Sulfurization prevention coating agent protects the substrate from corrosive gases!
PCH
The ideal coating agent for preventing sulfide! It prevents substrate corrosion with a fluororesin film that has gas barrier properties.
The "PCH Series" is a sulfurization prevention coating agent that protects metals like 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 total light transmittance does not decrease even after application. To evaluate gas corrosion resistance, we conducted gas corrosion tests 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, uncoated state, and after applying this product. 【Features】 ■ Sulfurization resistance ■ Corrosive gas resistance ■ Moisture and drip protection ■ Adhesion ■ Rust prevention ■ Transparency ■ Room temperature drying
