US005516581A teaches a method to make a stretchable de-bondable tape, where the tape carrier is a highly extensible film (or others) with low elastic recovery (preferably less than 30%). This property could be useful for the indication of tampering and ensureing single use in certain applications.

Literature study-F containing UVR formulation
US 8,193,259 B2, with title of “UV-CURABLE PRESSURE-SENSITIVE ADHESIVE COMPOSITION WITH A FLUORINATED ACRYLIC BINDER RESINAND PRESSURE-SENSITIVE ADHESIVE FILM USING THE SAME”, teaches a way to formulate UV Release (UVR) adhesive formulation where a fluorinated acrylic segment is introduced to the main chain to deliver excellent pick-up performances after UV illumination.

Due to better refractive index matching between optical film and OCA, optically clear adhesive, compared to only air gap, OCA dramatically enhances display performances; there it have been broadly applied in the displays, solar cells, automobiles, buildings, et. al. In addition to provide suitable adhesion, it is also required to be optically transparent, colorless, weathering/aging resistant (no yellowing, no bubbles), and sometimes it requires to able to sustain high temperature, dissipate stress and more as required by specific applications.

Some nice videos from DISCO company website. Always good to understand the process in order to select or recommend most suitable materials for the best results.

In the semiconductor processing, e.g. dicing, grinding, wafers or similar objects need to be held with enough adhesion; after the process completed, the finished parts need to be peeled off easily from the holder. UV release tapes (UVR) are quite suitable for such applications.

Thermal Release tape or thermal debonding tape is a special functional tape which functions as a regular tape sticking to a substrate or bonding two surfaces together under certain temperature, T(stable); however it debonds at another temperature, typically higher temperature (e.g. 15C higher T(debond)), as shown in Figure 1.
