Abstract: Pressure-sensitive adhesive product in the form of one or more two-component adhesive laminates comprises a peelable coating cover on a two-component adhesive. The coating is formed of first region (2) and second region (3). The first region contains a first component of the two-component pressure-sensitive adhesive. The first component comprises at least one compound with first functional group. The second region contains a second component of the two-component pressure-sensitive adhesive containing at least one compound having second functional group. Pressure-sensitive adhesive product in the form of one or more two-component adhesive laminates comprises a peelable coating cover on a two-component adhesive. The coating is formed of at least first region (2) and at least second region (3). The first region contains a first component of the two-component pressure-sensitive adhesive. The first component comprises at least one compound with first functional group. The second region contains a second component of the two-component pressure-sensitive adhesive containing at least one compound having second functional group. The first and second functional groups are in contact with one another and may react with each other to cure the coating. The first and second regions are arranged on a single adhesive laminate or on two separate adhesive laminates. Independent claims are also included for bonding a first substrate to a second substrate, comprising either: providing the pressure-sensitive adhesive product, folding the adhesive laminate along the predetermined breaking point (4), so that the first and the second region of the coating with the two-component adhesive contact each other and initiating the curing of the two-component adhesive, separating a part of the covering material (1) in the predetermined breaking point, so that a portion of the coating is at least partially exposed to the two-component adhesive, connecting the exposed covering portion to the first substrate, removing the remaining part of the covering and connecting the separated remaining portion of the covering portion to the second substrate; or providing the pressure-sensitive adhesive product, where the first and second regions of the coatings are arranged on two separate adhesive laminates, removing a tackiness component having adhesive laminate containing at least a part of the covering from the first region so that the coating is at least partially exposed to the two-component adhesive, connecting the exposed covering portion to the first substrate, subsequently, connecting the first adhesive laminate to the second adhesive laminate so that the first and the second region of the coating with the two-component adhesive contact each other, initiating the curing of the two-component adhesive and then connecting the second adhesive laminate with the second substrate, and connecting the first component comprising a pressure-sensitive adhesion-containing laminate to the second adhesive laminate followed by separating the covering of the first adhesive laminate connected to the first substrate and the second adhesive laminate to the second substrate.
