Use of an adhesive composition to provide a bonding in a wet environment

1. A method comprising bonding at least one surface covered with a layer of aqueous medium of 1 μm or more to at least one article, said article comprising at least one substrate and an adhesive layer, wherein said adhesive layer is obtained by curing an adhesive composition comprising:

a) from 20 to 85% by weight of at least one silyl-containing polymer selected from:

i) a silyl-containing polyether having from 1.9 to 2.1 silyl functions per molecule,

ii) a silyl-containing polyurethane,

iii) a silyl-containing polyurethane having polyurethane-polyether and polyurethane-polyester blocks,

and mixtures thereof,

b) from 25 to 80% by weight of at least one compatible tackifying resin and

c) from 0.01 to 3% by weight of at least one catalyst,

d) less than 5% by weight of solvent,

based on the total weight of the adhesive composition.

2. The method according to claim 1 , wherein, at least 90% by weight of the silyl-containing polymer(s) are silyl-containing polyethers having from 1.9 to 2.1 silyl functions per molecule, silyl-containing polyurethanes, silyl-containing polyurethanes having polyurethane-polyether and polyurethane-polyester blocks, or mixtures thereof.

3. The method according to claim 1 , wherein the tackifying resin is phenol modified terpene resins, hydrocarbon resins, rosin ester resins, acrylic resins or mixtures thereof.

4. The method according to claim 1 , wherein the substrate is a protective non-sticking layer.

5. The method according to claim 4 , wherein the substrate is a siliconized film.

6. The method according to claim 1 , wherein the aqueous medium is water or body fluids.

7. The method according to claim 6 , wherein the aqueous medium is sea water, rain water, sweat, saliva, blood, urine, feces or lymphatic film.

8. The method according to claim 1 , wherein the surface covered with a layer of aqueous medium of 1 μm or more is a skin surface, a bathroom or kitchen equipment surface, a piping, a pipe, an aquatic article, a boat hull, a roof, a bridge, or a wall covering.

9. The method according to claim 1 , comprising repairing objects, and/or preventing and/or repairing leaks, and/or reinforcing a surface of an object, and/or creating a multilayer article, and/or superposing layers in an adhesive manner.

10. The method according to claim 1 , said method comprising:

a) removing the protective non-sticking layer when said layer is present;

b) applying the article onto the surface; and

c) applying a pressure onto the article.

11. The method according to claim 10 , wherein at least one of a), b) or c) is carried out under water.

12. The method according to claim 11 , carried out under sea water.

13. The method according to claim 10 , wherein the surface is a skin surface, a bathroom or kitchen equipment surface, a piping, a pipe, an aquatic article, a boat hull, a roof, a bridge, or a wall covering.

14. A method of repairing objects, and/or preventing and/or repairing leaks, and/or reinforcing a surface of an object, and/or creating a multilayer article, and/or superposing layers in an adhesive manner, wherein it includes a method according to claim 10 .

15. The method according to claim 10 , wherein applying the pressure onto the article substantially removes any water and/or air molecules which are trapped between the surface and the adhesive layer of the article.

16. The method according to claim 10 , wherein the bonding. has a peel strength which does not decrease with the passage of time.

17. The method according to claim 16 , wherein the bonding has a peel strength that increases with the passage of time.
