HENKEL CORP.: Halogen-Free Adhesives (4/3/09)
In response to industry initiatives and legislation designed to protect the environment from halogenated materials, Henkel Corp. has introduced a new line of Loctite®adhesives and sealants that meet the requirements of IPC IEC #61249-2-21. Used primarily in handheld electronics such as cell phones, PDAs, notebook/laptop computers and hard disk drives, these adhesives are formulated to contain less than 900 ppm bromine and chlorine, and 1500 ppm total halogens. Often halogen levels in these products are undetectable.
The full line of Loctite halogen-free adhesives includes more than 30 products in a range of technologies including cyanoacrylates, light-cure cyanoacrylates, epoxies, urethanes, UV acrylics, silicones, hot-melts, two-part acrylics and anaerobics. These materials are used for bonding, sealing, gasketing and mounting a range of components including connectors, keypads, cameras, microphones, speakers, trim, emblems, frames, screens, latches, magnets, hinges, cases, batteries, head gimbals, head stacks, sliders, and bearings.
In addition to halogen-free materials, Henkel offers technical and engineering support to meet lead-free processing requirements.
