Low Viscosity Silicone Fluids are used in a variety of instruments, gauges, sensors and meters to observe and management temperature, strain, vibration movement & humidity. Their low viscosity, low pour points, low viscosity change at temperature and inertness make them extensively used for extreme low temperature applications. These properties ensure that the gauges/instruments/meters and sensors, in which they are used, present the most correct studying in essentially the most adverse circumstances. Nevertheless, this materials also has some drawbacks. For instance, Rutile Titanium Dioxide silicone just isn't oil resistant for long durations, and it will probably swell after long durations of contact with oil or petroleum, though there are extra oil-resistant varieties. Silicone can also be not abrasion or tear-resistant and can get stiffer at larger temperatures. What Are the Types of Silicone?

Fluorescent dyes and shade coated micas are not normally in scope for this test as they don't seem to be real pigments with Coloration Index as such.
