Moisture switchable adhesive composition comprising a polymer and a switch initiator

A moisture switchable adhesive composition comprising an unreactive silicone polymer and a switch initiator, wherein the composition can be switched from a liquid state to an adhesive state by exposure to moisture;

• the composition
• having in the liquid state a complex viscosity |η*| below 0.4 MPa s (mega Pascal second, i.e., MPa·s);
• and
• having in the adhesive state a higher complex viscosity |η*| than the complex viscosity |η*| of the liquid state, and having in the adhesive state a second repeated peel force above 1 N/25 mm;
• wherein the switch initiator comprises a reactive silicone polymer, a catalyst, and a crosslinker, and wherein the reactive silicone polymer together with the catalyst and the crosslinker react to form a crosslinked polymer network upon exposure to moisture, wherein the composition comprises hydrocolloid in an amount of 1-60% (w/w) of the composition.
