Master Bond Polymer System Supreme 33 is a unique room temperature curing toughened epoxy adhesive/sealant, offering exceptionally high temperature resistance without having to heat cure, although heat curing is optional for accelerated cures. This innovative system offers high bond strength, both shear and peel, along with excellent sealing properties for service from -80°F to +425°F. It has a convenient mix ratio of 100/70 by weight along with a moderate working life. This toughened system has superior impact, thermal shock and stress fatigue cracking resistance. It is 100% reactive and contains no solvents, diluents, or hazardous ingredients. 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. Adhesion to metals, glass, ceramics, wood, vulcanized rubbers and many plastics is excellent. The hardened adhesive is an electrical insulator. Color of part A is gray, part B is amber. Supreme 33 offers the convenience of a room temperature cure with exceptionally high temperature resistance and is widely used in the electronic, electrical, computer, construction, metalworking, automotive and chemical industries. In addition, the Supreme 33 has exceptionally good dimensional stability and very low shrinkage upon cure.
