Application Guidance
Isopropyl Alcohol 91%- USP Grade (USP Grade) is a polar solvent. Grade selection (technical, ACS, electronics, USP) determines acceptable residue and impurity levels for the intended end-use.
- Cleaning and degreasing (technical-grade)
- Coatings, inks, and adhesives formulation
- Reaction solvent for chemical synthesis
- Pharmaceutical manufacturing (USP-grade)
- Electronics-grade cleaning and rinse applications
Flammable. Bond and ground equipment during transfer. Verify grade matches end-use specification before substitution.
Storage & Handling
- Recommended Storage
- Cool, well-ventilated flammable-liquid storage area. Tightly sealed original containers. Segregate from oxidizers and acids. Bond and ground bulk storage.
- Handling Precautions
- Use chemical-resistant gloves and splash goggles. Bond and ground during transfer to prevent static accumulation. Eliminate ignition sources within vapor envelope.
- Incompatibilities
- Strong oxidizers, strong acids, isocyanates, anhydrides. Hygroscopic — protect from atmospheric moisture for water-sensitive end uses.
- Shelf Life
- 24 months from date of manufacture in sealed, original packaging
