Applications
▪ HY110 is a high performance water soluble polyalkylene glycol lubricant basefluid with a viscosity of 2025 mm2/s at 40 °C.
▪ HY110 shows high thermal and high shear stability. The high viscosity and low volatility of HY110 makes it very suitable for high temperature lubrication.
▪ HY110 find extensive application in quenchants, metalworking fluids and water based hydraulic fluids formulations, demonstrating excellent shear stability and providing good lubricity to the finished fluids.
▪ HY110 is soluble in water at temperatures below 75 °C.
Storage
▪ HY110 should be kept tightly sealed in a dry place in its tightly sealed original packaging. Storerooms must not be overheated.
▪ HY110 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.
▪ HY110 must be blanketed with nitrogen if stored in heated tanks (at 50 – 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, HY110 has a shelf life of five years in its original packaging.
