Belzona 1523

The application method for a high temperature epoxy coating depends on the product type and the geometry of the equipment being protected. Spray-applied systems such as Belzona 1523 are typically applied using airless spray equipment. This method is ideal for large vessels, separators and production equipment where a uniform film build and efficient coverage are required. Spray application allows controlled thickness over large surface areas and is well suited to shutdown projects with tight timelines.

Hand-applied systems such as Belzona 1593 are applied using brush or applicator tools. These are often chosen for complex geometries, detailed areas, nozzles and repairs where spray access may be restricted. Hand application also provides excellent control in confined spaces or when working around internal components. For full application information please check the information for us sheet (IFU).

Yes, spray applied high temperature epoxy coatings are suitable for continuous immersion service in water and hydrocarbons at elevated temperatures. Belzona 1523 offers outstanding corrosion protection up to 140°C (284°F).

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