Plan a trial for your application
Industrial cleaning
Wipe the actual substrate. Inspect for streaks and residue after evaporation.
Co-solvents in waterborne inks
Compare formulation clarity, viscosity and drying time on press.
Purchase specifications and incoming inspection
Review these properties when selecting and inspecting incoming material. Example figures refer to the cited grade or source. Confirm the offered specification, packaging and lead time in the quotation. Shell · Isopropyl alcohol technical data ↗
| Property | Unit | Published or agreed specification | Test conditions and checks |
|---|---|---|---|
| Purity | % by mass | Agree for the grade and end use | Request the GC method and impurity list. |
| Moisture | % by mass | Agree for the grade and end use | Report moisture separately. Chromatographic area percentage does not establish purity on a water-inclusive basis. |
| Nonvolatile matter | mg/kg | Agree for the grade and end use | Agree the residue limit for the target substrate. |
When approving a sample, record the grade, methods, limits and specification revision. On receipt, match the packing lot number to the lot-specific COA and record the measured values and release decision.
From samples to commercial delivery
Packaging and receiving
State anhydrous or water-containing grade, net drum weight and seal in the enquiry.
Storage and handling
Verify fire precautions, transport documents and receiving conditions against the SDS.
Sample and order lead times
State receiving tank capacity or required drum size, trial quantity and destination. Ask for sample carriage, commercial MOQ, packaging charge, availability and expected warehouse delivery date.
Questions from the plant
Why are water marks left after cleaning?
Compare solvent moisture, non-volatile matter, wipe material and a substrate blank.
Can industrial-grade IPA be used for high-cleanliness work?
Review impurity and particle limits first. Test residue on the actual substrate.
Report a delivery or batch issue
Include the order number, lot number from the package, label photos and inspection records for the affected lot. When retesting, check Purity, Moisture, Nonvolatile matter.
