Cross-linking method and associated device

Self-adhesive article comprising at least a substrate and an adhesive layer, wherein the coating weight of said adhesive layer is between 600 and 1500 g/m2, wherein the adhesive layer was applied in one step, said adhesive layer being a cured adhesive composition comprising a silyl-containing polymer, a tackifying resin and a catalyst, and

• wherein the self-adhesive article is obtained by a process comprising:
• a) conditioning an adhesive composition comprising at least a silyl-containing polymer, a tackifying resin and a catalyst, at a temperature of between 20 and 160° C.;
• b) coating in a single step the adhesive composition onto:
• b1) at least a part of the substrate;
• or
• b2) onto a non-sticking support;
• c) submitting the article obtained at step b) to a temperature between 20 and 200° C. and to a humidity level characterized by an atmosphere in which between 5 and 90% of the molecules are water molecules to obtain the adhesive layer;
• and
• if b2) is chosen, then
• d) depositing the substrate onto the adhesive composition before step c) or onto the adhesive layer after step c),
• wherein the self-adhesive article has adhesion to a surface characterized by a shear resistance, determined at ambient temperature and under 1 kg, of higher than 1 day.
