Plexus® Gap Filler SL6200 is a two-component, fast curing, gel type gasket filler, with a thermal conductivity of 2.0 W/m·K. It is suitable for thixotropic and low stress applications, designed to provide enhanced thermal management for advanced vehicles battery, automotive electronics and communications equipment etc. It provides better reliability and rework ability than traditional materials. This product is high adaptable to materials, easy to use, which can eliminate assembly tolerances and protect welding spot and other components for stress-free on assembly line. This product can be applied in automation control supply and fully automatic assembly, which corresponds to the thermal interface of Industry 4.0. It can significantly reduce the overall manufacturing cost for its good rework ability and repairability.
