Material Notes:
Description: Master Bond Polymer System Supreme 33 is a unique, room temperature curing, toughened epoxy adhesive/sealant, offering high temperature resistance. This innovative system offers high bond strength, shear and peel, along with sealing properties for service from -80°F to +425°F. It has a convenient mix ratio of 100:70 by weight or 1:1 by volume along with a moderate working life. This toughened system has good impact, thermal shock and resistance to thermal cycling. It is 100% reactive and contains no solvents or diluents. A non-drip version called Supreme 33ND is also available. Supreme 33 produces durable, high strength, and tough bonds which are remarkably resistant to thermal cycling and chemicals including water, oil and many organic solvents. Its adhesion to metals, glass, ceramics, wood, vulcanized rubbers and many plastics is excellent. The hardened adhesive is a superb electrical insulator. Color of the Part A is amber, the Part B is brown. Supreme 33 offers the convenience of a room temperature cure with high temperature resistance. It is widely used in the electronic, electrical, aerospace and OEM type industries. Supreme 33 will cure at room temperature although to optimize properties, the best cure schedule is overnight at room temperature followed by a few hours at 150-200°F. In addition, the Supreme 33 has exceptionally good dimensional stability and very low shrinkage upon cure. Product Advantages: Convenient mixing: non-critical mix ratio (100:70) by weight or 1:1 by volume Easy application: contact pressure only required for cure: adhesive spreads evenly and smoothly Versatile cure schedules: ambient temperature cure or fast elevated temperature cures as required High bonding strength to similar and dissimilar substrates from -80°F to +425°F Good durability, dimensional stability, thermal shock and chemical resistance Excellent thermal cycling capabilities Good retention of strength at high temperature.
