By performing blast treatment, the adhesion of the paint is greatly improved, resulting in a beautiful appearance.
Blasting processing is a type of "substrate adjustment" that involves simultaneously spraying compressed air and abrasives to collide the material and the abrasives at high speed. The abrasives that collide at high speed scrape away the surface of the material, exposing it. The surface of untreated materials often has a lot of oxidation films (mill scale), rust, and impurities attached. If these impurities are not removed, the paint will quickly peel off. Careful substrate adjustment can prevent painting defects in advance. Blasting does not use chemicals and offers a wide variety of abrasives, allowing processing regardless of the material type, which is a significant advantage. Additionally, it is very effective not only for painting but also as a pre-treatment for plating, lining, and coating. The countless irregularities created by the impact of the abrasives increase the contact area and allow for the 'anchor effect' where the material penetrates into the gaps and hardens. This effect significantly increases adhesion, resulting in a more beautiful finish for the paint. Paint that is free of impurities and strongly adheres is said to have a rust prevention effect that lasts 3 to 4 times longer compared to regular paint. This can reduce the frequency of repainting, repairs, and maintenance, extending intervals and thereby saving resources and costs.

basic information
◎Surface preparation This refers to the process of making the substrate more suitable for painting. Surface preparation involves removing rust, dirt, and deteriorated paint films from the substrate, and the created roughness significantly improves the adhesion of the paint. The causes affecting the lifespan of the paint are largely attributed to surface preparation, accounting for about 50%, making it a crucial process. 【Impact/Causes on Paint Film Lifespan】 https://www.nc-net.or.jp/company/98405/product/detail/179473 ◎Mill scale Also known as black scale, it is an oxidized film that forms on the surface of steel during its manufacturing process. In the hot rolling method, the metal is heated to high temperatures, causing it to combine with oxygen in the atmosphere, resulting in black scale. Even when painting, black scale generally has poor adhesion, so it is common to remove it. 【List of Typical Painting Defects: Causes and Countermeasures】 https://www.nc-net.or.jp/company/98405/product/detail/192232/
