Hayacoat Mark2 EF (undiluted type / red / 1kg) (AY-L1003R)

Insulation coating for substrates with excellent moisture-resistant and corrosion-resistant gas

• Aerosol and Chemical Products
• Conformal Coating for Moisture-resistant and Anti-corrosive
• RoHS compatible

Prices have been revised from August 1st, 2025.

This is a moisture-proof and rust-proof coating that has excellent gas barrier properties and is effective against moisture and corrosive gases. It has excellent insulation properties and improves insulation reliability for narrow patterns on printed circuit boards. Protects the substrate from salt damage in corrosive gas atmospheres such as hot springs, and in coastal areas. It does not fall under the Organic Solvent Poisoning Prevention Rules. There are 2 variations with different content and 6 variations with different colors.See variations of different contentSee different colour variations
