Description
Color: Gray (mixed) Base: Modified epoxy Form: Two-part paste Weight: 40 lbs./cu. ft. nominal Volatile Loss on Cure: Less than 1% (1 hour @ 350°F [177°C]) Cure Cycle: 250°F to 350°F (121°C to 177°C) for 1 hour with a 10°F (-12°C)/minute warmup rate. (350°F [177°C] for best elevated temperature resistance.) Product Performance Porosity: A cured 2" x 2" x 1" test block did not absorb JP-4 under a pressure of 30 psi for 48 hours. Mechanical Properties Compression Strength: 1" x 1" x 2" samples were cut from a cured test block of Scotch-Weld EC-3500 B/A adhesive. Compression was run with force applied to the 1" square surfaces. Compression Rate: 0.02"/minute Cure Cycle: 250°F (121°C), 1 hour, 50 psig, 10°F (-12°C)/min. warmup rate Test Temperature Compressive Strength 75°F (24°C) Min. 6000 psi 350°F (177°C) Range: 6000-9000 psi Shear Strength: Shear strength was determined using a tongue and groove test block as shown below. Metal: 2024 T-3 bare aluminum Load Rate: 0.1"/min. jaw separation Cure Cycle: 350°F (177°C), 1 hour, 50 psi, 10°F (-12°C)/min. warmup rate
