Silicone products are known for their superior elasticity and superior high tear strength properties. Products made from silicone materials have a long service life, comfortable hand and flexible texture, which is unmatched by other materials. So how can we make the characters on the surface of the silicone button wearable?
Everyone should know that the surface of the silicone button has a transparent protective layer. The function of the silicone button is to protect the characters on the surface of the silicone button. It is not easy to be worn during use. This layer should be closely connected with the silicone keyboard. The protective layer is transparent and hard.
For the wear resistance of the surface of the silicone button, the first thing we think of is to spray PU ink on the surface of the silicone button. The surface of the silicone button can effectively protect the font, and it can also meet the protection layer and the silicone keyboard. Several requirements. As for the hardness, it is also true that the feel is indeed harder than the unsprayed PU, and the process cost will not increase too much. For products that are not too demanding for wear, the choice of PU on the surface is sufficient.
If the wear resistance of the characters is demanding and the hardness of the protective layer is high, the PU may not meet the requirements. General silicone products manufacturers will recommend you to use the surface dispensing process, that is, a layer of crystal glue on the surface of the silicone button. In this way, all the requirements can be met, and the characters are basically not worn away.
