Etching resist ink Фоторезист KSM-UV201 UV curable (Blue)

UV curing etching resist ink for acidic etching solution
(KSM-UV 201)
KSM-UV 201 is UV curing etching resist ink for acidic etching solution, which is used for making patterns on copper-clad laminates by means of acidic etching. The cured film can provide good adhesion, clear printing line, high resolution , resistance to the etching of acidic CuCl₂/FeCl₃ solution and fast removing coating.
