Overview of Belzona 1392
A two-component high temperature coating system specifically designed to provide erosion-corrosion protection in acid contaminated water and hydrocarbon systems. Belzona 1392 (Ceramic HT2) is resistant to water, aqueous solutions and hydrocarbons up to a temperature of 248°F (120°C) in continuous immersion.
This high-temperature coating exhibits excellent chemical resistance, particularly in systems contaminated by acid, and provides excellent erosion resistance. It also has excellent resistance to process chemicals and conditions such as steam-out and rapid depressurisation.
Key Benefits
Outstanding performance under elevated temperature conditions including dry heat and steam exposure
Excellent resistance to a wide range of chemicals including aqueous solutions, hydrocarbons, and process chemicals
Easy to mix and apply without specialist tools
100% solids formulation reduces health and safety risks in confined spaces with no shrinkage on cure
Exceptional compressive strength for load-bearing applications and demanding mechanical environments

Frequently Asked Questions
What is Belzona 1392 used for?
Belzona 1392 is a 2-part epoxy coating system providing high temperature corrosion protection for metal substrates. It is used on heat exchanger tube sheets, vessel internals, separators, and similar process equipment exposed to corrosive media at elevated temperatures.
What temperatures does Belzona 1392 handle?
Belzona 1392 is designed for high temperature service in both wet and dry conditions. Specific upper service temperature limits depend on the operating environment and the chemicals present — refer to the Product Specification Sheet and Chemical Resistance Chart for detailed data.
How is Belzona 1392 applied?
Belzona 1392 is brush-applied in two coats over an abrasive-blasted substrate. Application thickness, working life, and overcoat windows must be observed in accordance with the Instructions for Use to ensure proper film build and cure.
