891-7Dow Corning高真空润滑脂

Dow Corning High Vacuum Grease

High vacuum grease, general lab lubricant use

Dow Corning^® High vacuum Grease is a stiff, non-melting silicone lubricating material which has temperature range of -40ºC to 200ºC. Although it has a good stability at the higher end of the temperature range than most hydrocarbon greases, it shows a higher outgassing rate at room temperature. It can be used for high vacuum systems up to the 1x10^-6 mbar （1x10^-6torr） range. Due to it's initial outgassing, it is recommended to condition vacuum system before use. Not for use in electron microscopes. Also not recommended for use in evaporators which need to be Si free. The Dow Corning^® High Vacuum Grease is the equivalent product to Dow Corning^® 976 of 976V High Vacuum grease. Other applications include lubricant for glass stopcocks, glass joints, glass rubber connections and O-rings on binoculars. Shelf life is 60 months from date of manufacture for unopened containers and stored at normal warehouse conditions.

道康宁高真空润滑脂
高真空润滑脂，一般实验室润滑剂使用

道康宁®高真空润滑脂是一种坚硬，不熔化的有机硅润滑材料，温度范围为-40ºC至200ºC。虽然它在温度范围的较具有比大多数烃类润滑脂更好的稳定性，但它在室温下显示出更高的除气率。它可用于高达1x10-6 mbar（1x10-6torr）范围的高真空系统。由于它的初始除气，建议在使用前调节真空系统。不适用于电子显微镜。也不建议用于需要不含硅的蒸发器。道康宁高真空润滑脂是道康宁®976的976V高真空润滑脂的同等产品。其他应用包括用于玻璃旋塞的润滑剂，玻璃接头，玻璃橡胶连接和双筒望远镜上的O形圈。自未开封容器的生产日期起保质期为60个月，并在正常仓库条件下储存。
