Abstract
A hot-melt adhesive composition comprises a mixture of silylated polymers, a tackifying resin and a catalyst, in specific contents, having self-adhesive properties after crosslinking to moisture. A self-adhesive article comprises a support layer and at least one self-adhesive layer obtained after crosslinking to the moisture in the adhesive composition according to the invention. The self-adhesive article can be used to bond low-energy substrates, in particular plastic substrates, notably thermoplastic substrates having low surface energy.
