Examples of this breakdown are the rusting of iron, the corroding of aluminium and the greening of copper. Removing any one of the necessary elements stops corrosion. Whilst impurities cannot be removed, salt, air and water can be prevented from contacting the metal by application of MACS Ultrafilm. Therefore, corrosion occurs during actual use of the boat. Application of MACS Ultrafilm before use protects against corrosion during use.
Salt is deposited onto the cooling channel surfaces.
Just like hard water mineral deposits on the interior of hot water cylinder pipes, salt builds up to insulate the cooling system thereby reducing its efficiency and causing damage to marine motors. Overheating problems usually result. Pitting corrosion occurs after salt has broken the alloy surface and it burrows into the actual motor block. Use of MACS Ultrafilm will help remove corrosion deposits and protect against further damage. However, MACS Ultrafilm does not repair existing corrosion.
