FAQ

Q

WHY DOES PRESSURE-SENSITIVE TAPES SHOW DIFFERENT STICKINESS IN WINTER AND SUMMER?

A

As the glass transition temperature of pressure-sensitive tapes is -20℃ to -50℃, when the room temperature is lower, the tape is closer to the glass state, which shows that the adhesive surface will become "hard", and the initial adhesion and peeling will decrease.


Q

WHY DOES THE ADHESIVENESS DECREASE DURING TAOE STORAGE?

A

1. The moisture in the air will reduce the adhesiveness of the tape;

2. Silicon transfer of the release material will reduce the adhesiveness of the tape.
