1. Product Overview
tesa® 61532 is a 50µm transparent double-sided PET tape designed with a differential adhesive system. One side uses a silicone adhesive for secure bonding to silicone-based substrates, while the other side features a modified acrylic adhesive for versatile adhesion across various materials. It combines reliable tack, good resistance to challenging environments, and efficient handling in converting processes.
2. Applications
Mounting on silicone or silicone-containing substrates
Fastening silicone rubber components (keypads, gaskets, rubber feet)
Mounting logos or decorative parts on UV-coated housings
