The main components of acrylic pressure-sensitive adhesive include acrylic monomers and crosslinking agents, while auxiliary components include plasticizers, stabilizers, fillers, etc.
1、 Main components
The main components of acrylic pressure-sensitive adhesive are acrylic monomers and crosslinking agents. Acrylic monomers are the main body of adhesives, and different types of acrylic monomers have different molecular weights, which affect the adhesion and peel strength of adhesives. The function of crosslinking agents is to form a network structure of monomer molecules, increase the viscosity and strength of adhesives, and improve their heat and chemical resistance.
2、 Auxiliary components
In addition to acrylic monomers and crosslinking agents, acrylic pressure-sensitive adhesives also include some auxiliary components. Plasticizers are substances that make it easier for monomer molecules to aggregate and form chain structures during reactions, increasing viscosity. Stabilizers are used to protect adhesives from external environmental influences during manufacturing and storage, ensuring their stable performance. The function of fillers is to fill the gaps in the adhesive, reduce costs, improve adhesion and heat resistance.
3、 Performance characteristics
Acrylic pressure-sensitive adhesive has the characteristics of strong viscosity, low peel strength, good heat resistance, and stable chemical properties, and can be widely used in fields such as labels, tapes, and adhesive paper.
4、 Summary
Acrylic pressure-sensitive adhesive, as an important industrial adhesive, consists of main components and auxiliary components. Acrylic monomers and crosslinking agents are the main components, while plasticizers, stabilizers, and fillers are auxiliary components. Acrylic pressure-sensitive adhesive has many excellent performance characteristics and is one of the indispensable industrial materials.
