FC 106 is a high-performance fluorosurfactant designed to deliver extremely low surface tension, enabling excellent wetting on difficult-to-coat substrates commonly used in advanced electronics.
In electronic applications, FC 106 helps achieve uniform, defect-free films in conformal coatings, soldering pastes, potting compounds, and sealants used on PCBs, connectors, sensors, and other fine components. Its modern fluorosurfactant chemistry provides an excellent balance of wetting power, bath stability, and low foaming, while maintaining outstanding performance even at very low dosages. By improving flow and levelling without significantly impacting viscosity or other bulk properties of the formulation, FC 106 gives formulators a powerful tool to fine-tune surface behaviour. It is compatible with many resin systems typically used in electronics, including UV-curable, epoxy, acrylic, and urethane systems, and enhances penetration into tight gaps and microstructures, improving coverage in densely packed electronic assemblies and filled potting systems. By reducing pinholes, craters, edge crawling, and voids in soldering pastes and sealants, FC 106 supports higher reliability and long-term protection of sensitive electronic devices, making it a specialty additive of choice for next-generation electronic materials where precision, reliability, and low defect levels are critical.

Viscous liquid
Delivers ultra-low surface tension for complete coverage on complex PCB topography, minimizing pinholes, craters, edge-crawling, and other coating defects.
Improves wetting of pads and fine-pitch components, promoting uniform solder spread, fewer voids, and more reliable joints in surface-mount and micro-electronics.
Enhances penetration into tight gaps and under components, reducing trapped air, improving void-free encapsulation, and protecting devices from moisture and contaminants.
Provides excellent flow and wetting along narrow gaps and interfaces, enabling consistent sealing performance and long-term environmental resistance.
Optimizes flow, levelling, and substrate wetting in UV-curable, epoxy, acrylic, and urethane systems used on connectors, sensors, displays, and other high-value electronic parts.

100% active C6 fluorosurfactant – delivers strong wetting and levelling with minimal addition, keeping cost and formulation change low.
Fluorinated structure maintains wetting and flow under thermal cure, reflow, and chemical stress typical of electronic manufacturing.
Non-ionic nature works well in UV, epoxy, acrylic, urethane and silicone systems without significantly affecting viscosity or electrical properties.
Treat as an industrial specialty chemical. Avoid breathing vapours/mist and avoid direct contact with skin and eyes. Use only in well-ventilated areas or with local exhaust.
Wear safety goggles or face shield, chemical-resistant gloves (e.g. nitrile), and suitable protective clothing. In spray or high-temperature operations, use appropriate respiratory protection as per plant HSE rules.
Skin contact: Wash immediately with plenty of soap and water; remove contaminated clothing.
Eye contact: Rinse cautiously with water for several minutes; seek medical attention if irritation persists.
Inhalation: Move person to fresh air and keep at rest; get medical advice if symptoms occur.
Ingestion: Rinse mouth, do not induce vomiting; seek medical attention.
Product has a flash point above 58 °C but may release irritating or toxic fumes if overheated or burnt; use foam, dry chemical or CO₂ extinguishers and wear self-contained breathing apparatus in a fire situation.
Fluorinated materials are persistent; prevent spills from entering drains, soil, or natural water bodies. Collect spills with inert absorbent and dispose of waste and empty containers according to local regulations and the official SURFLON S-386 SDS.
