Product Overview
Alliance Chemical supplies Hydrochloric Acid 15% Technical Grade as a highly consistent aqueous solution of hydrogen chloride. This formulation, with the molecular formula ClH and a molecular weight of 36.46, acts as a versatile chemical intermediate and industrial acidifier. Characterized by its colorless, watery appearance and sharp, pungent odor, this 15% solution offers an optimal balance between concentration and ease of handling. It is commonly utilized across multiple sectors including metal cleaning, pH adjustment, and concrete etching, where controlled acidity is required.
Our technical grade hydrochloric acid is formulated specifically for industrial, commercial, and manufacturing processes that require a reliable acid source without the strict purity requirements of analytical reagents. With a CAS number of 7647-01-0, this product is manufactured to ensure uniform concentration throughout each batch. Alliance Chemical provides this chemical to support heavy industrial operations throughout Texas and nationwide, delivering consistent quality. We supply this product in multiple volume configurations, from quart bottles to bulk gallons, to suit your specific operational needs.
Why This Grade
Selecting the 15% Technical Grade concentration is critical for operations where higher concentrations, such as 31.45% or 37% muriatic acid, would be too aggressive or generate excessive fumes. This 15% concentration provides sufficient chemical activity for pickling, descaling, and neutralization while significantly reducing the rate of hazardous off-gassing and thermal reaction during dilution. The technical grade specification offers an economical threshold, allowing industrial facilities to scale their processes efficiently without paying the premium costs associated with ACS or electronic grade reagents.
Utilizing the incorrect concentration or grade in your process can lead to significant failure modes. For example, using a concentration higher than 15% in masonry etching can damage the underlying concrete structure by reacting too rapidly, resulting in uneven surfaces. Conversely, selecting a lower grade with uncontrolled impurities could introduce heavy metal contaminants into wastewater treatment systems, leading to compliance failures and system corrosion. This 15% Technical Grade balance ensures predictable reaction rates and protects process equipment from premature degradation.

Industrial Applications
- Metal Pickling and Cleaning: Used to remove rust, scale, and iron oxide coatings from steel and iron parts before further surface treatment in metal finishing shops.
- Industrial pH Adjustment: Serves as an effective acidifier to neutralize alkaline wastewater streams in manufacturing plants and municipal treatment facilities prior to discharge.
- Concrete and Masonry Etching: Applied to concrete surfaces to open the pores and prepare the substrate for industrial coatings, sealers, and paints.
- Boiler and Heat Exchanger Descaling: Formulated into cleaning solutions to dissolve calcium carbonate and mineral scale deposits from the interiors of industrial heat transfer equipment.
- Regeneration of Ion Exchange Resins: Employed to regenerate cation exchange resins used in industrial water demineralization systems, restoring the active hydrogen ions.
Hazmat & Shipping
Hydrochloric Acid 15% Technical Grade is classified as a regulated hazardous material for transport. It must be shipped under the proper shipping name Hydrochloric acid, designated as UN1789, Hazard Class 8, and Packing Group II. The authoritative signal word for this chemical is Danger. Because of its corrosive nature and toxicity risk, shipments must comply with strict DOT guidelines. We package and ship this material in approved, heavy-duty containers designed to withstand corrosive substances during transport, ensuring safe transit to your facility.
Due to the hazard classifications H314 (Causes severe skin burns and eye damage) and H331 (Toxic if inhaled), personnel must wear appropriate personal protective equipment (PPE) when handling this product. This includes acid-resistant gloves, chemical splash goggles, a full-face shield, and protective clothing. If working in areas with limited ventilation where vapors may accumulate, an approved respirator equipped with acid gas cartridges is necessary to prevent inhalation. Consult the Safety Data Sheet (SDS) provided with every order for complete regulatory compliance and handling protocols.
Handling & Storage
Proper storage of Hydrochloric Acid 15% Technical Grade requires maintaining it within a moderate temperature range, ideally between 50°F and 85°F, away from direct sunlight and sources of heat. The solution must be stored in compatible, corrosion-resistant containers such as high-density polyethylene (HDPE), polypropylene, or glass. Do not store this chemical in carbon steel, aluminum, or other reactive metal containers, as it will rapidly react to release flammable hydrogen gas. Keep containers tightly closed when not in use, and store away from incompatible substances including strong bases, oxidizing agents, and active metals.
