Is the most common wet coating deposition process we see glass coated with silver mirror, in some places is still in use today. Common wet French pattern on the plating items is to use chemicals to produce chemical reaction, reaction of adhesive on the surface of plated items, and combine together to form a layer of coating.
Wet coating work elements are:
1. Chemical agents to participate in chemical reactions
2. The chemical reaction pool
3. The auxiliary additives
4. The catalyst
5. Reaction electrode
We can see that due to the preparation of coating chemical reaction method, people can't accurate control of chemical reaction in the pool every small areas of the situation, to a great extent, people couldn't sophisticated control layer in the process of production of uniform thickness. In quite a number of cases is plated items do not allow to have a chemical reaction. For example, in the single pervious to light glass coating production such as glass and chemical reaction is likely to damage of the glass surface, pervious to light fall, it would be lost to the coating. Were the most serious questions, most used chemicals, auxiliaries, strong catalyst are polluting, some are highly toxic, he brings to the human and the nature, even catastrophic damage is huge. Some film system cannot be prepared with chemical method.
