和硅烷处理剂有明确认知。 Recently, the editor and the netizens discussed and exchanged the technical problems of the metal coating pre-treatment process in the forum. Some netizens mentioned which process effect of ceramic and silane is good. Next, the editor and I will explain it in detail. Later, he had a clear understanding of potting agents and silane treatment agents.
Application scenarios of potting agents (Figure 1)
Comparison of pottery and silane
Pottering agent is a kind of phosphate-free reactive pretreatment chemical, which does not contain phosphorus and heavy metals. The main ingredients are zirconium salt, silane, and zirconium salt silane compound type. The silane treatment agent is an organic silane as a main raw material, which belongs to a part of a potting agent, and is called a silane potting agent. Zirconium salt is extremely difficult to dissolve in water and very difficult to dissolve in acid. Silane is organic and has high requirements on the process. Only deionized water can be used. Therefore, the stability of silane is extremely poor and it has slag.

The role of potting agent
The potting agent is mainly based on zirconium salt, and the color of the potting film is golden yellow. Suitable for surface treatment of steel, zinc and aluminum before painting. It can replace phosphating solution before painting. It can enhance the adhesion and corrosion resistance of the coating. It can form a film with strong stability on the surface of aluminum, iron, and galvanized sheet. Therefore, it has strong corrosion resistance and good adhesion with the coating. No phosphorus, no chromium, weakly acidic to neutral, no volatility, no precipitation.
How to use potting agent
First fill 80% of the water into the tank, add 20-30kg of potting agent, and then add adjuster and neutralizer to adjust the PH value to the working range. Add water to 1000L. The best treatment is stainless steel tank or PP plastic tank.
