tesa® 4914
Double-sided non-woven tape with differential adhesive
Product description
tesa® 4914 is a translucent double-sided self-adhesive tape consisting of a non-woven backing and a tackified acrylic adhesive with lower coating weight on the open side.
tesa® 4914 features especially:
- Open side: lower adhesion level
- Easier removal while tearing the bond apart from the original surface even after exposure to demanding environmental conditions
- Covered side: higher adhesion level
- Foamed adhesive coating with high initial tack
- Excellent performance on rough surfaces
