| About |
|---|
| RTVS 11 is a low viscosity, multi-purpose compound, designed for use as a potting, encapsulating, sealing and mold making material. Due to its excellent electrical properties, the RTVS 11 is used extensively as a high voltage potting compound, as well as an encapsulating compound for delicate circuitry. The RTVS 11 can be used with various curing agents, thus varying pot life, cure time, mix ratios and cure conditions. (See RTVS Catalyst Selector Guide).&& |
