How to distinguish between water-based anti-corrosion paint and water-based anti-rust paint

From the name, we can know that the difference between the two is mainly to prevent corrosion and prevent rust. Both have different roles and have different advantages. Now all countries are actively responding to the oil-to-water policy, allowing water-based industrial coatings to have more room for development, and water-based industrial coatings will also be an inevitable development trend in the coatings market.

Water-based anti-corrosion paint VS water-based anti-rust paint:

1. The main function of anti-rust paint is to protect the metal surface from corrosion by the atmosphere and sea water. It can be divided into two categories: physical anti-rust paint and chemical anti-rust paint. The former relies on the proper use of pigments and paints to form a dense paint film to prevent the intrusion of corrosive substances, such as iron red, aluminum powder, graphite anti-rust paint, etc.; The latter relies on the chemical rust inhibition of anti-rust pigments, such as Hongdan, Zinc yellow antirust paint, etc. It is used for rust prevention of metals such as bridges, ships and pipes.

2. The anti-rust pigment of the anti-rust paint is an important factor to prevent the product from rusting. The physical anti-rust pigment is a kind of pigment with relatively good chemical stability. It also depends on its own chemical properties, physical properties, hard texture and fine particles, excellent filling, improve the density of the paint film, reduce the permeability of the paint film and play a role in rust prevention. Iron oxide red is such a substance. The rust resistance of metal aluminum powder is due to the scaly structure of aluminum powder, which forms a tight paint film and has a strong ability to reflect ultraviolet light, which can improve the anti-aging ability of the paint film.

3. The anti-corrosion paint commonly used in the industrial industry is a relatively common kind of paint, which is used for the surface of the object to not corrode. Anti-corrosion paint is widely used, mainly used in aviation, shipbuilding, chemical industry, oil pipeline, steel structure, bridge, oil brick well platform and other fields. The paint can be used in harsh conditions and has good durability and weather resistance. It can be used for 10 years or more than 15 years in harsh conditions such as ocean and underground, even in acid, alkali, salt and solvent media. And under certain temperature conditions, it can also be used for more than 5 years.

4. The anti-corrosion paint cannot be used with rust when in use. The metal surface should be cleaned first, and then painted on the metal surface.

Through the above introduction and comparison, you should have a better understanding of water-based anti-corrosion paint and water-based anti-rust paint, and you can make more targeted choices when choosing products in the future.
