Pan Jixin's 'Three-coating and two-bake' / 'Three-coating and one-baking' is a brand-new coating process. In order to meet the development needs of energy saving and environmental protection, the coating industry is bound to develop low energy consumption and low VOC on the basis of ensuring coating performance. Environmentally friendly industrial coatings and coating processes. The 3C2B/3C1B coating process and the application of water-based environmentally friendly coatings that can save energy and reduce the primer drying process have become the development trend of industrial coatings.
First, the drawbacks of the traditional coating process (3B3C)
1. At this stage, the coating method commonly used in metal coatings such as hardware, home appliances, and transportation is that the primer is an aqueous electrophoretic coating. After the primer is dried, the solvent-based paint is sprayed. After the paint is dried, the solvent is sprayed. Type varnish, three-coating and three-baking process. This type of coating method is a waste of energy, and it has a large environmental pollution, completely deviating from the development trend of environmental protection.
2. The current coating method is due to the large difference in product structure between water-based electrophoretic coatings and solvent-based paints and varnishes. It is often the case that the adhesion between the primer and the paint is poor, and between the coatings occurs. The stripping, seriously affecting the performance of the product.
Second, the characteristics of Pan Jixin's 'Three Coatings and Two Drying' (3C2B)
1. 3C2B water-based paint, using 'three-coat two-bake' can provide a good appearance of the paint film, forming a multi-layer paint film on the workpiece, the primer adopts water-based electrophoretic paint to improve the corrosion resistance of the metal workpiece; 2. The varnish coatings are all waterborne coatings with excellent aging resistance.
2. 3C2B water-based paint is a one-component paint. The workpiece is coated with electrophoretic paint. After 80-100°C flashing for 3-5min, the water-based paint is sprayed directly. The two coats are cured at the same time. Grinding and repairing (if needed) After spraying the water-based varnish. The three-layer coating is all water-based, the adhesion between the coatings is obviously superior to the three-coating three-bake process, and the color migration between the three coatings is not carried out.
3. 3C2B water-based paint, using special nano silver ion antibacterial technology, has excellent antibacterial properties, and the construction environment is fresh.
Third, the advantages of Pan Jixin's 'Three Coatings and Two Drying' (3C2B)
1. The electrophoretic primer does not need to be baked to simplify the painting process;
2. Cancel the primer grinding and repair process;
3. Reduce baking, grinding times, energy saving and process;
4. Relative to solvent-based coatings, reduce VOC emissions.
Fourth, Pan Jixin's 'Three Coatings and One Drying' (3C1B) Process
If the customer controls the construction process better, the paint baking and grinding repair process can be omitted. After the paint is flashed, the varnish is directly sprayed, and the three-layer coating is simultaneously cured. Further on the basis of three coatings and two dryings. Simplify the process and save energy costs.
