Apexior 1

Hot water side boiler coating 370°C. Apexior 1 is a single component, solvent-based, air-drying organic type coating. It is easy to apply and is specifically formulated for the hot water-side corrosion prevention of metal surfaces.

Intended Uses

Apexior 1 is a coating that excels in severe thermal cyclic immersion service and is resistant to continuous immersion in boiling water and steam from 100°C to 370°C.

It aids in the reduction and prevention of tight bonding of hard scale and allows for easy cleaning and removal of any scale build up in steam generating equipment.

Apexior 1 prevents pitting corrosion and stops corrosion that has already begun - except for badly pitted areas. It has outstanding wetting properties and adheres well to power tooled cleaned areas.

Equipment coated with Apexior 1 will also see an increase in heat transfer efficiency. Apexior 1 performs ideally with water treatment in steam generating equipment.
