Applications are drawn from published manufacturer and supplier documentation; each is sourced. Suitability for a specific use is the buyer's to confirm.
Storage & Handling
- Recommended Storage
- Keep closed in plastic or stainless-steel containers, not mild steel. Protect from freezing; store away from bases and bleach.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
- Strong bases (heat); strong oxidizers and metal nitrates; bleach and other hypochlorites (release chlorine); reactive metals (release hydrogen). Slowly corrodes mild steel.Adjudicated
- Shelf Life
- Consult Technical Services for product-specific shelf life
For full hazard, PPE, and emergency response guidance, refer to the Safety Data Sheet (SDS) for this product. The SDS controls in all cases where guidance differs.
