TSR117 Silicone
ELEVATES THERMAL RESISTANCE AND ELECTRICAL PROPERTIES
Helping deliver heat, chemical and weather resistance to paints, TSR117 silicone can also help provide electrical insulating properties. In fact, insulation varnishes employing TSR117 coating have met class H insulation requirements for electrical devices. TSR117 silicone coating can be cured at high temperature; or, with the help of a catalyst, undergo low-temperature cure and room-temperature drying.

DOWNLOADMore About TSR117 Silicone
TSR117 silicone resin is a methylphenyl silicone solution in xylene, which cures to medium hardness. In mechanical film testing, a film of 30 - 40 µm thickness cured at high temperature demonstrated hardness (Sward rocker test) of 50 and Erichsen indication of 8 mm. Good results were obtained in cross cut adhesion tests, and a bend test demonstrated flexibility when the sample was over a 3 mm diameter mandrel.
As an insulating varnish, TSR117 silicone coating has been used to make flexible mica and glass mica tapes and sheets for Class H insulation of electrical devices. It can also be considered for use as a coil impregnating material. For flexible mica and glass mica sheets, TSR117 silicone coating generally can be applied by dipping, brushing or spraying.
