In recent years, China's chemical industry has developed rapidly. Organic silicon pressure-sensitive adhesive is a commonly used chemical material, a pressure-sensitive adhesive with organic silicon polymer as the main body. Compared with the traditional acrylate pressure-sensitive adhesive and rubber pressure-sensitive adhesive, silicone pressure-sensitive adhesive has many advantages. Now let's take a closer look at silicone pressure-sensitive adhesive.

The silicone pressure-sensitive adhesive has good adhesion to the materials that are difficult to stick, so the back of the substrate or the release paper of the label cannot use the common silicone release agent. Therefore, when the silicone pressure-sensitive adhesive is heated, with the increase of temperature, some impurities and small molecular substances volatilized first, and then some unstable groups and side chains break. When the temperature rises to a certain extent, the large molecular chains begin to decompose to form small chain segments. The higher the decomposition temperature of silicone pressure-sensitive adhesive, the better its high temperature resistance.

Four categories of silicone pressure-sensitive adhesive:
① Hot melt silicone pressure-sensitive adhesive
Hot melt silicone pressure-sensitive adhesive has the advantages of non pollution, safety and environmental protection, low cost, and convenient construction. Compared with some adhesives, spray guns and sprayers are required. Hot melt silicone pressure-sensitive adhesive can be applied with traditional equipment.

② Dissolved silicone pressure-sensitive adhesive
Dissolved silicone pressure-sensitive adhesive is seldom used, mainly because its solid content is relatively low. A large amount of solvents are used when using it, so a large amount of raw materials will be lost, which will cause environmental pollution. Therefore, this adhesive is seldom used, but its performance is very good.

③ Lotion silicone pressure sensitive adhesive
Searching for lotion silicone pressure-sensitive adhesive, we can see that there is not much information on the Internet. This is because the active agent should be added to the lotion silicone pressure sensitive adhesive when it is used. This solvent will have a certain impact on the performance of the adhesive.

④ High solid gold type and insoluble silicone pressure-sensitive adhesive
In recent years, many enterprises have responded by vigorously advocating environmental protection, health and pollution-free. Therefore, high solid gold type and insoluble silicone pressure-sensitive adhesives are also gradually developed. Its advantage is that it does not require solvent dilution when used, and it is easy to mix, healthy and environmentally friendly.
