Non-Premixed And Frozen, One Part Epoxy For Chip Coating

Featuring a combination of thermal conductivity and electrical insulation properties, Master Bond Supreme 3CCM-85 is a new single component epoxy initially designed for glob top and chip coating applications. However, this system can also be utilized for encapsulation and bonding. Supreme 3CCM-85 cures within 2-3 hours at 175-185°F [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 -100°F to +350°F [-73°C 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 10 cc to 30 cc as well as in standard size containers.
