Thermally Conductive Adhesives

Master Bond manufactures one and two component thermally conductive adhesives. They include epoxies, silicones and other elastomeric systems. Special formulations for unusual service conditions are available. They include serviceability to 500°F, at cryogenic temperatures, and in high vacuum environments as well as systems that are easily repairable. Designed for easy application, these compounds can be purchased in convenient packaging. They are used on heat sinks, fan sinks, package lids, motor controls, multiplexers, sensors, power semiconductors and thermistors. Toughened systems have been successfully employed in applications requiring resistance to shock, vibration and thermal cycling.

Low Outgassing Adhesives

Low-outgassing adhesives are those that do not release a lot of volatiles or other chemical compounds. Other than space systems, the most common applications for low-outgassing products are those that involve optical components, which can be clouded or fogged by outgassed chemical compounds. Outgassing can also negatively affect sensitive electronics. Semiconductor manufacturing processes can be very sensitive to outgassing material systems. Semiconductor manufacturing and commercial vacuum processes can also suffer from outgassing issues.

Master Bond has developed various low outgassing epoxy resin based adhesive systems to meet the maximum 1% TML and maximum 0.1% CVCM acceptability criteria as outlined in ASTM E595-93. Some of these have been tested by NASA authorized facilities while others have been independently tested. These adhesives comprise both two and one component compositions requiring either ambient or elevated temperature cures as specified below. These "low outgassing" epoxy adhesive compounds are manufactured with exceptionally high quality standards in order to assure reproducible high performance even under the most demanding service conditions.

Cryogenic Adhesives

Master Bond offers a wide range of versatile, high performance epoxy formulations designed to withstand the severe conditions found in cryogenic environments. They are available as one or two part systems, requiring either ambient or elevated temperature cures as specified below. When fully cured, these adhesive/sealants offer excellent physical strength properties, long term durability, superb chemical resistance, as well as high bonding strengths to both metallic and non-metallic substrates.

UV Curable Adhesives

Master Bond's range of UVcurable bonding, sealing, coating and potting & encapsulation compounds are single component and also require no weighing or mixing prior to use. They are designed to speed productivity, eliminate waste, save energy, increase efficiency and improve reliability. UV curable epoxies, polyurethanes, polyesters and acrylics are available. Grades vary in viscosity, cure speed, hardness, strength, chemical resistance, thermal stability, electrical insulation, optical properties, etc. Environmentally safe, they emit no volatiles or vapors during cure. They remain stable even after prolonged storage at room temperatures until exposed to a UV light source. This eliminates pot life problems. Remarkably fast curing with standard UV cure equipment, these systems will greatly enhance. In most applications, cure speeds within a couple of seconds is common. This removes transient thermal exposures when adhering heat-sensitive substrates.
