In many cases, the deposited aluminum can be left unprotected, without the use of impregnation. The use of aluminum alloy with 5% magnesium is a great alternative to coating with paint. This alloy is an effective coating for offshore platforms and components that are on deck. Thermally sprayed aluminum is well used for factory equipment operating at high temperatures. When using epoxy impregnation, the coating can withstand up to 5000S, using silicone impregnation – a higher temperature.

In contrast to the coverage surface of the paint coated products Spramet can be used almost immediately after application. Still less damage during operation will be, if coat the individual parts in the production process that allows the sprayed coating to any part of the product and makes it possible to assemble the product after completion or after the repair. The study of the corrosion process by the American Welding Society for 19 years in 1974, the American Welding Society has completed the 19-year study of corrosion protection, zinc and aluminum sputtering coatings on steel with low carbon content. The results of this study the following: aluminum coating thickness of 0.08-0.15 mm, as with the use of impregnation, and without it, provide complete corrosion protection of the base metal for 19 years in sea water and in harsh marine and industrial atmosphere; Zinc coverage without the use of impregnation should be 0.30 mm thick in order to ensure full protection of the surface in sea water for 19 years. In a tough marine and industrial atmosphere, zinc coating thickness of 0.23 mm without of impregnation and 0.08-0 .. 15 mm using impregnation, provide corrosion protection for 19 years in the harsh conditions of the marine atmosphere exposure, apply a layer of wash solution and add 1-2 layers vinyl aluminum. This will improve the appearance of the product and prolong the life of the zinc coating is nearly 100%.
