SILICONE-VG is a stiff non-melting grease like Silicone material. It maintains its consistency over a wide temperature range of -40°C. to 200°C. It may from a solid gel if subjected to temperature 250°C or above for a long periods. Its low volatility very low vapor pressure of the base, chemical resistance, relatively resistance over a wide temperature range and sealing ability, make it an ideal sealant for high vacuum and high pressure systems and, sealant-cum-lubricant for chemical processing equipment. A P P L I C A T I O N As a sealant and lubricant glass-joints and stop-cocks in high vacuum and high temperature systems as well as in ordinary systems. In pressure lubricated plug valves, control valves and ceramic plug cocks. In valves of water-softener. In fire-extinguishers to keep the valves dependably operable for long period despite sever temperature conditions and corrosive atmosphere. As a sealant on floating telephone batteries. To lubricate synthetic rubber O-Rings, seals and gaskets. Its high tack may be taken advantage of, in holding rubber and other parts in position during assembly of certain parts. As a release agent for epoxy, polyvinyl chloride, polyester resins and other plastics. Normally it is used only when common release agents including other Silicone release agents fail. |
