- Handling Precautions
- Use full PPE including face shield, acid-resistant gloves and apron. Add acid to water slowly with stirring; never reverse. Ventilation required.Class-level guidance — not product-specific; the SDS controls.
- Incompatibilities
- Strong oxidizers (chromic, nitric and perchloric acids, peroxides, permanganates); bases and caustics; ammonium nitrate; acetaldehyde; most common metals (corrosion, hydrogen). Attacks many plastics, rubbers and coatings.Adjudicated
- Shelf Life
- Consult Technical Services for product-specific shelf life
