GR-BIO
Biodegradable industrial grease

Description

The GR-BIO is a high performance biodegradable grease.

Characteristics and Benefits

 The GR-BIO unique formulation includes such elements as:

  • - Overbased calcium sulfonate complex;
  • - Superior quality biodegradable fluid.

This formula, maid from the latest thickener technologies, allows GR-BIO to reach an exceptional level of performance. It is marked by its exceptional mechanical stability, very high load carrying properties, and particularly excellent resistance to water and corrosion.

Types of Application

The GR-BIO performs best in applications that are environmentally sensitive and where the temperatures are below 100°C.

Directions for Use

Always use GR-BIO biodegradable grease in reference to the equipment manufacturer's manual.

Warning

Whenever performing a grease change, make sure to validate the compatibility of the various greases used (refer to PROLAB's grease compatibility chart).
