How to distinguish the quality problems of colored tapes? Dongguan sealing glue wholesaler

Dongguan sealing glue wholesalers share with you: compared with the appearance of the tape, the glue is less, the color of the whole roll of doped tape is very dark, and the light transmittance of the tape is high after it is pulled. The color of the whole roll of good tape is not much different from the color of the strip after pulling it apart, because the good tape has a strong shielding property, and there is no superposition of colors. The most important thing is to see the thickness of the glue. If no glue is pulled apart or pulled apart in dots, there is a large amount of impurities in the glue, and the glue has no cohesion. Second, there is too much water and it has evaporated. At this time, the initial adhesion of the tape has dropped very much, and the feel can be distinguished. Apply the yellow tape to the object, the better the masking, the thicker the glue and the better the quality.
