Application Guidance
60/40 Methanol/DI Water Solution ACS Grade (ACS 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
- Keep containers tightly closed in a cool, dry, well-ventilated flammables area away from heat, sparks, open flame and direct sunlight. Store locked up. Ground and bond containers when transferring.Adjudicated
- Handling Precautions
- Use chemical-resistant gloves and splash goggles. Bond and ground during transfer to prevent static accumulation. Eliminate ignition sources within vapor envelope.Class-level guidance — not product-specific; the SDS controls.
- Incompatibilities
- Strong oxidizing agents and peroxides; strong acids, acid anhydrides and acid chlorides; strong bases; alkali metals; aluminum, zinc and lead (corroded, especially by dry methanol).Adjudicated
- Shelf Life
- Consult Technical Services for product-specific shelf life
