SCRAP RATE REDUCTION SOLUTION - FLUOROSURF

1. What Is Fluoro Surf? The Ideal Alternative to Urethane and Silicone

Fluoro Surf is a specialized surface treatment chemical/coating solution developed by Fluoro Technology, Japan. This technology is based on dissolving special fluororesins in either non-flammable fluorine-based solvents or petroleum-based solvents.

After application by dipping or brush coating, the solvent evaporates extremely quickly, leaving behind an invisible ultra-thin nano-scale film. This film provides an exceptionally high contact angle — 117° with water and 76° with oil — creating an effective protective barrier against harmful external factors.

Compared with conventional urethane or silicone coatings, which are typically thick, slow-drying, and difficult to repair, Fluoro Surf offers a completely new standard of protection for industrial components.

2. Why Do Leading Factories Choose Fluoro Surf?

For production managers and QA/QC engineers, Fluoro Surf delivers three core advantages that directly improve production line efficiency:

Optimized Productivity and Shorter Takt Time

Unlike conventional coating solutions that require high-temperature drying ovens, Fluoro Surf dries rapidly at room temperature, just 5 seconds to 15 minutes. This allows factories to eliminate the drying process, reduce energy costs and CAPEX, and free up storage space for work-in-progress items waiting to dry.

High Safety and Environmental Compliance

Fluoro Surf’s non-flammable solvent series uses safe fluorine-based solvents that are non-ignitable, low-odor, and low-toxicity. In particular, the product is not classified as a hazardous organic solvent and is 100% free of PFOS/PFOA. This helps manufacturers meet strict audit requirements for occupational safety, fire prevention, RoHS, and REACH compliance.

Outstanding Physical, Mechanical, and Chemical Properties

With a film thickness of only 1 µm, treated components achieve a dielectric strength of up to 84 kV/mm, along with excellent moisture resistance, ion migration prevention, and resistance to electrolytic solutions.

3. Solving Key Challenges Across Industries

Fluoro Surf is not merely a chemical product. It is a tailored solution designed to address specific process and reliability issues across different industries.

Electronics Assembly and PCBA Industry
