Fundamental physics-chemical processes on the metal heat transfer surfaces determine the relationship between the processes of scale formation and corrosion. Application of polymer coatings on the inner surface of heat exchange tubes helps to reduce scale formation, reduce adhesion of deposits and prevent corrosion. Laboratory studies and a comprehensive survey

of the state of corrosion and scale formation have shown that the polymer coating ROCOR have proven themselves as an effective means of anti-corrosive protection and anti-scale action with the experience of industrial use of 12 years old.
