on the ambient temperature. The graph shown in the data sheet shows shear strength developed with time at 120°C on grit blasted steel lap shears and tested according to ISO 4587.
