tesa® 61562 Optically Clear Adhesive
25µm transfer transparent barrier tape
Product description
tesa® 61562 is a transparent, thin transfer tape that ensures good encapsulation for oxygen and especially water vapour sensitive devices. This is realized by the specialty pressure sensitive adhesive (PSA). This special adhesive ensures very good device stability even at high temperature.
tesa® 61562 does not require curing and therefore enables fast processing.
Consequently it does not exhibit cure shrinkage and thus provides permanent adhesion between different device layers and good encapsulation for sensitive parts. The product enables the design of flexible devices.
tesa® 61562 features especially:
- High barrier against oxygen and water vapor
- High temperature stability
- Bubble-free performance at demanding test conditions
