Disclosed is a moisture switchable adhesive composition including a polymer and a switch initiator. The composition can be switched from a first liquid state to a second adhesive state by activation of the switch initiator. The composition has in the first liquid state a complex viscosity |&#x3b7;*| below 0.4 MPa s; and the composition has in the second adhesive state a second repeated peel force above 1 N/25 mm.

Disclosed is a composition including a polymer and a switch initiator. The composition can be switched from a first liquid state to a second adhesive state by activation of the switch initiator. The composition has in the first liquid state a complex viscosity |&#x3b7;*| below 0.4 MPa s; and the composition has in the second adhesive state a second repeated peel force above 1 N/25 mm.

Composition comprising a polymer and a switch initiator

Moisture-curable adhesive compositions, their preparation and use are disclosed herein. The moisture-curable adhesive compositions include one or more reactive polymers, such as reactive silicone polymers, one or more adhesive components, such as a silicone pressure sensitive polymer(s) (PSAs), a cross-linker and a catalyst. Typically, the reactive silicone polymer or polymers are hydroxyl terminated polydimethylsiloxanes (PDMS) having at least two hydroxyl functionalities associated with the polymer(s).

Adhesive composition

A photoinitiator is provided which incorporates a camphorquinone photoinitiator moiety.
