Adhesion characteristics of pressure-sensitive adhesive

The adhesion characteristics of pressure-sensitive adhesive refer to the fact that the pressure-sensitive adhesive can firmly adhere to the surface of the object when it contacts the surface of the object and can form a uniform bonding layer under the action of a certain external force.

This property allows pressure-sensitive adhesives to be widely used in various fields, such as packaging, labeling, electronics, automotive, construction, etc.

The adhesion characteristics of pressure-sensitive adhesive mainly include adhesion force, adhesion range, and adhesion stability. Among them, the adhesive force refers to the adhesive force produced by the pressure-sensitive adhesive when it contacts the surface of the object; The adhesion range refers to the surface range of the object that the pressure-sensitive adhesive can adhere to; Adhesion stability refers to the ability of pressure sensitive adhesives to maintain stable adhesion during long-term use.

For example, the sticky notes we use in daily life use the adhesive properties of pressure-sensitive adhesive to achieve the function of paste. In the manufacturing process of Post-it notes, it is necessary to use a special pressure-sensitive adhesive, which can create a strong adhesion when it contacts the surface of the object so that the Post-it note will not leave a residue after being torn off. In addition, pressure-sensitive adhesives can also be widely used in construction, electronics, automotive and other industrial fields, for the manufacture of labels, tapes, sealants, and other products.
