Abstract: A method for adhesively bonding two substrates by means of a moisture-curable adhesive composition, wherein at least one of the substrates includes at least 40 wt.-% of a mixture, said mixture consisting of: between 15 and 99 wt.-% of at least one thermoplastic polymer; between 1 and 85 wt.-% of at least one elastomer; and wherein the moisture-curable adhesive composition includes: at least one polymer containing silane groups; between 10 and 40 wt.-% of at least one polymeric plasticizer; between 0.1 and 5 wt.-% of at least one amino-functional alkoxysilane; between 0 and 5 wt.-% of at least one C1-C12-alkyl-functional alkoxysilane. The method yields adhesively bonded substrates without the requirements of using migrating plasticizers and pre-treating of the substrates.

Abstract: A thermoplastic composition including a thermoplastic polymer component and at least one elastomer, wherein the thermoplastic polymer component comprises at least one propylene copolymer having a propylene content of at least 60 wt.-% and at least one ethylene copolymer having an ethylene content of at least 50 wt.-%. The invention is also directed to a sealing device comprising a waterproofing layer obtained by using the thermoplastic composition, to a method for producing a sealing device, to a method for waterproofing a substrate, and to a method for bonding a first substrate to a second substrate.
