Key Features & Advantages

  • ✅ Chemically Inert – Fully fluorinated C–F backbone resists acids, bases, oxidizers, and solvents

  • ✅ Non-Flammable – No flash point, safe for sensitive environments

  • ✅ Low Toxicity – LD50 >5000 mg/kg (oral), non-carcinogenic

  • ✅ Fast Drying – High vapor pressure leaves no residue after evaporation

  • ✅ Low Surface Tension – Excellent wetting and penetration for cleaning

  • ✅ Thermally Stable – Use up to ~250°C safely (avoid >300°C decomposition)

Applications

  • Precision electronics cleaning (PCBs, connectors, sensors)

  • Heat transfer fluid / coolant for semiconductor and power electronics

  • Vapor phase reflow soldering (inert atmosphere)

  • R&D and specialty fluorinated solvent applications

  • Fire extinguishing agent formulations

  • Medical device cleaning (on request for higher purity grades)
