Appearance (uncured): Straw yellow to brown liquid
Components: One component – requires no mixing
Cure: Room temperature with activator
Typical Properties of Uncured Material
Specific Gravity @ 25°C: 1.02
Viscosity, Brookfield – RVT, 25°C, mPa·s (cP):
–Spindle 6, speed 20 rpm: 15,000 to 38,000
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 737 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 the shear strength developed with time on grit blasted steel lap shears at different controlled gaps and tested according to ISO 4587. (Activator 737 applied to one surface).
Typical Performance of Cured Material
Cured for 24 hours @ 22°C, Activator 737 or 7386 on 1 side.
Lap Shear Strength, ISO 4587:
Steel (grit blasted): N/mm² ≥15 (psi) (≥2,900)
Tensile Strength, ISO 6922:
Steel pin (grit blasted): N/mm² 26 (psi) (3,770)
