MG Chemicals 4200UV – UV Curable Conformal Coating
UV Curable Conformal Coating 4200UV is a 1-part, UL-certified conformal coating formulated for rapid cure upon exposure to UV light. It is a low viscosity coating that retains high fluorescence after curing for ease of inspection, curing to a smooth, glass-like finish. The coating contains a secondary moisture cure mechanism that allows for curing in shadowed areas. 4200UV is a cost-effective option for large volume projects where both fast turn-around and higher throughput are required. It creates a rugged barrier protecting circuits from humidity, corrosion, fungus, dust, thermal shock and high voltage arcing.
