Master Bond Supreme 45HTQ-4 is a two component, toughened, silicon carbide filled epoxy for high performance bonding, sealing and casting. It is a specialty type system that can be used most notably in downhole applications. In fact, it can be used in a number of oil processing situations, as well as in other industrial operations. Supreme 45HTQ-4 has an easy to use 100:30 mix ratio by weight and requires oven curing at 250-350°F. (Various curing options appear in the table below.) This system’s working life is very long; 12-24 hours at room temperature. It is 100% reactive and does not contain any solvents or diluents. It has low shrinkage upon curing and is highly dimensionally stable. Supreme 45HTQ-4 is very special in that it combines exceptional chemical, temperature and abrasion resistance. It bonds well to a wide variety of substrates, including metals, composites, ceramics and many rubbers and plastics. Its service temperature range is from -100°F to +450°F and it is capable of withstanding rigorous thermal cycling. It is especially useful as a coating system. The color of both Parts A and B is gray. Supreme 45HTQ-4 can be specified in specialty type applications in oil and chemical processing, aerospace and specialty OEM when the distinctive properties mentioned previously are desirable.
