High Strength Sensor Adhesive

Product News Tuesday, April 13, 2010: Master Bond Inc

Master Bond’s sensor epoxy, Supreme 45HTQ is an extremely stable and durable epoxy for bonding and encapsulating transducers, gauges, actuators and sensors in harsh environments such as those found in downhole applications. The combination of a quartz filler and a special amine compound forms a tough superlative epoxy that will survive the high temperatures and natural gamma radiation found in drilling and extraction operations. When used to attach sensor and transducer elements to a wide variety of substrates, Master Bond’s Supreme 45HTQ is capable of withstanding even the most severe conditions. Its superb resistance to chemicals, especially acids and oils as well as water and steam is ideally suited for this aggressive environment. Also, long term exposures of 205-260°C will not adversely affect the performance of this system.

To ensure accurate pressure and temperature measurements, Master Bond’s Supreme 45HTQ sensor bonding compound has been designed with a low CTE. Its rate of thermal expansion is low 30-35 X 10 -6 in/in°C but it retains remarkable thermal cycling capabilities. Supreme 45HTQ will retain its physical strength properties at doses up to 1010 rads. The physical properties include a tensile strength exceeding 8,500 psi and a compressive strength greater than 20,000 psi. Supreme 45HTQ is available in pint, quart, gallon and 5 gallon container kits.
