Human technology is leaping forward. From the texture preparation button-type mobile phone five years ago, through several years of rapid development, Samsung, Apple's share of smartphones continues to expand. The old mobile phone king "Nokia" also gradually failed, ending with "innovation" by Samsung and Apple. Today, smartphones continue to exert their strength, using a technology and a technology, constantly using new technology in the use of smart phones, so that everyone feels the convenience and convenience brought by the technology.

From the appearance and feel of the mobile phone alone, from the colorful mobile phone case of the Nokia era, "changing with you", and then to the rubber raft, also known as elastic paint. People feel soft and comfortable when they hold the phone, but they are full of elasticity. However, the elastic paint film also has the disadvantage of death. Compared with simply absorbing water, it is often said to be sticky. In the case of high humidity or humidity in spring, the outer casing of the mobile phone with rubber elastic paint will have a wet and sticky feeling when it is taken, and the scratch resistance (elastic paint has a certain anti-scratch will be actively corrected) Inadequate, accidentally scratched with nails and even showed the appearance of scratches and whitening (a certain amount of matte powder was added to the elastic paint).

Therefore, the elastic paint is gradually being screened, and today's smart phone manufacturers such as Apple and Samsung are inconsistently developed from the smooth finish to the sand surface (also known as the matte feel). The sand-finish paint film has good scratch and abrasion resistance, because it has a dull matte effect, which makes people look very comfortable and feels smooth. When holding the hand, it is simple and stable, followed by the screen of the mobile phone. It is getting bigger and bigger, and it is more in line with everyone's needs in this respect. The apple-led smartphone case first uses a matte paint (which can be used with Siluoer texture preparation) to give an elegant and comfortable sand surface (also known as a matte finish). It is very addictive. Siluoer texture preparation has excellent hand feeling, stable particle size, affordable price, environmentally friendly and halogen-free, and has become the first choice for sand topcoat.
