Structural Adhesive

By Design Engineering Staff   


Master Bond’s Supreme 33 adhesive designed for high temperature resistance.

Master Bond introduced Supreme 33, a two-component epoxy formulated for structural applications in extreme environments with temperatures from -80°F to +425°F. With resistance to thermal cycling, thermal shock and impact toughened, the epoxy bonds to a wide variety of substrates including metals, glass, ceramics, wood, vulcanized rubbers and many plastics. Supreme 33 also resists chemicals including water, oil and many organic solvents.

The epoxy has a mix ratio of 100 to 70 by weight or 1 to 1 by volume and cures at room temperature in 48 to 72 hours. Once cured, It produces bonds with a shear strength over 2,500 psi, a tensile shear strength greater than 7,500 psi and a T-peel strength exceeding 15 pli. Bonds also exhibit volume resistivity of 1014 ohm-cm, a dielectric strength over 400 volts/mil, and a dielectric constant of 3.8 at 75°F.
