Applications

HY 103 is a high performance water soluble polyalkylene glycol basestock with a viscosity of 52 mm2/s at 40 °C. HY 103 finds extensive application when manufacturing and formulating various water soluble lubricants for example:

• Gear, bearing and calender lubricants

• Compressor lubricants

• Metal working fluids

Storage

▪ HY 103 should be kept tightly sealed in a dry place in its tightly sealed original packaging. Storerooms must not be overheated.

▪ HY103 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.

▪ HY103 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, HY103 has a shelf life of five years in its original packaging.
