Applications
Cleaning and descaling concentrate; pH adjustment; industrial use.Adjudicated
Restrictions on Use: Technical grade: not for food or beverage use. Dilute before use; do not use undiluted on surfaces that acids damage. Never mix with bleach.
Storage & Handling
- Recommended Storage
- Store sealed in the original corrosion-resistant container (polyethylene, glass or stainless steel; not mild steel or aluminum) in a cool, dry, well-ventilated area out of direct sunlight, away from oxidizers, bases and foodstuffs. Protect from freezing.Adjudicated
- Handling Precautions
- Use standard chemical PPE — splash goggles, gloves, lab coat. Refer to SDS for hazard-specific PPE requirements.Class-level guidance — not product-specific; the SDS controls.
- Incompatibilities
- Oxidizing agents (peroxides, permanganates, nitric and chromic acid); bleach and other hypochlorites (release chlorine); hydroxides and other bases; soluble carbonates and phosphates; metals (releases hydrogen); amines; alcohols.Adjudicated
- Shelf Life
- Consult Technical Services for product-specific shelf life
