How MACS Ultrafilm Prevents Corrosion in a Cooling System

MACS Ultrafilm works by preventing air, water and salt from contacting the metal surface.

MACS Ultrafilm clings to all surfaces when injected into the cooling system by forming an ultra thin barrier which displaces and repels water. This barrier is impervious to water and air, but is slowly broken down by the action of agitated salt water, dirt and sand. Also, it dissolves and neutralises salt deposits, before reforming on parent metal for ongoing protection.

The agents contained in MACS Ultrafilm perform the following functions:

  • Petroleum Distillates: Metal conditioner, lubricant, helps repel water.
  • Corrosion Inhibitors: Form the basis of the barrier.
  • Oiliness Improvers: Help to maintain and strengthen the barrier; lubricant.
  • Wetting Agents: Ensure good coverage of the barrier; perform the main cleaning function.
  • Anti Oxidants: Maintain product integrity and help with corrosion inhibition.

MACS Ultrafilm protects all common metals.
