Thermally Conductive, Electrically Insulative Epoxy Delivers Low Exotherm for Large Castings and Potting Applications
Master Bond EP39MAOHT is a room temperature curing system for demanding bonding, sealing, coating, potting and encapsulation applications. “It is a versatile product that combines convenient handing, good flow, thermal conductivity, electrical insulation and high temperature resistance,” said Robert Michaels, vice president of technical support. “Its toughness lessens the chance of stress cracking when thermally…
One Part, Toughened Epoxy for Specialty Dam-and-Fill Encapsulation
Master Bond Supreme 3HTND-2DM is a rapid curing, toughened, one part epoxy system used for the dam-and-fill method for chip-on-board encapsulation. Essentially, there are two methods to protect chips and their wire bonds. One method is referred to as glob top, where the encapsulating system is dispensed and applied directly to the area to be…
Structural bonding solutions for plastics
By Rachel B. Nashett, Application Engineer-Henkel Corporation Plastics have become an integral part of everyday life. It would be difficult to identify a manufacturing process that does not use plastics. Even products that appear to be composed exclusively of metals are usually coated, sealed, or adhesively joined using polymeric materials which improve the performance, appearance,…
