1. Product Overview
tesa® 68542 is a transparent, double-sided PET filmic tape with a tackified acrylic adhesive. With a thickness of only 50 µm, it provides excellent handling during converting processes while maintaining strong adhesion. The tape demonstrates reliable performance under demanding environmental conditions, including very good resistance to UV, humidity, and softeners. It is engineered for high adhesion levels and stable bonding in industrial applications.
2. Applications
General mounting in electronics
Laminating processes for electronic components
Suitable for bonding where thin, transparent adhesive layers are required
