Use: Clearco Low Viscosity Pure Silicone fluids are clear, colorless, and odorless 100% linear polydimethylsiloxanes (CAS# 63148-62-9) They range in viscosity from 5cSt to 20cSt (centistokes) and are characterized by their low pour points, low surface tensions, low viscosity change at temperature (VTC), excellent lubricity, high dielectric strength , wide service temperature range and inertness to virtually all substates.
A primary use is as a vehicle or ingredient in a number of personal care products due to their high spreadability, low surface tension, subtle skin lubricity, and non-greasy feel. Applications include: antiperspirants, skin creams, skin lotions, suntan lotions, bath oils, hair care products etc ...see also Cosmetic Grade Silicones
Clearco Low Viscosity Silicone Fluids also possess high resistance to shear, high water repellency, low vapor pressure, and low reactivity. They are excellent lubricants for plastics, foams and rubbers. Due to their low pour points and low VTC (viscosity change at temperature), they are excellent choices for low temperature bath fluids ...see also Low Temperature Bath Fluids
Clearco Low Viscosity Pure Silicone Fluids meet Federal Specification VV-D-1078 "Silicone as Damping Fluid". They are used in a wide range of military, industrial and avionic gauges, meters, instruments, and monitoring systems.
Clearco Low Viscosity Silicone Fluids are exempt from Federal VOC regulations, including California (CARB) and OTC regulations. They are HAP free and will not contribute to ozone-depletion and global warming. In addition, they meet RoHS Compliancy.
Clearco Super Low Viscosity Silicone Fluids are California VOC Expempt and will not contribute to ozone-depletion and global warming. In addition, they meet RoHS Compliancy.
