Wed, 04/01/2009 - 10:53am
In response to industry initiatives and legislation designed to protect the environment from halogenated materials, a line of Loctite adhesives and sealants are offered that meet the requirements of IPC IEC #61249-2-21. Used primarily in handheld electronics, these adhesives are formulated to contain less than 900 ppm bromine and chlorine, and 1,500 ppm total halogens. Often halogen levels in these products are undetectable. The full line of 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.
