- RoHS Compliant
Prices were revised effective July 1, 2023.
This UV-curable insulating coating offers excellent resistance to moisture and corrosive gases. It contains a fluorescent agent that reacts to black light, making it easy to visually confirm the coated areas. As it is UV-curable, it cures in a matter of seconds to tens of seconds, significantly reducing work time.The resulting coating film provides excellent insulation, improving the insulation reliability of narrow patterns on printed circuit boards. It protects circuit boards from corrosive gases found in hot spring areas and from salt damage in coastal regions. Four variations are available, differing in volume and color.
