Phosphoric Acid 85% Technical Grade

Phosphoric Acid 85% – Technical Grade

Phosphoric Acid (H₃PO₄) 85% is a high-purity, concentrated mineral acid widely used in metal treatment, cleaning, water conditioning, and chemical manufacturing. This clear, viscous liquid offers strong acidity with excellent chemical stability, making it ideal for applications requiring controlled reactivity and consistent performance. Its high concentration ensures efficiency in industrial processes, reducing chemical usage while delivering precise results.

Applications:

Metal Surface Treatment:
Used for cleaning, rust removal, and passivation of steel and other metals before painting, plating, or coating.

Industrial Cleaning:
Removes mineral deposits, scale, and oxidation from equipment, piping systems, and process vessels.

Water & Wastewater Treatment:
Controls pH levels in municipal and industrial water systems and aids in corrosion control.

Chemical Manufacturing:
Key raw material in producing phosphate compounds, detergents, and specialty chemicals.

Food & Beverage Equipment Maintenance (Non-Direct Contact):
Applied for descaling and sanitation of brewing, dairy, and beverage processing equipment.

Waste Treatment & Neutralization:
Used in industrial effluent treatment to adjust pH and precipitate heavy metals.

Safety Information:

Phosphoric acid is corrosive and should be handled in well-ventilated areas with appropriate PPE, including chemical-resistant gloves, splash goggles or face shield, acid-resistant clothing, and an acid vapor respirator when required. Store in HDPE, PTFE-lined, or other acid-compatible containers away from bases, reactive metals, and strong oxidizers. Maintain emergency eyewash and shower stations in all handling areas.

Overall:

Technical Grade Phosphoric Acid 85% offers high strength, consistent purity, and broad compatibility for industrial use. Its stability, concentration, and low contaminant profile make it a trusted choice for metal finishing, cleaning, water treatment, and chemical manufacturing operations where performance and reliability are critical.
