Types of Anti-Corrosion Coatings for Steel Structure

2020-11-10

Anti-corrosion coating for steel structures is mainly divided into two categories: metal anti-corrosion coating and resistance to seawater corrosion coating.Anti-corrosion paint mainly includes: fluorocarbon top coat, acrylic polyurethane top coat, polyurethane paint, epoxy anti-corrosion paint, inorganic anti-corrosion coatings.

Metal anti-corrosion coating

  1. Main performance: excellent rust resistance and chemical corrosion resistance, abrasion resistance, freshwater resistance, seawater resistance, salt spray resistance, resistance to microbial erosion, electrical insulation, resistance to stray current, heat resistance, resistance to sudden temperature changes and other excellent performance.
  2. Range of application: used for the outer wall of buried pipelines, liquid storage tanks and floor, underwater and dry and wet environment of the steel structure and concrete.
  3. Features: The paint film has excellent rust resistance and chemical corrosion resistance, film toughness and wears resistance, resistance to freshwater, seawater, salt spray resistance; excellent resistance to microbial erosion, resistance to stray current, heat resistance, resistance to sudden changes in temperature and other excellent performance.
  4. Used: the anti-corrosion coating of the outer wall of buried pipelines, liquid storage tanks and floor, underwater and dry and wet environment of the steel structure and concrete.

 

Resistance to seawater corrosion coating

  1. Main performance: good abrasion resistance, impact resistance; excellent resistance to media permeability; excellent resistance to acid, alkali, salt, oilfield sewage, brine seawater and other chemical properties; good adhesion to the matrix, small coefficient of thermal expansion, good resistance to sudden changes in temperature.
  2. Scope of Application: The product is widely used for the anti-corrosion protection of most steel structures such as storage tanks, ships, bridges, offshore facilities, mining machinery, etc.
  3. Characteristics: Good abrasion resistance, impact resistance; excellent resistance to media permeability; excellent resistance to acid, alkali, salt, oilfield sewage, brine seawater and other chemical properties; good adhesion to the matrix, small coefficient of thermal expansion, good resistance to sudden changes in temperature.
  4. Used:industrial zones, chemical zones, coastal areas, bridges, chemical plants, power plants, shipyards, sea vessels, etc.

 

Benefits of choosing a good steel corrosion protection coating for your steel structure

  1. A good structural steel coating has good mechanical properties and excellent corrosion protection.
  2. It has good stability to climate, oil and water mixtures.
  3. It should be visually appealing and aesthetically pleasing in decoration.
  4. The anti-corrosion period is long because a large project cannot be carried out frequently for several years.
  5. Good paint can save an enterprise’s time and material resources, and play a non-negligible role in the development of enterprises.
