Fluorinert Liquid FC-GK160 FC-40 Substitute

Fluorinert Liquid FC-GK160 – High-Performance Perfluorinated Coolant (3M FC‑40 Substitute)

Overview
Fluorinert Liquid FC‑GK160 is a colorless, odorless, non‑toxic perfluorinated fluid developed and manufactured in China as the first high‑boiling fluorinated fluid. It serves as a direct substitute for 3M™ Fluorinert™ FC‑40, offering equivalent performance with excellent dielectric properties, chemical inertness, thermal conductivity, very low surface tension, and low kinematic viscosity. Its compatibility with various system materials makes it ideal for demanding heat transfer and electronic testing applications.

Key Properties

• High dielectric strength – non‑conductive, safe for live electronics.

• Excellent thermal stability – maintains performance over a wide temperature range.

• Very low surface tension and viscosity – enables efficient wetting and flow in tight spaces.

• Chemically inert – compatible with most metals, plastics, and elastomers.

• High boiling point – suitable for single‑phase liquid cooling.

• Non‑flammable, no flash point – eliminates fire risk.

Environmental & Safety Profile

• Ozone Depletion Potential (ODP) = 0

• Low Global Warming Potential (GWP)

• VOC‑free (Volatile Organic Compounds)

• RoHS 2.0 compliant

• Non‑toxic under normal use; TWA (Time‑Weighted Average) is high, indicating low hazard.

• None of the ingredients are listed as carcinogens by OSHA, IARC, or NTP.

Applications

1. Semiconductor manufacturing: Used in packaging, testing, and thermal shock testing of electronic components.

2. Electronics cooling: Single‑phase heat transfer fluid for computer servers, power electronics, and high‑performance computing systems.

3. Thermal shock testing: Provides rapid and uniform temperature change without risk of electrical shorting.

4. Solvent applications: Acts as a diluent for lubricants and other specialty solvents.

Compatibility

• Excellent compatibility with most construction materials (metals, plastics, elastomers).

• Avoid mixing with strong acids, strong bases, and reducing agents.

• Compatibility testing is recommended before full‑scale use.

Handling and Storage

• Transported as non‑hazardous, non‑corrosive chemical.

• Store at room temperature in tightly sealed containers, away from direct sunlight and high temperatures.

• Ensure proper ventilation when handling.

Packaging
Available in various container sizes (e.g., 1 L, 5 L, 20 L drums) and custom packaging upon request.

Quality Assurance
Each batch is tested for purity, dielectric strength, and physical properties to ensure consistent performance.
