Applications
HY110 is a high performance water soluble polyalkylene glycol basestock with a viscosity of 1000 mm2/s at 40 °C.
HY110 was introduced as a label-free polyalkylene glycol base-fluid, free of any inhalation toxicity hazards.
HY110 exhibits excellent resistance to weight loss under oxidizing conditions, with minimal residue formation. When fully formulated, HY110 offers excellent resistance to loss of viscosity under oxidizing conditions and high shear.
HY110 finds extensive application when manufacturing and formulating various water soluble lubricants for example:
• Gear, bearing and calender lubricants
• Compressor lubricants
• Metal working fluids
Storage
• HY110 should be kept 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 < 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 5 years in its original packaging.
