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.
