Main Features of Tape






Initial adhesion: 


Describe the performance of the adhesive first contact with the surface。

In the smallest pressure and the shortest contact time to take effect。

Irrelevant to the adhesive force which is generated after pressure

Strong initial adhesion can support adhesion to rough surfaces


Test Method: ball rolling test method (initial viscosity)





Bonding force: 


Describe the attractiveness of the adhesive and the object surface.

It is a very important performance of tape.

Applying pressure to the bonding surface creates the bonding force.

Usually increase by 15% to 150% within the first day.

Depond on the glue, pasted object, pressure, time and environmental conditions。

Describe the internal strength of the adhesive

Mainly determines the retention force in the application

If external forces act parallel to the bonding surface, this application is related to cohesion
