The present disclosure provides a product for preventing the deterioration of an adhesive layer and a method for manufacturing the product. The product comprises a first product housing, a second product housing, an adhesive layer, and a protective layer. The second product housing is opposite to the first product housing. A gap exists between the second product housing and the first product housing. The adhesive layer is disposed in the gap between the first product housing and the second product housing, adhering to the first product housing and the second product housing. The protective layer is disposed on the adhesive layer. The protective layer is disposed in the gap, covering the outer surface of the adhesive layer. The protective layer bonds and cross-links to the adhesive layer chemically.

Described herein is a pressure sensitive adhesive comprising a high molecular weight fluorinated polymer having a Tg less than about 0 C. and a number average molecular weight greater than about 20 kilograms/mole; and a low molecular weight fluorinated polymer derived from an ethylenically unsaturated fluorinated monomer, wherein the low molecular weight fluorinated polymer has a Tg greater than about 15 C. and a number average molecular weight less than about 18 kilograms/mole. Also described herein are articles comprising the pressure sensitive adhesive composition.
