Silicone keypads are easy to absorb dust under normal conditions,so during the production process,we will spray a thin layer of hand oil on the surface of the silicone buttons,which can prevent dust and make the hand feel better.The main effect of oil spray is to improve the feel and aesthetics of the product,so that the product maintains a smoother and more three-dimensional feeling.

There are three different processing methods for silicone button spray:

  1. Color spray oil: Color spraying oil is to spray a layer of visible ink on the surface of the silicone button,and the color can be adjusted according to the customer's demand for the product.

  2.Spray extinction: Matte ink is a kind of matte touch ink,its characteristics are similar to PU ink,but spraying matte ink will make the surface of the silicone button appear matte, and can spray out the effect of matte, and the feel is smoother in comparison.

  3. Spray PU: PU refers to a kind of ink,which has the characteristics of strong adhesion,wear resistance,and good transparency.The silicone keypad sprayed with PU also feels very good and is very wear-resistant.It is also a commonly used oil spray for silicone keypads.
