Silicone surface activation treatment, commonly known as UV Plasma, is to irradiate the silicone product with UV light, so that the silicone oil inside the silicone is precipitated on the surface of the silicone, and the precipitated silicone oil is cured to remove static electricity and sterilize; at the same time, the surface of the silicone is oxidized by XD O3, Form a protective layer on the surface of silica gel, make the molecular structure of the surface layer of silica gel more compact, remove the stickiness of the surface layer of silicone, and make the silicone products achieve the effect of no static electricity, no dust absorption, and smooth hand feeling.
Silicone surface activation treatment has the advantages of antistatic, soft and delicate hand feeling, smooth oil film appearance, uniform surface haze and good skin contact feeling. Compared with traditional oil injection, the surface activation treatment process of silicone is more environmentally friendly, and "never loses oil", and there are no defective products in the process. Currently in wearable (watch strap/VR), kitchen utensils, sex products (other built-in appearance parts are also available) applications.
The principle of surface activation treatment of silicone is to cut off the molecular chains on the surface of silicone by using a semiconductor extremely low-length and high-energy source, so that the molecular structure of the silicone surface can be reorganized to produce a nano-reactive layer, so that the surface of silicone can achieve anti-static ability, and the surface is more stable and smooth.
1) Using a high-magnification microscope, it can be found that the surface after activation is smoother than before activation.
2) On the surface of the silicone at a height of 10cm, evenly sprinkle the paper fiber and shake it for 3 times to compare the effect.
|Project||Silicone surface spraying||silicone surface activation treatment process|
|Surface Durability||limited number of times||good|
|Surface Feel||Very good (before falling off)||very good|
|Tape Test||related to thickness||100%|
|Chemical Resistance||will fall off after a certain time||excellent|
|Color||Change (strong whitening)||Slight whiteness and luster towards brighter direction|

1) It is only activated on the surface of silicone and does not affect the material properties.
2) No solvent, no paint, no derivative environmental issues.
3) Excellent durability.
4) No problems of coating wear, precipitation and migration.
5) No increase in thickness, stable size.
6) Color stability.
