[Case Study] Optimal for Preventing Sulfide in Electronic Circuit Boards

Fluorine-based conformal coating agent that prevents sulfide formation of Ag, Cu, and other metals from corrosive gases.

The "PCH Series" is a sulfurization prevention coating agent that protects metals such as Ag and Cu from corrosive gases. This product has a colorless and transparent film, so the total light transmittance does not decrease even after application. To evaluate gas corrosion resistance, we conducted a gas corrosion test to confirm the maintenance rate of gloss before and after testing. The results are detailed with comparative images of the silver plate used as the substrate, in its pre-test and uncoated state, and after applying this product. 【Features】 ■ Sulfurization resistance ■ Adhesion ■ Rust prevention ■ Transparency ■ Room temperature drying *Our products comply with the new 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.
