PR402A is a highly concentrated, inhibited hydrochloric acid-based cleaner designed to rapidly remove water scale, rust, and concrete deposits. It includes a selected inhibitor system to protect most ferrous metals, copper, brass, and bronze, making it ideal for descaling boilers, heat exchangers, and associated plant, as well as cleaning construction equipment, tools, and scaffolding. Suitable for soak or circulation cleaning on ferrous metals with minimal corrosion on compatible materials; not recommended for galvanized steel, stainless steel, high-tensile steels (above 65 tons per square inch), soldered pipes, or aluminium.
Descaling boilers, heat exchangers, and steam cleaners.
Removing rust stains from building plant and equipment.
Eliminating concrete deposits from construction tools, scaffolding, and brickwork.
Boiler and Heat Exchanger Descaling: Perform a bucket test on a scale sample to confirm suitability (note: ineffective on pure silica). Use at 10% dilution in water for system treatment. For removable components, soak in a 1:2 ratio (PR402A to water), rinse thoroughly, and apply rust preventative if needed. Suitable for glass-lined boilers if not cracked; otherwise, use Inhibited Sulphamic Acid.
Steam Cleaner Descaling: Dilute to 10% in water and circulate cold per manufacturer's instructions.
Concrete Removal: For best results, immerse equipment in a 2:1 dilution (PR402A to water). Apply neat for direct use on plant equipment or to remove excess cement from brickwork. Always rinse thoroughly.
Handle as a concentrated acid; avoid mixing with bleach or hypochlorite-containing products.
Do not heat or apply to hot components; ensure adequate ventilation.
