tesa® 4980
Double-sided smooth lamination filmic tape
Product description
tesa® 4980 is a transparent double-sided self-adhesive tape consisting of a PET backing and a tackified acrylic adhesive.
tesa® 4980 features especially:
- Good bonding strength to most common, smooth, even substrates
- Superior converting performance due to strong PET backing
- Initial repositioning in the assembly due to reduced immediate contact adhesion
