HY-BIO
lubricant for hydraulic systems

Description

PROLAB's HY-BIO is the best-performing biodegradable lubricant for hydraulic systems on the market.  Its unique formula, exclusive to PROLAB, provides it with exceptional properties which outclass all mineral and synthetic biodegradable hydraulic lubricants as well as many of the standard mineral oil hydraulic lubricants.

Characteristics and Benefits

PROLAB's HY-BIO ecological biodegradable lubricant for hydraulic systems is a unique blend of 100% synthetic high-performance oil and superior quality antioxydant. HY-BIO provides superior thermal stability, excellent hydrolytic resistance (very little breakdown when exposed to water), as well as exceptional resistance to load, oxidation (between 5000 and more than 10000 hours) and corrosion combined with excellent anti-foaming properties. HY-BIO's very low pour point combined with a high viscosity guarantees better lubrication and superior performance in all temperatures.

PROLAB's HY-BIO is environmentally friendly: biodegradable and ecological, it contains no heavy metals, organochlorines or nitrous compounds.

Furthermore HY-BIO is safe to use, not subject to SIMDUT regulations, and is available in five ISO grades: #15, # 22, # 32, #46 and # 68.

Types of Application

PROLAB's HY-BIO is essential in all hydraulic systems subject to environmental risks of accidental spills or leaks such as near bodies of water, or in wharf facilities, maritime equipment, forestry, agriculture, etc. Also, when low temperature conditions are encountered, HY-BIO # 22 will become an excellent choice.

Compatibilities

HY-BIO are compatible with almost all of elastomer joints of nitrile types, Hythane and polyesters.

Directions for Use

Follow the manufacturer's instructions for the lubrication of the specific piece of equipment.

Notes

For better results, it is highly recommended to use PROLAB's DE-25 Decontaminant prior to using a new lubricant.

The use of environmentally friendly products minimizes the negative consequences following an accident that could otherwise prove to be very costly and damage your corporate image.

Warning

Verify compatibility of elastomer seals.HY-BIO should not be used as transmission fluid.
