How To Judge The Gaffer Grip Tape's Adhesive Force?

The adhesive force of the gaffer grip tape determines the quality of the tape. The greater the adhesive force, the better the quality of the tape, and vice versa.

The adhesive force of the gaffer tape simply refers to the degree of adhesion of the tape and the object. The adhesive force of the gaffer grip tape is generally composed of two parts: the initial adhesion and the holding adhesion. The common method to check the adhesiveness of girp tape is the steel ball inspection method.

Factors affecting the adhesive force of grip tape

1. Adhesive force of grip tape refers to the connection force between the adhesive and the surface of the sticky object. Its generation not only depends on the surface structure and state of the adhesive and the adherend, but also is closely related to the process conditions of the bonding process. The adhesive force of the tape is the force or bonding force between the adhesive and the adherend at the interface, including mechanical embedding force, intermolecular force and chemical bonding force.

2. Mechanical interlocking force is the bonding force produced by the inlay after the adhesive molecules diffuse and penetrate into the surface pores of the adherend and solidify. Although this mechanical fitting force is small, it cannot be ignored.

3. Intermolecular force is the force that attracts molecules between the adhesive and the adherend, including van der Waals force and hydrogen bond, and its action distance is 0.3~0.5nm.

4. The chemical bond force is the chemical bond that can be formed between the adhesive and the surface of the adherend. There are covalent bonds, coordinate bonds, ionic bonds, metal bonds, etc. The bond energy is much higher than the intermolecular force, and the chemical bond is very strong. Strong, has a great influence on bonding strength.

5. The polarity of the adhesive is too high, and sometimes it will seriously hinder the wetting process and reduce the adhesion.

The adhesive force of the gaffer grip tape is the toughness and the strength of the adhesive tape, which determines the quality of the tape.
