Phosphoric Acid 85% is a versatile inorganic acid used in metal finishing for pickling, derusting, and phosphate conversion coatings, as well as in numerous process formulations.
Material sourced from Vietnam and Taiwan is available in both Technical and Food grades, enabling applications from heavy‑duty metal treatment to more sensitive operations. Its controlled concentration and low impurity profile support reliable surface preparation, improved coating adhesion, and long‑term corrosion resistance on steel and other metals.
| Sr. No. | Description | Specification |
|---|---|---|
| 1 | Purity | 85% w/w Phosphoric Acid (Technical and Food grade options) |
| 2 | Chemical Formula | H3PO4 |
| 3 | Form | Clear, colourless to slightly hazy viscous liquid |
| 4 | Country of origin | Vietnam, Taiwan |
| 5 | Quantities | Available in standard industrial 35 litre carba |
Medium‑strength, triprotic acid with high affinity for metal oxides
Miscible with water; exothermic on dilution
Non‑volatile, stable under normal storage conditions
Corrosive to many metals; compatible with certain stainless steels and plastics
Steel pickling and derusting prior to painting or plating
Phosphate conversion coatings as part of multi‑stage pretreatment lines
pH adjustment and buffering in various metal‑treatment formulations
Food-grade suitable for approved applications where specified
Corrosive liquid; requires acid‑resistant pumps, piping, and storage tanks
Add acid to water during dilution, never the reverse
Use appropriate PPE including gloves, goggles, and aprons; ensure eye‑wash and safety showers are available
Follow local regulations for storage, bunding, and effluent discharge
