工業用溶剤

工業用溶剤は油分、グリース、樹脂、塗膜を溶解し、表面や配合物を工程が求める状態にします。 This family covers two working classes: oxygenated solvents, isopropyl alcohol (IPA, CAS 67-63-0) and n-butanol, and aromatic hydrocarbons, toluene and xylene. Oxygenated grades suit polar residues and general wipe-down cleaning; aromatics dissolve the heavy, nonpolar films that resist alcohols. Match solvent polarity to the soil you are removing rather than reaching for the strongest option by default.

Solvent power tracks with Kauri-butanol value and evaporation rate, and that is where the real trade-off lives. Toluene and xylene cut heavy coatings and adhesives that IPA cannot touch, but both are listed Hazardous Air Pollutants (HAPs) and volatile organic compounds (VOCs), so specifying them raises VOC reporting and ventilation obligations. Where a lighter soil allows it, an oxygenated solvent keeps VOC and HAP exposure lower. Confirm regulatory status for your application and jurisdiction.

IPA evaporates fast and leaves little residue, which makes it the default for precision wipe-down and electronics-adjacent cleaning; n-butanol evaporates slower and works as a coalescing co-solvent where flash-off needs control. For vapor degreasing and parts washing, specify by flash point and evaporation rate, not by name alone, because those two properties govern both throughput and fire-code handling on the line.
