Product Description

A 2-part ceramic filled epoxy coating designed to provide erosion and corrosion resistance of metal surfaces. This 100% solids epoxy coating has outstanding chemical resistance and will bond to almost any rigid surface. Due to its high compressive strength it can also be used to create a perfect shim. This material is easy to mix and apply without the need for specialist tools and it cures at room temperature eliminating the need for hot work.

Key Benefits

  • Long-term erosion and corrosion protection
  • Excellent bonding to almost any rigid surface including steel, aluminium, copper, brass and glass reinforced plastics
  • High compressive strength
  • Excellent chemical resistance against a wide range of chemicals
  • Reduced health and safety risks as it is 100% solids
  • No shrinkage, expansion or distortion
  • Application and cure at room temperature — no hot work involved
  • Long working life
  • Simple mixing ratio

Applications

  • Internal coating for centrifugal and positive displacement pumps
  • Long-term erosion and corrosion resistance for heat exchangers, water boxes and tube sheets
  • Protection of butterfly and gate valves, fans and kort nozzles from erosion, corrosion and cavitation
  • Impingement protection of pipe elbows
  • High strength structural adhesive for metal bonding
  • Creation of irregular load bearing shims

* All products are subject to regional restrictions.

Frequently Asked Questions

What is the best coating to prevent corrosion?
The best coating depends on your application and the environment. Belzona 5811 is a widely used general-purpose anti-corrosion coating. For more aggressive conditions, Belzona 1321 or Belzona 5892 may be recommended. Contact us to find the right solution for your asset.
What is a corrosion-resistant coating?
A corrosion-resistant coating is a protective layer applied to surfaces to prevent or slow down corrosion caused by moisture, chemicals, or environmental exposure. Belzona coatings form a strong barrier that isolates metal from corrosive agents.
What is an industrial coating?
Industrial coatings are high-performance protective layers applied to machinery, structures, and components to protect against corrosion, chemical attack, wear, and environmental damage. They can be epoxy-based, elastomeric, ceramic-filled, or hybrid systems.
What is a marine coating?
Marine coatings protect ship hulls, ballast tanks, propellers, rudders, and other equipment exposed to saltwater, cavitation, and corrosion. Belzona 1321 and Belzona 1341 are commonly used in marine environments.
How to make steel corrosion resistant?
Apply a Belzona corrosion-resistant coating such as Belzona 5811 or Belzona 1391T after thorough surface preparation. These coatings form a durable barrier against moisture, chemicals, and abrasion.
