Humidity resistance

Moisture or even humidity can affect the performance of an adhesive, especially if applied under wet or very humid conditions. In this instance, the adhesive absorbs the humidity, which leads to reduced adhesion performance. This effect occurs especially with water-based acrylics, which should not be used under those conditions. In general an adhesive tape is humidity resistant when it resists contact with humid air or even water without negative effects on the adhesion properties.  Humidity can also damage paper liners and lead to ‘bubbles’ on the surface of the tape. All acrylics have a good humidity resistance and filmic liners are more dimensionally stable than paper ones. Read our guide on the correct storage of your adhesive tape
