tesa Double-Sided Adhesive Tape, Transparent

tesa® 64621 is a versatile, transparent double-sided adhesive tape with high initial tack for a wide range of mounting and securing applications.

Description

tesa® 64621 is a double-sided adhesive tape with a transparent PP film as the backing and a solvent-free synthetic rubber adhesive. It is covered with a silicone-coated release paper and, thanks to its special adhesive formulation, offers excellent initial tack. The tape is ideal for securing and fastening items, as well as for adding self-adhesive properties to decorative and packaging materials. It also reliably bonds fabrics, films, paper, and plastic materials. With good moisture resistance, moderate UV aging resistance, and very good fogging resistance, tesa® 64621 is the practical solution for many industrial and commercial applications.
