FAQ
Q
Why does pressure sensitive adhesive tape show different adhesiveness in winter and summer?
A
Because the glass transition temperature of pressure-sensitive adhesive is about-20 °C to-50 °C, when the room temperature is lower, the closer the adhesive tape is to the glassy state, which visually shows that the adhesive surface will become "hard" and the initial adhesion and peeling will decrease.
Q
Why does the viscosity of adhesive tape decrease during storage?
A
1.Moisture in the air will reduce the viscosity of the adhesive tape;
2. The silicon transfer of the release material will reduce the adhesion of the tape.
