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
