Henkel introduces range of thermally conductive adhesives
Dec 14, 2005
The electronics group of Henkel has launched the Loctite Bead-on-Bead thermally conductive adhesives products range.
Based on proven, proprietary structural adhesive technology, the products represent a new concept in the bonding of heat-dissipating electrical and electronic devices to conventional heat sinks and spreaders.
Loctite Bead-on-Bead is a unique chemistry for a two-part acrylic adhesive. Instead of following the traditional method of premixing the two parts and managing the inherent pot-life issues associated with this, manufacturers are now able to apply each part independently to the component. With the new product range, mixing occurs only when the two items to be bonded are joined together.
"The introduction of Loctite Bead-on-Bead technology is an important development for the electronics industry and the process benefits are immense," explains Jimmy Earle, Global Product Manager for Thermal Interface Materials at Henkel. "The range presents significant advancements in adhesive technology, offering superior levels of thermal performance and reliability for manufacturers increasingly moving towards more demanding applications. For increased manufacturing throughput, reliability and cost-effectiveness, Loctite Bead-on-Bead looks set to become a dominant adhesive technology."
Available in product types Loctite 3875 and Loctite 3876, the thermally conductive adhesives are marketed with or without 7 mil glass spacer beads to provide controlled spacing and electrical isolation from heat sink. Featuring a wide selection of process benefits, the new range of thermally conductive adhesives form a solid addition to Henkel's range of high performance thermal interface materials to meet the needs of design and manufacturing engineers.
