Ultra-low surface tension for superior wetting and penetration in precision electronic cleaning applications.
Non-conductive and residue-free, ensuring no electrical shorting or post-process contamination on sensitive components.
Zero ozone depletion potential (ODP = 0) and very low global warming potential (GWP < 10), compliant with modern environmental regulations.
Thermally stable up to 200°C, enabling compatibility with high-temperature reflow and drying processes.
Chemically inert toward common PCB substrates, solder masks, conformal coatings, and elastomeric seals.
Final rinse and drying agent for aqueous-cleaned printed circuit board assemblies (PCBAs).
Flux residue removal from fine-pitch SMT components and 01005/008004 passive devices.
Carrier fluid for vapor phase degreasing systems using fluorinated solvent blends.
Coolant and dielectric fluid in immersion cooling solutions for high-power electronics and data center hardware.
Defluxing agent for aerospace-grade avionics where halogen-free, non-corrosive performance is mandatory.

Q1: What is the CAS Registry Number for KEY-117MAX?
A: The CAS number for KEY-117MAX Electronic Fluorinated Liquid is 2169575-82-1.
Q2: What is the recommended usage concentration when used as a rinse carrier?
A: KEY-117MAX is typically used neat (100% concentration); dilution is not recommended as it may compromise surface tension reduction and residue-free performance.
Q3: How does KEY-117MAX differ from traditional HFC-43-10mee or HCFC-141b alternatives?
A: Unlike legacy solvents, KEY-117MAX contains no chlorine or hydrogen atoms, eliminating ozone risk and offering superior chemical inertness and thermal stability—while maintaining comparable volatility and material compatibility.
Q4: Is KEY-117MAX subject to EU PFAS restriction proposals (REACH Annex XVII)?
A: No—KEY-117MAX is a defined, high-molecular-weight PFPE (MW > 1,000 g/mol) with no bioaccumulation potential and is explicitly excluded from current EU PFAS regulatory scope per ECHA’s 2023 guidance.
Q5: Has migration or leaching into silicone gaskets or polyimide films been observed during long-term storage testing?
A: Independent 6-month accelerated aging tests (85°C / 85% RH) showed no measurable migration, swelling, or extractables from KEY-117MAX into silicone elastomers (VMQ), polyimide films, or FR-4 laminates.
