UVER-Il is an alkali-soluble, UV-curable resist ink used to produce circuit boardgraphicsand otherartifacts with corrosion-resistant graphics.It has high resolution and can resist acid etching, ordinary copperplating, brightcoppertin plating and nickel gold plating. The coating film has a high hardness (2H), comparedwith the general solvent-based resist ink, greatly reducing the line breakagedue toscratching, improve the yield rate.UVER-Il in the ultraviolet light irradiation canbecured, not subject to the influence of the working environment and climate, greatlyimproving the production efftiency, and does not contain solvents, has a highacidvalue, do not need to increase the concentration of Na0H in the removal of thefilmsolution can be removed from thefilm, thus avoiding the substrate color darkening, thecolor of the substrate can be removed from the film, The color of the substratedarkensand the insulation of the finished product decreases, and can be completelydissolvedin caustic soda (Na0H) solution without the need to increase the filtrationequipment, simplifyingthemaintenanceofeguipmentand film removal solution.
