Generally, the main body of the silicone pressure sensitive adhesive is formed by mixing liquid silicone rubber and MQ silicone resin in a certain ratio. Silicone rubber can increase the fluidity of the pressure sensitive adhesive, thereby increasing the interfacial adhesion and the initial tack. The MQ silicone resin has a great influence on the adhesive properties of the pressure sensitive adhesive, because the molecular weight of the MQ silicone resin changes the viscosity and cohesive strength of the pressure sensitive adhesive. When the molecular weight of MQ silicone resin is about 3000, the pressure sensitive adhesive has the highest cohesive strength, good viscosity, high peel strength and good thixotropy.
