Belzona 5811 Immersion Grade Epoxy coating

Belzona 5811 (Immersion Grade)

A 2-part epoxy coating which provides outstanding chemical resistance and protects equipment operating under immersion in aqueous solutions up to 50°C (122°F) from the effects of corrosion. This 100% solids material can be easily applied by brush or spray to virtually any metallic and non-metallic surface, simplifying maintenance works.

Key benefits:

Effective protection of equipment operating under immersion conditions from corrosion damage
Reduced health and safety risks as it is 100% solids
Easy application by brush or spray and cure at room temperature - no hot work involved
Excellent chemical resistance against a wide range of chemicals as well as sea water and crude oil
Eliminates the need for replacement and reduces downtime

Do coatings prevent corrosion?

An epoxy coating can prevent corrosion. Belzona recommends anti-corrosion coatings such as Belzona 5811 (Immersion Grade) as they will protect the substrate against deterioration or corrosion from chemicals, oxidation, moisture, and a variety of environmental factors.

What is an immersion coating?

An immersion coating is a protective layer applied to surfaces exposed to continuous contact with liquids, such as water, oil, or chemicals. These coatings are designed to resist chemical attack, erosion, and corrosion over time in fully submerged conditions. Belzona 5811 (Immersion Grade) is an example of a two-part epoxy immersion coating that offers long-term protection for metal and concrete surfaces in harsh environments.

How do you protect equipment from corrosion under immersion?

To protect equipment from corrosion in immersion conditions, Belzona 5811 (Immersion Grade) is often used as it provides excellent long-term protection by isolating the substrate from corrosive agents, making it ideal for tanks, pipework, and structural steelwork in contact with liquids.

Do you have Belzona products for potable water applications?

Yes. Belzona offers WRAS-approved coatings like Belzona 5811DW2 for contact with potable (drinking) water. These products meet stringent health and safety standards.

Do you provide pipeline coatings?

Yes. Belzona provides internal and external pipeline coatings that resist corrosion, erosion, and chemical exposure. Belzona 5811 (Immersion Grade) is often used for pipe protection and rehabilitation.
