- RoHS Compliant
Prices were revised effective May 1, 2026.
This moisture-proof and anti-corrosion coating agent offers excellent gas barrier properties and is effective against moisture and corrosive gases. It provides superior insulation, enhancing the insulation reliability of narrow patterns on printed circuit boards. It protects circuit boards from corrosive gas atmospheres, such as those found in hot spring areas, and from salt damage in coastal regions.This product is not subject to the Organic Solvent Poisoning Prevention Regulations. As it is classified as Class 2 petroleum products, regulations on usage and storage quantities are less stringent than those for Class 1 petroleum products. There are two variations based on volume and six variations based on color. View variations by volume View variations by color
