AIR. INDUSTRIAL ENVIRONMENT


Air is life.

 Even the purest air contains two major components that cause corrosion and decomposition. They are oxygen and water. Oxygen is an extremely powerful oxidizer. Water is a unique solvent capable of dissolving oxidation products as well as salts, acids and alkalis.

 How does then humankind manage to survive in this aggressive environment? What protects human beings throughout the 70 to 100 years of their lifetime?

 The optimal solution that nature has come up with is skin. Skin is a thin a mere half a millimeter layer of protein, i.e., an organic polymer. Skin is a kind of natural anticorrosion polymer coating with a complex multilayer (in other words, graded) structure, which explains its unique protective properties.

 But what we have to deal with is industrial environment. Apart from oxygen and water, industrial air contains numerous production-induced pollutants, such as carbon dioxide, sulfur oxides, particulate salts, fumes and aerosols of acids and alkalis, fumes of organic compounds. These pollutants are capable of facilitating oxidization and dissolution of corrosion products, destroying protective oxide films on metal surfaces and thus accelerating corrosion of all structural materials.

 Today these two words, industrial environment, warn of clear and present danger to metals and reinforced concrete structures, rails, bridges, aqueducts, gas purifying absorbers, high-speed fans, etc.

RECOMMENDED PROTECTION SCHEMES

 
For reinforced concrete

- Penetrating primer containing components that bind water and chemical pollutants (SELECTON-022, METACOR-02) + anticracking  coating (VICOR-755) + chemical-resistant coating (VICOR-7050, VICOR-593, VICOR-700)
 

For metals

- SELECTON-706 ground-coat enamel

- Prime coating containing protective, inhibiting and water-binding components (METACOR-01, METACOR-02, METACOR-03, METACOR-05, METACOR-07) + chemical-resistant coat (VICOR-700, VICOR-793, VICOR-7050, VICOR-7105)

 

METALWORK IN INDUSTRIAL ENVIRONMENTS

The  SELECTON compounds combine high weather resistance with chemical stability, thereby effectively protecting from corrosion the exposed surfaces of any metal structure or process equipment. The coatings we offer withstand spills of any aggressive liquids and exposure to aggressive aerosols and gases.

 

Metalwork in an industrial environment (bridges, sheds, conduits, tanks)

Metalwork in an industrial environment with stray current present (contact line masts)

SELECTON-706 ground-coat enamel          2 layers            400 g/m²

 

Metalwork in an industrial environment with stray current present (junction boxes, switch motors, chokes, transformers)

SELECTON-01 primer           1 layer               200 g/m²

SELECTON-793 enamel       1 layer              100 g/m²

SELECTON-7050 enamel     2 layers            200 g/m²

  

  

REINFORCED CONCRETE STRUCTURES IN CHEMICAL ENVIRONMENTS

 
We propose innovative solutions for the protection of reinforced concrete surfaces exposed to chemical action. They are based on selective immobilization of the contaminants implanted in the surface layer of the concrete structure, prevention of their recrystallization, and concrete hardening.

Reinforced concrete structures contaminated by chemicals

SELECTON-022 penetrating primer             1 layer             200-350 g/m²

SELECTON-722 enamel                                 2 layers            200 g/m²

 

Reinforced concrete structures with a degraded surface layer

SELECTON-022 penetrating primer             1 layer                350 g/m²

SELECTON-711 (elastic) enamel                 1 layer                100 g/m²

SELECTON-722 enamel                               2-4 layers        200-400 g/m²
