Hydrochloric Acid 15% Technical Grade

Product Overview

Hydrochloric Acid 15% Technical Grade is a clear, colorless to slightly yellow aqueous solution of hydrogen chloride (HCl). Often referred to as Muriatic Acid or Spirits of Salt, this concentration provides powerful acidic performance for industrial applications requiring precise pH control and aggressive reactivity. The 15% concentration is optimized for ease of handling while maintaining sufficient strength for metal pickling, scale removal, and neutralization processes.

This Technical Grade solution is manufactured to meet strict specifications for industrial use. It is widely employed in water treatment facilities for alkalinity control, in metal processing for surface preparation, and in the chemical industry as a fundamental reagent. The product minimizes trace impurities to prevent contamination in downstream operations, offering a reliable acid source for manufacturing and processing environments.

Safety Precautions

Hydrochloric Acid 15% is corrosive and must be handled with strict safety protocols. It causes severe skin burns and eye damage and may cause respiratory irritation. Store in corrosion-resistant containers (HDPE or rubber-lined steel) in a cool, well-ventilated area, separated from oxidizing agents and strong bases.

PPE Requirements: Wear chemical-resistant gloves, splash goggles, face shield, and protective acid-resistant clothing. Ensure safety showers and eye wash stations are accessible. In case of spills, neutralize with soda ash or lime before disposal in accordance with local regulations.

Shipping Information: UN 1789, Hydrochloric Acid, Class 8, PG II. Hazardous material shipping regulations apply.
