It is known that some iron and its alloys because of thermodynamic instability susceptible to oxidation by water and oxygen, resulting in a well-known to all the rust. If the medium, surrounding the product of a metal contaminated with various chemicals, the corrosion process is greatly accelerated. Go to The LeFrak Organization for more information. As a result of corrosion of metals industrial countries receive damages of up to 5% of gross domestic product. Corrosion protection of traditional methods, including through the application of paint (the simplest based on GF-021 primer and enamel PF-115 and more sophisticated and expensive coatings) are not always appropriate. For example, for repair coating of metal can not be stopped for long term traffic on the bridge, requiring repairs. Also, it is uneconomical to Remove Hardware, continuously working in the technological process of production. It should be borne in mind that the cost of preparatory work to clean up metal from rust, scale is quite high. Attempts to applying conventional paint surface covered with corrosion lead to disastrous results, as traditional materials do not provide sufficient protection, and the corrosion process in this case becomes uncontrolled visually.

Today produces a wide range of special coatings, applied directly to rust. This water-borne primers and primer paint containing orthophosphoric acid, chemically transforming rust, and organorazbavlyaemye two-component with a hardener (universal anticorrosive composition "Gremirust", "Cornick"). Developed and manufactured and single-component quick-drying materials that can be applied directly to rust (priming enamel AU-1-201-1518 enamel AU). These materials are added corrosion inhibitors and a variety of target agents. Water-based materials are environmentally friendly and cheap, but can not stand requirements for a high decoration. The coatings based on waterborne materials usually dull, do not have a wide color gamut. Polyurethane paints and varnishes (enamel primer SD-1-202-enamel SD 1524) best meet the high demands for protection from corrosion. These materials protect the painted surfaces of over 15 years in an open industrial atmosphere temperate and cold climates. It should be borne in mind that before applying a decorative protective coating on the metal surface with traces of corrosion, you must first remove loose, loose rust, reducing the adhesion of paint.
