Features and Benefits

 N/A
  • Helps to minimizes cobalt build-up which can lead to health hazards and tool/part failures
  • Can improve surface finish of components through reduced cobalt dissolution from the tungsten carbide binder matrix
  • Low foam in recommended water conditions (see details below)
  • Extended fluid life can help to reduce maintenance and downtime
  • Good anti-corrosion properties to protect machine tools and parts
  • Rejects tramp oil to the surface of the fluid for easy removal
  • Settles chips quickly to prevent grinding wheel build-up and maintain a clean working environment
  • Formaldehyde releasing agent and nitrite free which help you to fulfil aspects of legislative requirements and waste treatment requirements where applicable

Storage and Handling

 N/A To avoid product deterioration always keep the container/drum tightly sealed. Store the product in a cool, dry place away from direct sunlight. Prevent exposure to frost and avoid water ingress. For optimum product stability, it is preferable to store the product indoors between 5°C and 45 °C / 41°F and 113°F.
