Pressure-sensitive adhesive composition

Pressure-sensitive adhesive compositions are composite materials made from a mixture of various ingredients used to prepare products such as tapes, labels, stickers, etc. These ingredients can include an adhesive base, viscosities, diluent, filler, additive, etc. The combination and proportion of each component will affect the performance, characteristics, and application range of the adhesive.

The following are the ingredients and effects of some common glue-sensitive adhesive compositions:

1. Adhesive matrix: usually adhesive polymers, such as acrylates, rubber, etc. The adhesive matrix provides the main adhesion properties and stickiness.
2. Viscosifier: Viscosifier can increase the adhesion and viscosity of the adhesive so that it is better attached to various surfaces.
3. 3. Diluent: Diluent can adjust the fluidity and viscosity of the adhesive, making it easier to handle and apply.
4. Fillers: Fillers can affect the characteristics of adhesives, such as strength, temperature resistance, chemical resistance, etc.
5. Additives: Additives can be used to adjust the performance of adhesives, such as improving weather resistance, water resistance, UV resistance, etc.
6. Active agent: Active agent can promote the polymerization reaction and help form the network structure of the adhesive.
7. Reaction AIDS: Some compositions need to be cured by specific reaction processes, and reaction AIDS can promote or control these reactions.
8. Solvent: In some adhesives, the solvent can be used to dissolve other ingredients together, and then evaporate after drying to make the adhesive cure.

Different types of pressure-sensitive adhesive compositions can be adjusted and optimized for specific application requirements. The preparation of these compositions requires experimentation and testing to determine the best formulation and to ensure that the prepared adhesives have the desired properties and characteristics for the particular application.
