Why Does Double Sided Tape Not Sticky

- Jul 23, 2019-

1. The double-sided tape sticks to the surface which is too smooth, and the phenomenon of tape failure is easy to occur, mainly because the adhesive molecules of the double-sided tape itself directly form a bond with the adhered object molecules, when the adherend molecules adhere and adhere. When the agent molecules cannot be connected, the tape failure phenomenon occurs.   

2. The ambient temperature has a great influence on the tape during use. When the temperature difference between the tape and the ambient temperature is too large, the double-sided tape will directly fail. Mainly due to the temperature, the molecular activity of the adhesive is reduced, and even the structure of the molecule is changed. Therefore, the choice of suitable double-sided tape needs to be determined according to the ambient temperature of the tape used. Ordinary tape temperature is between 10 ° C and 38 ° C. The double-sided tape commonly used in industry is 0 ° C - 80 ° C in the working environment.   

3. The impurities or particles on the surface of the adherend will also reduce the fit of the double-sided tape.   

4, Most tapes can not be wet, especially water-soluble tape, the performance of the tape can not be used normally. There is also a special working environment in the industry, which is inevitably in contact with water. At this time, we should choose a special waterproof tape. When choosing a tape, look at the adhesive. The waterproof tape is glued with solvent-based glue, epoxy glue and For polyurethanes, the glue does not react with water solvents or chemically.  

5, After the shelf life.
