Techniseal and Tarniban® Proven Protection for Silver Deposits Under the Harshest Conditions
Cranston, RI, USA – Techniseal and Tarniban® KS II are Technic’s premier silver anti-tarnish processes designed to prevent yellow discoloration under the harshest conditions. Both are production proven processes that can be used in barrel, rack, and high-speed reel-to-reel applications.
Techniseal is Technic’s most powerful silver anti-tarnish. The electrolytic process deposits a nano-scale inorganic coating on the surface of the silver deposit within 5 seconds. This high-speed deposition makes it particularly suited for reel-to-reel applications. Silver deposits treated with Techniseal pass all ammonium and potassium sulfide tests. Additionally, Techniseal will prevent silver discoloration caused by high-temperature exposure, making this product especially useful for automotive “under the hood” and LED applications. Producers of silver plated castings are also using Techniseal to prevent discoloration on the product after long-term exposure to temperatures above 232 °C and under humid storage conditions.
Technic’s Tarniban® KS II is an organo-thiol process that can be used in immersion or electrolytic applications. It forms a SAM (Self-Assembled Molecular) barrier layer on silver deposits and prevents discoloration at temperatures below 232 °C. Tarniban® withstands all standard ammonium and potassium sulfide tests and provides a more lubricious coating to the silver deposit. Rack and barrel applications require only simple immersion for at least 30 seconds. For reel-to-reel applications, Technic recommends an electrolytic treatment, providing full protection of the silver deposit in just 5 – 10 seconds.
