Formulation Notes
Electronic device cleaning requires a formulation that is non-conductive when dry and completely residue-free. A 70% isopropanol solution is the industry standard.
Formulation FC-10.7-P — Electronics-Safe Cleaner (Liquid)
Specification: pH 6.5 ± 0.5; surface resistivity > 1 × 10 Ω/sq (dry film, ASTM D257); residue after evaporation < 0.01 mg/cm². The 70:30 IPA:water ratio ensures rapid evaporation. The antistatic agent deposits a monolayer increasing surface conductivity to 10–10 Ω/sq, dissipating static charges without compromising ESD safety. The 0.2 μm filtration step removes particulates that could scratch displays or foul connectors.
