Designed for the efficient heat transfer from one area to another, heat exchangers are widely used in a variety of industries such as power generation, food processing, automotive, chemical, HVAC, mining and oil processing. Heat from a fluid passes to a second fluid without coming into direct contact. They are usually classified in one or two ways, depending on their flow arrangement--either by parallel flow or counter flow (which is able to transfer more heat). Master Bond's wide range of thermally conductive, high temperature resistant, toughened adhesives, sealants, coatings and encapsulation compounds are frequently selected as the right choice for heat exchanger assembly.
Careful consideration of flow rate, temperature differentials, ratio of heat transfer area to volume are necessary to select the proper formulation to optimize performance and best meet design parameters. Our products have proven effective in sealing tubes into end plates. They are also used for bonding heat exchange fins, bonding rubber gaskets and potting/sealing flutes in cooling devices. Most important they adhere well to metallic substrates such as aluminum, brass, copper, steel, stainless steel and many dissimilar substrates. As a substitute for welding, brazing especially when processing is a concern, these formulations offer the benefits of being easy/convenient to handle, easy to dispense, have versatile cure schedules and avoid pin prick weld holes or warping. These electrically insulative compounds prevent galvanic and crevice corrosion. They also are noted for enhancing the aesthetic appearance of the heat exchanger and offer manufacturers cost saving when purchased in small or larger quantities.
