Product Description

A 2-part spray-applied epoxy coating designed to provide long-term corrosion and chemical resistance to equipment operating in continuous immersion at temperatures up to 140°C (284°F). This 100% solids coating has a long overcoat window and its cold curing mechanism with full in-service cure reduces downtime and ensures rapid return of equipment to service.

Belzona 1523 is easy to mix and apply using heated airless spray equipment, allowing large areas to be quickly and effectively protected.

Frequently Asked Questions

How do you apply a high temperature epoxy coating?

The application method depends on the product type and equipment geometry. Spray-applied systems like Belzona 1523 use heated airless spray equipment — ideal for large vessels, separators and production equipment requiring uniform film build over large surface areas. Hand-applied systems are chosen for complex geometries, nozzles and areas where spray access is restricted. For full information refer to the Instruction for Use (IFU).

Can Belzona 1523 be used for continuous hot immersion service?

Yes. Belzona 1523 offers outstanding corrosion protection for continuous immersion service in water and hydrocarbons at elevated temperatures, up to 140°C (284°F).

How long do high temperature epoxies take to cure?

Belzona 1523 cures at ambient temperature and post-curing is generally unnecessary as full cure is achieved in service. However, a controlled post-cure between 50°C (122°F) and 100°C (212°F) can be used to accelerate return to service where required.
