Nanoskin 99.9 % Isopropyl Alcohol is a technical-grade solvent refined to laboratory standards; every batch is tested to confirm less than 0.1 % water, so professionals can count on a rapid, even evaporation and a surface that dries absolutely residue-free. This level of purity is critical when a trace of moisture or contaminant can distort a laser beam, undermine instrument calibration, or weaken an adhesive bond. In electronics assembly and repair it lifts flux, fingerprints and skin oils from printed-circuit boards, connectors and sensors, flashing off in seconds to leave components spotless and ready for conformal coating or immediate re-use. Optics technicians rely on the same fast-drying action to clear dust and smudges from lenses and mirrors without streaks or haze, while additive-manufacturing operators use it as a primary wash for uncured SLA resin and as a build-plate prep that promotes reliable first-layer adhesion. In laboratories and production lines the solvent's strong affinity for hydrocarbons lets it dissolve greases, uncured polymers, inks and light oils on contact, streamlining QC protocols, paint-prep, and auto-detailing wipe-downs of chrome, stainless and glass. Because the product contains no added water or fillers it also performs in countless niche roles—thinning specialty coatings, removing sticker residue, cleansing tools between batches of epoxy, or acting as the water-free carrier in custom formulations where consistency matters more than cost. Whatever the task, users gain the same predictable flash point, consistent evaporation rate and clean, dry finish. For external use only. This is a flammable liquid: work in a well-ventilated area, keep away from ignition sources, and reseal the container promptly after each use.
