|---|
| RTVS 27 LV is a low viscosity, general purpose, reversion resistant RTV Silicone Compound. RTVS 27 LV finds use in commercial potting/casting application. RTVS 27 LV’s one-to-one ratio by weight or volume makes it ideal for dispensing equipment or unskilled labor. With the ability to cure rapidly at elevated temperatures, RTVS 27 LV can be processed quickly in production situations.&& |
