The ideal coating agent for preventing sulfurization of LEDs! It is a transparent fluororesin film with gas barrier properties that prevents brightness reduction due to sulfurization of silver plating.
The "PCH Series" is a sulfurization prevention coating agent that protects metals such as Ag and Cu from corrosive gases. It not only prevents sulfurization but also protects against moisture, making it ideal for LED mounting substrates. Since this product forms a colorless and transparent film, the overall light transmittance does not decrease even after application. To evaluate gas corrosion resistance, we conducted gas corrosion tests to confirm the maintenance rate of glossiness before and after testing. The results are detailed with comparative images showing the silver plate used as the substrate in its pre-test, uncoated state, and after applying this product. 【Features】 ■ Sulfurization resistance ■ Adhesion ■ Rust prevention ■ Transparency ■ Room temperature drying *Our products comply with the REACH PFOA regulations and can be used without any issues. Please feel free to contact us, as we have 10 years of experience and achievements in PFOA countermeasures.
