Potting and Encapsulation Materials
Master Bond Inc. offers a broad line of potting and encapsulation materials designed to protect electronic circuitry and assemblies from potentially damaging conditions such as moisture, various corrosive chemicals, excessive heat, vibration, mechanical impact, thermal shocks and abrasion which might occur while the device is in operation. While the majority of the products offered are epoxies, including both rigid and flexible types, other systems are also available such as polyurethanes and silicone compounds. These systems include two part systems that cure at ambient temperatures or more quickly at elevated temperatures, as well as one part, no mix systems requiring elevated temperature cures. Master Bond's potting and encapsulation epoxies feature outstanding electrical insulation characteristics including high volume resistivity, excellent dielectric strength and low dielectric constants and dissipation factors. Some of the more specialized compounds include epoxies that are flame resistant, thermally conductive and cryogenically serviceable. Master Bond's technical staff will be glad to recommend the product best suited to your particular application's requirements.

Thermally Conductive Products
The recent trend in electronic packaging is for greater functionality in decreasing sizes of circuitry. This phenomenon has caused an urgent need for enhanced heat dissipation and heat sinking without loss of desirable electrical insulation characteristics. Master Bond Inc. offers a wide range of thermally conductive, electrically insulative systems which offer effective solutions to demanding heat dissipation problems. Master Bond manufactures both one and two component thermally conductive systems including epoxies, silicones and other elastomeric systems. Some of the more special systems are serviceable at very high temperatures (500F) or at cryogenic temperatures (4K). Also noteworthy are our NASA approved thermally conductive systems for high vacuum applications. A new Master Bond innovation is our thermally conductive film system, FL901AO, which can be used as an adhesive, sealant and coating. Films are available in a variety of shapes and sizes and offer ease of assembly with minimal waste.

Electrically Conductive Products
Master Bond Inc. offers a broad line of electrically conductive adhesives, sealants and coatings which are widely used in the electronic and electrical industries. They are formulated with metal powders and flakes such as silver, nickel, copper and silver-coated nickel, with silver formulations exhibiting the highest levels of electrical conductivity. Graphite-filled formulations have also been developed for use where metal additives are not desirable. Master Bond offers a number of room temperature curing and low elevated temperature curing, electrically conductive systems for applications where heat-sensitive components must be bonded to circuit boards and other assemblies or for repair of circuitry. Other applications range from the construction of disc drives to die attach and flip-chip processes. Also available are electrically conductive coatings which are widely employed for EMI/RFI shielding of plastic molded parts to prevent undesirable electrical interference. There is also an increasing demand for electrically conductive sealants. Master Bond offers both two and one part conductive sealants. The two part systems are primarily epoxies.
