Anti-tarnishes can be an effective post-treatment solution for electroplated materials. Anti-tarnishes are utilized to prevent oxidation from developing on the metal surface, as well as to provide better solderability and higher corrosion resistance. They are particularly efficient in preventing oxidation during prolonged storage, especially when the storage temperature is not constant, as this may accelerate the oxidation process due to humidity developing on the parts.
Technic supplies a wide selection of anti-tarnish chemistry for industrial manufacturing applications, including advanced solutions for copper, copper alloys, gold, silver, tin, tin alloys, and others.
For Silver: Organic, thin colorless film with good resistance to corrosion, improved solderability and no effect on electrical performance.
For Silver and Copper: Thin colorless film with good resistance to corrosion, improved solderability and no effect on electrical performance.
For Silver and Gold: Can be applied by immersion or anodically for increased protection. Passes sulfide stain tests.
Post treatment process designed for use on tin and tin alloy deposits which are subjected to post-plate thermal exposure in high humidity/steam environments.
Post treatment process for tin and tin alloys that protects tin deposits from oxidation and discoloration following post-plate high temperature dry thermal exposure.
Technic's selection of industrial post treatment chemistry also includes passivation chemistry, coatings, and metal strippers. Additionally, Technic offers industrial Pretreatment Chemistry, Electrolytic Plating Chemistry, Electroless Plating Chemistry, and Immersion Chemistry.
