The adhesion of pressure-sensitive adhesives is improved by incorporating specific additives

By mixing specific additives, the adhesion ability of the pressure-sensitive adhesive can be effectively improved to meet the needs of different applications. These additives can affect the adhesive properties, durability, temperature stability, and other characteristics.

Here are some common additives that can be used to improve the performance of pressure-sensitive adhesives:

1. Viscosifier (thickener): Viscosifier can increase the viscosity of the adhesive, thereby improving the adhesion and viscosity. This is useful for applications that require stronger adhesion.
2. Antioxidants: Antioxidants can help prevent oxidative degradation of adhesives under prolonged exposure to oxygen and heat, thereby extending the service life of adhesives.
3. Fillers: Fillers (such as particulate or fibrous materials) can change the structure of the adhesive and increase its shear resistance and strength.
4. Viscosity regulator: The viscosity regulator can adjust the viscosity of the adhesive so that it can adapt to different application methods and requirements.
5. Adhesion enhancer: These additives can enhance the adhesion between the adhesive and different surfaces and improve the adhesion performance.
6. Temperature improvers: For applications that need to be used in high or low-temperature environments, adding temperature improvers can improve the temperature resistance of adhesives.
7. Preservatives: Preservatives can protect adhesives from microbial contamination and biodegradation, extending the stability of the product.
8. Fillers: Adding tiny fillers can adjust the properties of adhesives, such as increasing adhesion, durability, etc.
9. Anti-aging agent: Anti-aging agents can slow down the aging and degradation of adhesives caused by light, heat, and other factors.
10. Environmental protection additives: Environmental protection additives can make adhesives more environmentally friendly, such as the use of degradable materials or low volatile organic compounds.

The choice of additives should be determined according to the specific application and needs of the adhesive. In the use of additives, it is necessary to carefully consider their compatibility, impact, and possible effects to ensure that the performance of the adhesive is effectively improved.
