　　TYPICAL CURING PERFORMANCE

　　Cure Speed vs. Substrate

　　The rate of cure will depend on the substrate used. The graph

　　below 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)
