Copper or copper alloy discoloration prevention liquid and discoloration prevention method |
| abstract |
(57) [Summary] [Purpose] Discoloring prevention liquid and discoloration prevention for copper or copper alloy that have excellent discoloration prevention effect under normal environment, excellent heat resistance, and high adhesion to resin at low temperature. Establish a method. The present invention comprises a silane coupling agent and a metal or a salt thereof which is more noble than copper, and further contains water or an organic solvent as a solvent, and further contains a pH buffering agent and / or a surfactant as required. A discoloration prevention liquid. The anti-tarnish treatment is performed by immersing copper or a copper alloy in the anti-tarnish liquid, or by spraying or spraying the anti-tarnish liquid on the copper or copper alloy. |
