Master Bond's Supreme 33 two-component epoxy resists thermal cycling, thermal shock and impact
Formulated for structural applications in extreme environments with temperatures from -80° F to +425° F, Master Bond Supreme 33 is designed to resist thermal cycling, thermal shock and impact. This two-component epoxy offers structural bond strength to a variety of substrates including metals, glass, ceramics, wood, vulcanized rubbers and plastics. Supreme 33 is also engineered to resist chemicals including water, oil and organic solvents.
Supreme 33 has a mix ratio of 100 to 70 by weight or 1 to 1 by volume. It cures at room temperature in 48 to 72 hours. This reactive epoxy does not contain any solvents or diluents, has dimensional stability and features low shrinkage upon cure. It produces bonds with a shear strength of 2,500 psi, a tensile shear of 7,500 psi and a T-peel strength of 15 pli. With a volume resistivity of 1014 ohm-cm, a dielectric strength over 400 volts/mil and a dielectric constant of 3.8 at 75° F, Supreme 33 is also an electrical insulator.
