Applications
▪ HY101 is a high performance water soluble polyalkylene glycol basestock with a viscosity of 1050 mm2/s at 40 °C.
▪ HY101 is a water soluble lubricant base fluid suitable for a range of industrial lubricant applications.
Storage
▪ HY101should be kept tightly sealed in a dry place in its tightly sealed original packaging. Storerooms must not be overheated
▪ HY101 is hygroscopic with the result of absorbing moisture very quickly. Care needs to be taken to exclude moisture. Drums must be resealed each time they are opened.
▪ HY101 must be blanketed with nitrogen if stored in heated tanks (at < 60 °C) to prevent from coming into contact with air. Constant, gentle stirring helps to prevent discoloration as a result of prolonged contact with electrical elements or external heating coils.
Shelf life:Provided it is stored properly and the drums are kept tightly sealed, HY101 has a shelf life of five years in its original packaging.
