Featuring a combination of thermal conductivity and electrical insulation properties, Master Bond Supreme 3CCM-85 is a single component epoxy initially designed for glob top and chip coating applications. However, this system can also be utilised for encapsulation and bonding. Supreme 3CCM-85 cures within two to three hours at 80-85°C, which is advantageous for use on heat sensitive components and substrates. 

Supreme 3CCM-85 is a toughened adhesive system, that bonds well to a variety of similar and dissimilar substrates. It has a high volume resistivity of more than 1014 ohm-cm and a thermal conductivity of 5-10 BTU•in/ft2•hr•°F [0.72-1.44 W/(m•K)]. The system is serviceable from -73 to +177°C.

Since Supreme 3CCM-85 is not premixed and frozen and has a very long open time at room temperature, it is more convenient to handle and store than typical two component glob top systems. This opaque black compound has a thixotropic paste-like consistency and is easy to apply either manually or with an automated dispenser. 

Master Bond Supreme 3CCM-85 is available for use in common size syringes ranging from ten to 30cc as well as in standard size containers.

Master Bond Supreme 3CCM-85 is a multifunctional system for glob top, encapsulation and bonding applications featuring high thermal conductivity, electrical insulation and toughness.
