The protective film is then immersed or sprayed on the surface with a repeated coating method. The bottom layer of the impregnated paint is a paint type with good sealing performance to improve its protective performance; the sprayed part requires the use of a paint with high hardness to increase the abrasion resistance of the paint film and prolong its use time, thereby ensuring the long-term use of the buttons.
