The present invention is in the field of an improved adhesive composition, use of said composition and products comprising said composition. The adhesive composition may be a one component and a two component adhesive, each component typically comprising various ingredients. The present adhesives are water-based dispersions.

An adhesive composition containing a latex of a highly saturated nitrile rubber (A) which has ,-ethylenically unsaturated nitrile monomer units 10 to 55 wt %, conjugated diene monomer units 25 to 89 wt %, and ,-ethylenically unsaturated dicarboxylic acid monoester monomer units 1 to 20 wt % and has an iodine value of 120 or less and a polyvalent amine compound (B).

An adhesive material that provides fast and robust adhesion on wet surfaces, where the adhesion formed is detachable on-demand. The adhesive material is formed of one or more hydrophilic polymers or copolymers grafted with one or more amine coupling groups via a plurality of cleavable physical bonds and/or cleavable covalent bonds and one or more cross linkers. Application of the adhesive material on a wet surface causes the adhesive material to absorb liquid to thereby swell the adhesive material to form a layer of hydrogel, resulting in the formation of temporary crosslinks followed by covalent crosslinks with the surface. Introducing a triggering agent cleaves the cleavable physical bonds and/or cleavable covalent bonds to allow for non-traumatic detachment of the adhesive material from the surface.
