Formulated for structural applications in extreme environments with
temperatures from -80 to +425F, Master Bond
Supreme 33 offers resistance to thermal cycling, thermal shock and impact.
This toughened, two-component epoxy offers high structural bond strength 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.
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. For optimal performance, the
suggested schedule is curing overnight at room temperature followed by 2 to 3
hours at 150 to 200F. This 100 percent reactive epoxy does not contain any
solvents or diluents, has dimensional stability and features low shrinkage upon
It produces high performance bonds boasting a shear strength over 2,500 psi,
a tensile shear strength greater than 7,500 psi and a T-peel strength exceeding
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 75F, Supreme
33 is an electrical insulator that is widely used in the electronic,
electrical, aerospace and OEM industries. Supreme 33 is also available in a
non-drip version called Supreme 33ND.
