AQUACOAT "CONW-54"
AQUACOAT "CONW-54" is VOC free moisture proof coating material for PCB. It is veryenvironmentally-friendly because it contains water as solvent instead of organic solvent, and also keep have high property such as low coefficient of elasticity, heat resistance, high insulation property.
