What are the characteristics of non-phosphorus coating agent

Phosphorus-free coating agent is a nanometer water-based metal surface coating pre-treatment agent prepared with environment-friendly materials. Its characteristics are as follows:

1. Environmental protection of film coating agent: it does not contain phosphate, nitrite, chromate, heavy metals, volatile organic compounds and other pollutants, and is an aqueous agent, without sediment and discharge.

2. Energy saving of coating agent: the traditional phosphating solution treatment process usually adopts low and medium temperature phosphating, which requires heating the phosphating solution to 35 ℃~55 ℃, constant temperature and energy consumption; This product can be used at normal temperature without heating and energy saving.

3. The film agent can improve the production efficiency: the treatment time of the base material is short, the spray production line is usually 30~60 seconds, and the soaking production line is usually 2~5 minutes, which greatly improves the production efficiency.

4. Easy to use and maintain: it only needs the combination of film agent BX-01 and accelerator BX-02, while the phosphating solution needs to be added with various preparations. No slag deposit, no need to stop the line for slotting, no damage to nozzle and other related equipment, saving time and money.

5. Excellent adhesion: the film thickness of this product is nanometer, with good compactness and uniform film formation, without surface adjustment and passivation treatment, so that the adhesion of metal substrate and coating is extremely strong, and the corrosion resistance time of metal is prolonged.

6. Wide range of applications: This product is generally applicable to a variety of materials, such as cold rolled sheet, hot rolled sheet, carbon steel, cast iron, galvanized sheet, aluminum sheet, aluminum alloy, zinc alloy and so on, so that the production line does not need to change the treatment fluid when processing workpieces with different substrates, saving time, money and efficiency.

7. The process flow is simple: just degrease → wash → wash → film treatment → wash → dry.

8. Low processing cost: the processing area per kilogram is not less than 150 square meters, which greatly reduces the production cost of users.

9. The coating agent is less corrosive to the workpiece.
