FCU-2 Anti-corrosion and anti-tarnish agent for copper and copper alloys

FCU-2 Anti-corrosion and anti-tarnish agent for copper and copper alloys

1 copper or copper alloy by pretreatment degreasing, pickling chemical polishing gloss surface, after FCu-2 treatment, can maintain long-term gloss does not change color, and can prevent chemical or reduce physical corrosion (such as AC contactor frequent opening and closing caused by "ablation"). 2. The anti-discoloration film is firmly combined with the polished substrate, and the film is a transparent film, which will not change the gloss. 3. The anti-discoloration agent and copper, copper alloy, silver, zinc, nickel, stainless steel film formed no resistance, will not reduce the original conductivity of the base metal. 4. The film can be used at room temperature to 100 ℃, with good temperature resistance. 5. For the removal of poor film layer can be removed with ordinary alkaline degreasing liquid.

FSN-2 Tin anti-high temperature discoloration protective agent

FSN-2 Tin anti-high temperature discoloration protective agent

1. It can be used as stock solution or simply diluted to 30-80% with deionized water before use. 2. The processing time is short, and the effect is better in the roll-to-roll high-speed electroplating equipment. 3. Acidic process, compared with the traditional alkaline post-treatment/neutralization treatment, the effect is more significant. 4. It can stabilize the surface of tin coating and is not easy to oxidize compared with the tin coating without post-treatment. This process is effective in controlling reflow discoloration and oxidation.
