What is atomic gray printing? Let me explain to you that the atomic gray mark is the edge of the coating under the topcoat visible system, or the grinding mark near the original repair area. This is the so-called atomic gray mark. I don't know if you can see it or not, just think about it slowly. Next, let's talk about why this happens?
The cause of atomic gray printing
1) The use of atomic ash on unsuitable substrates results in tension differences.
Atomic ash is used on inappropriate substrate, resulting in tension difference; before spraying polyester atomic ash, the substrate shall be analyzed first, and polyester atomic ash can only be used on bare steel or protective green primer.
2) Before grinding, the base material has not been degreased or degreased improperly. During grinding, the edge is out of shape, leaving an irregular edge around the repair area.
Before grinding, the base material has not been degreased or the degreasing is improper, which means that the atomic ash and the base material are not attached well. During grinding, the edge is out of shape, leaving an irregular edge around the repair area; therefore, we should thoroughly degrease before grinding.
3) The substrate to be scraped and coated with atomic ash shall be polished with fine sandpaper. After grinding, due to poor adhesion, the edge of atomic ash is out of shape.
For the substrate to be scraped and coated with atomic ash, use fine sandpaper to polish; after polishing, because of poor adhesion, the edge of atomic ash is out of shape; in this case, we should use the recommended thickness sandpaper when grinding and edging.
4) The repair interface area is not properly ground.
The repair interface area is not properly ground, and the repair interface area is fully ground
5) After the base material is polished too rough and the atomic ash is polished and leveled, there are still obvious sandpaper marks.
After the base material is polished too rough and the atomic ash is polished flat, there are still obvious sandpaper marks; therefore, the correct grinding steps should be adopted.
6) Minor patching areas in the paint system are not adequately edged.
The small patch area of the paint system is not fully ground, so the interface area of the small patch is fully ground.
7) The filled area is not smooth enough to be raised compared to the surrounding area.
The filling area is not polished smooth enough and protrudes significantly compared with the surrounding area; in this case, polish with grinding pad and touch the surface of the filling area from time to time.
8) Part of the atomic ash is scraped on the old paint film, and irregular edges are formed around the filling during grinding.
Part of the atomic ash is scraped on the old paint film to form an irregular edge around the filling area during grinding; the repair area is thoroughly polished.
9) The scraping of atomic ash is not smooth, and the edge is not polished.
The scraping of atomic ash is not smooth and the edge is not polished; when scraping and coating atomic ash, the edge shall be grinded.
In case of atomic gray mark on automobile paint surface, the repair area shall be polished, repaired to make it smooth, and then sprayed again.
Solution of atomic gray printing
1) Atomic ash can only be used on bare steel or protective primer.
2) Atomic ash shall be degreased thoroughly before grinding.
3) When grinding and edging, it is recommended to use coarse sandpaper.
4) Fully grind the repair interface area.
5) Take the correct grinding procedure.
6) Fully edge the interface area of small patch.
7) Grind with a grinding pad and touch the surface of the filled area from time to time.
8) Polish the repair area thoroughly.
9) When scraping and coating atomic ash, the edge shall be grinded.
10) Polish and trim the repair area to make it smooth, and then spray again.
Well, today, the solution of atomic gray printing on automobile paint surface introduced by Xiaobian is here. I don't know if you have a deeper understanding of atomic gray printing after listening to Xiaobian's introduction? I hope the introduction of Xiaobian can help you.
