詳細
A silver plating solution for depositing thin uniform layers of bright silver by an electroless immersion process. The process operates by an electroless displacement of base metals by silver brought about by a difference in the EMF potentials. The product is designed to produce a bright silver plating on copper, brass and copper alloys with excellent adhesion. Plating occurs on other metals with varying degrees of adhesion.
- Operating temperature: 90 °C
- Plating time: 5-10 minutes
- Tank: Pyrex glass

What are the main solvents used in this solution? I am uncertain as to what to write on the hazardous waste disposal tag in terms of percentages. Thanks!

2 questions: Does this work on silver metal? (i.e. growing Ag on top of Ag) Does this only replace the top metal layer with Ag, or does it actually grow/deposit a Ag layer? In other words, is there any thickness control? Thank you very much!

As mentioned in the "Properties" section, this product was designed to produce a bright silver plating on copper, brass, and copper alloys. This silver plating solutions should work on silver as well, however, it will depend on the degrees of adhesion.
The silver ions will attach to the surface of the metal layer. The plating process occurs by an electrochemical reaction. For example, when the silvering solution is applied to a clean copper surface, two electrochemical half-reactions occur. Silver ions in solution coming from silver chloride are reduced to silver metal that is well adhered to the copper surface. At the same time, the copper metal is oxidized (it corrodes) to form copper ions in solution. This is a galvanic effect where the more active metal (copper) is oxidized and the ions from the more noble metal (silver) are reduced. Because the copper causes the silver ions to be reduced, the copper acts as the reducing agent. The simplified form of the overall reaction is as follows:
Ag+ + Cu0 → Ag0 + Cu+
We have not tested the thickness control for this item and can not validate that information for this product, however information on thickness recommendation for Silver plating is as follows:
Minimum- 7.6 microns for soldered articles
12.7 microns for corrosion protection of nonferrous basis metals & to increase the electrical conductivity of those metals
2.7-254 microns for electrical contacts, depending on factors such as pressure, friction and electrical load役に立ちましたか？
