Surface treatment for firmly adhering a non-stick "fluoropolymer coating" to the substrate. This explains "blasting."
■What is blasting? Blasting is a surface treatment method that involves spraying blast materials (various abrasive particles) onto the surface of a product using compressed air or similar means to remove rust and dirt from the substrate surface. The particles that collide with the surface act as "impact" or "cutting." Although the energy of a single blast particle is minimal, the continuous bombardment of countless particles results in a significant effect on the surface. ■Blasting as a pre-treatment In addition to cleaning the surface, blasting increases the surface area through roughening, which generates an anchor effect that greatly enhances adhesion during coating processes. Therefore, it is extremely effective not only for fluoropolymer coatings but also as a pre-treatment for processes such as thermal spraying and plating. Additionally, blasting can improve the wettability of liquids. To fully realize the performance of fluoropolymer coatings, pre-treatment is a crucial process. At Yoshida SKT, we select blast materials and treatment methods suitable for coatings and substrates to process fluoropolymer coatings. *For more details, please check the link below or feel free to contact us.

basic information
Principles and Considerations of Blasting ■ Blasting removes material through the impact force of blasting particles. ■ The strength of the impact is determined by the weight and pressure of the blasting material. ■ Surface roughness can be adjusted by the size of the blasting particles. ■ It is unsuitable for materials that absorb impact forces, such as rubber. ■ Blasting on thin plates can cause warping due to differences in surface area.
