Pan Jixin's prospective technology of waterborne coatings -- three coats and two ovens / three coats

Pan Ji new material prospective technology——

Three coating and two baking (3c2b) / three coating and one baking (3C1B) waterborne coating

Pan Jixin material "three coating and two drying" / "three coating and one drying" is a new coating process. In order to meet the development needs of energy conservation and environmental protection, on the basis of ensuring the coating performance, the coating industry is bound to develop environmentally friendly industrial coatings and coating processes with low energy consumption and low VOC. 3c2b / 3C1B coating process which can save energy and reduce primer drying process and the application of water-based environmental protection coatings have become the development trend of industrial coating.

1、 Disadvantages of traditional coating process (3b3c)

1. At this stage, the coating method commonly used in the field of metal coating such as hardware, household appliances and vehicles is that the primer is water-based electrophoretic coating. After drying, the primer is sprayed with solvent based color paint, and then sprayed with solvent based gloss paint after drying. The three coating and three drying process. This coating method has serious energy waste and great environmental pollution, which completely deviates from the development trend of environmental protection.

2. At this stage, due to the large difference in product structure between water-based electrophoretic coating, solvent based color paint and gloss paint, there is often poor adhesion between primer and color paint, peeling between coatings, which seriously affects the performance of products.

2、 Characteristics of Pan Jixin's "three coating and two drying" (3c2b)

1. 3c2b water-based coating adopts the process of "three coating and two baking" to provide a good appearance of paint film and form multi-layer paint film on the workpiece. The primer adopts water-based electrophoretic coating to improve the corrosion resistance of metal workpiece; Color paint and gloss coating are water-based coatings with excellent aging resistance.

2. 3c2b water-based coating is a single component coating. The workpiece is coated with electrophoretic coating and primer. After flash drying at 80-100 ℃ for 3-5min, it is directly sprayed with water-based color paint. The two coatings are cured at the same time, polished and repaired (if necessary), and then sprayed with water-based gloss paint. All three coatings are hydrated, the adhesion between coatings is obviously superior to the three coating and three drying process, and there is no color migration between the three coatings.

3. 3c2b water-based coating adopts special nano silver ion antibacterial technology, which has excellent antibacterial performance and fresh construction environment.

3、 Advantages of Pan Jixin's "three coating and two baking" (3c2b)

1. The electrophoretic primer does not need to be baked to simplify the coating process;

2. Cancel the primer grinding and repair process;

3. Reduce the times of baking and grinding, and save energy and processes;

4. Reduce VOC emission compared with solvent based coatings.

4、 Pan Jixin's "three coating and one drying" (3C1B) process

If the customer has good control over the construction process, the baking and polishing repair process of the color paint can be saved. After the color paint is flash dried, the gloss paint can be sprayed directly, and the three layers of coating film can be cured at the same time. On the basis of three coating and two drying, the process is further simplified and the energy cost is saved.
