What are the advantages and disadvantages of baking varnish and spray painting?

Baking varnish and spraying varnish belong to different processes, mainly acting on the board surface materials. What are the advantages and disadvantages of baking varnish and spraying varnish? Let's take a look.

1. What are the advantages and disadvantages of baking varnish and spraying varnish

Advantages and disadvantages of baking varnish: The paint film of baking varnish is smooth, flat, colorful, not easy to fall off, dirt-resistant and waterproof, but the process is relatively complicated. Not only three coats of primer and four coats of topcoat are required, but each coat of paint must be sent to the baking room for baking after construction.

Advantages and disadvantages of spraying varnish: Spraying varnish has rich colors and is relatively simple to apply. It only needs to be mixed and then the surface of the board is evenly sprayed with paint, and finally dried naturally. However, the edge treatment is relatively rough, and the paint film is prone to unevenness. If the construction is improper, there will be lines, and it will feel granular when touched, and the paint film will also fall off.

2. What should be paid attention to in the construction of baking paint

1. Pay attention to the construction process

The construction of baking paint is very rigorous. As we can know from the above, it needs to be constructed at least 7 times. If it is baked again, it needs 14 times. Each construction can not be ignored, especially the first time, which is carried out on the substrate. The dust, moisture and oil on the surface of the substrate need to be cleaned up. Make sure it is clean before construction, otherwise the paint film will easily fall off or defects will occur later.

2. Pay attention to detail processing

When baking paint, pay attention to the edges and corners of the four sides of the substrate. It must be handled in place to avoid uneven paint film and keep the color consistent.

3. Avoid grain

The board after baking paint process should be smooth and consistent, and basically there will be no obvious grain. You can observe the paint film in the side light area to see if there is orange peel phenomenon. If there is, it needs to be reworked. At the same time, you can also touch the surface of the paint film with your hand. If there is a granular feeling, it will not work.
