Definition - What does Corrosion-Resistant Coating mean?
Corrosion-resistant coating is applied on metal parts for the purpose of preventing corrosion. This type of coating can be made from substances such as zinc or iron and can be applied as a base layer, primer or topcoat through various techniques. It is commonly used to give corrosion protection to structures like pipelines and concrete bars.
Corrosionpedia explains Corrosion-Resistant Coating
Corrosion-resistant coatings can be modified to offer corrosion protection for various substrates and corrosive environments. For instance, chromium and cobalt alloys provide excellent resistance to corrosion. This type of coating can be applied to under 1% porosity levels in order to stop or deter corrosive attacks.
Corrosion-resistant coatings can help prevent degradation brought on by oxidation, moisture, exposure to chemicals and more. They provide extra protection to metal parts and function as a barrier to prevent contact between corrosive materials and chemical compounds.
Some benefits of using corrosion-resistant coatings include:
- Corrosion protection - Metal components are protected against erosion, heat and corrosion.
- Less friction - These coatings promote mill scale, corrosion byproduct and calcification removal. They can also aid in the prevention of adhesions.
- Surface preparation - This can also serve as a highly reliable coating for surface preparation, which enables further painting or coating. It also facilitates excellent electric isolation and adhesion.
Corrosion-resistant coatings' properties include:
- Minimal surface preparation required
- Requires no primer coat
- Dries easily and allows high build though a single coat
- Meets environmental and state guidelines without compromising quality
- Safe and decreases workers' exposure to toxins
