About the product
Resonac’s silicone-free insulation coating materials protect the connections of display peripheral circuits and prevent electrode corrosion caused by moisture absorption, thereby contributing to higher device reliability.
Merits
Protects circuits from moisture with low moisture permeability.
Low ionic impurities and high insulation reliability.
Inhibits electrode corrosion even under high-temperature, high-humidity conditions.
Excellent workability with short curing time and repairability.
Selectable solvent volatilizing and UV curing types based on applications and curing processes.
