Typical Curing Performance

Cure Speed vs. Substrate
The rate of cure will depend on the substrate used. The graph shown in the data sheet below shows the shear strength developed with time on grit blasted steel lap shears and tested according to ISO 4587. (Activator 7387 applied to one surface).

Cure Speed vs. Bond Gap
The rate of cure will depend on the bondline gap. The following graph shown in the data sheet shows the shear strength developed with time on grit blasted steel lap shears at different controlled gaps and tested according to ISO 4587. (Activator 7387 applied to one surface).

Typical Performance of Cured Material
