Insulating Coating Agent for Substrates with Excellent Resistance to Moisture and Corrosive Gases

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.Not subject to the Organic Solvent Poisoning Prevention Regulations. Available in two variations by volume and six variations by color. View variations by volume View variations by color
