Q1: What is the CAS Registry Number for KEY-118?
A: The CAS number for KEY-118 Electronic Fluorinated Liquid is 13252-13-6 (representative PFPE structural analog; exact proprietary composition is protected under trade secret provisions).
Q2: What is the recommended usage concentration when used as a carrier solvent?
A: KEY-118 is designed for neat (100%) use — no dilution required. It functions effectively as a pure-phase solvent in vapor degreasing, immersion, and spray applications.
Q3: How does KEY-118 compare to traditional chlorinated or hydrocarbon solvents?
A: Unlike chlorinated solvents, KEY-118 contains no chlorine or bromine and poses no carcinogenic or ozone-depleting risk. Versus hydrocarbons, it offers superior dielectric safety, non-flammability, and zero residue — eliminating post-clean drying steps.
Q4: Is KEY-118 subject to migration or leaching into sensitive polymer substrates?
A: Extensive compatibility testing shows negligible absorption or extraction in PET, PTFE, polyimide, and silicone elastomers after 72-hour exposure at 25 °C. No swelling, clouding, or dimensional change observed.
Q5: Does KEY-118 require special regulatory certification for export to the EU or Japan?
A: KEY-118 is pre-registered under REACH and fully compliant with Japan’s Chemical Substances Control Law (CSCL). Full SDS, TSCA Inventory status, and PFAS reporting documentation are available upon request.
