ITW Insulcast® INSULGREASE SG 146LV Silicone Potting/Encapsulation Compound
Categories: Polymer; Thermoset; Silicone

Material Notes: Insulcast® solutions are compounds designed for potting and encapsulating. Insulgrease SG146LV is a soft non-toxic, grease-like compound based on a thickened silicone fluid. Insulgrease SG 146LV is chemically inert and is useful as a release agent and offers excellent lubrication on plastic and rubber surfaces. While not designed for bearing surfaces under heavy loads,it will provide good results for light loads. As it is a silicone, the change in its viscosity over a broad temperature range of -40 to 400 °F is very low, thus preventing runoff or stiffening to the point of unusable. Insulgrease SG 146LV is non corrosive and oxidation resistant. With high dielectric strength and good hydrolytic stability, it is also water repellent and radiation resistant. Insulgrease SG 146LV complies with the ANSI/NSF Standard 61 for drinking water system components. The material also meets FDA requirements for food contact uses under 21 CFR 175.300.
