Silicone resin plays a vital role in the production of pressure-sensitive adhesives, and its unique chemical properties give pressure-sensitive adhesives excellent properties.The following are the specific applications of silicone resins in the production of pressure sensitive adhesives：


Thickening and strengthening effect: Silicone resin mainly plays a thickening and strengthening effect in pressure-sensitive adhesives.The silicon hydroxyl group or vinyl group in its molecular structure can condense with the hydroxyl group of silicone rubber or through hydrogen-containing siloxane under the action of a catalyst, thereby enhancing the cohesion and adhesion of the pressure-sensitive adhesive.


As a commonly used type of silicone resin, MQ silicone resin has a significant molecular mass on the bonding properties of pressure-sensitive adhesives.When the molecular mass is high, the pressure-sensitive adhesive has high cohesion strength and good viscosity; if the molecular mass is low, the interfacial adhesion can be improved, but the cohesion strength is relatively low.


Adjust the properties of pressure-sensitive adhesives: By adjusting the material ratio of silicone resin to rubber, the fluidity, initial viscosity and peel strength of pressure-sensitive adhesives can be accurately controlled.


With the increase of the amount of silicone resin, the fluidity of the pressure-sensitive adhesive increases and the initial viscosity increases; while the decrease in the amount of resin is not conducive to deep crosslinking, the reinforcing effect is poor, and the cohesion is reduced.


This adjustability makes silicone resins have wide application prospects in the production of pressure-sensitive adhesives.


Improve temperature resistance: The introduction of silicone resin has significantly improved the temperature resistance of pressure-sensitive adhesives.In a high temperature environment, the silicone resin can maintain stable chemical properties and prevent the pressure-sensitive adhesive from failing due to thermal decomposition.


This makes silicone pressure-sensitive adhesives have significant advantages in high-temperature industrial applications, electronic component protection and other fields.


Improve bonding ability: Silicone resins can bond a variety of low-surface energy materials that are difficult to stick, such as untreated polyolefins, fluoroplastics, polyimides, etc.This excellent bonding ability makes silicone pressure-sensitive adhesives widely used in electronics, automobiles, aerospace and other fields.


Environmental protection and cost-effectiveness: With the improvement of environmental awareness, the application of silicone resins in the production of pressure-sensitive adhesives has also tended to be environmentally friendly and low-cost products.By optimizing the production process and formula design, the use of organic solvents can be reduced, production costs can be reduced, and the impact on the environment can be reduced at the same time.
