Post-Treatment for Connector Finishing
Technic supplies post-treatment solutions for Connector finishing applications, to further enhance the characteristics and properties of electroplated metal surfaces.

Techniseal AG
Techniseal AG is a chrome-free cathodic electrolytic passivation system. This unique product provides a transparent nano-scale protective coating on silver, which greatly improves corrosion resistance and minimizes appearance degradation. Techniseal AG protects silver from tarnishing during exposure to heat and/or sulfur corrosion testing. This product can also be applied directly on copper for specific applications.
Tarniban® E260
Tarniban® E260 is a post-treatment process, which effectively protects tin and tin-alloy deposits from oxidation and discoloration when subjected to thermal conditioning (heating, reflow, etc.).
Tarniban® C48/C50
Tarniban® C48/C50 minimizes deposit discoloration during storage and provides improvements in solderability performance after steam age pre-conditioning. Tarniban® C48/C50 also minimizes corrosion-induced tin whisker growth caused by high temperature/humidity exposure.
Tarniban® KS II
Tarniban® KS II is an organic thiol post-treatment process, which effectively protects silver surfaces from oxidation/tarnishing. It may be used as an immersion-only process or applied anodically for increased protection.
