Typical resins used for electronic adhesives are epoxies, polyurethanes, acrylics and silicones. AEROSIL® R 208, AEROSIL® R 202 and AEROSIL® R 805 are very effective thixotropes for epoxy electronic adhesives, and AEROSIL® R 208 and AEROSIL® R 202 for polyurethane adhesives. The hydrophilic grades AEROSIL® 200 and AEROSIL® 300 are especially used for acrylics and silicone electronic adhesives. The use of AEROSIL® R 711 and AEROSIL® 7200 makes it possible to improve even further the mechanical properties of radical curing electronic adhesives.
