A sealing device including a waterproofing membrane, a sealant layer covering a portion of the second primary exterior surface of the waterproofing membrane, and an adhesive layer covering a portion of the second primary exterior surface of the waterproofing membrane, wherein the sealant layer is composed of an adhesive sealant composition comprising 1-40 wt.-% of at least one elastomer, 10-60 wt.-% of at least one at 25° C. liquid polyolefin resin, and 5-65 wt.-% of at least one inert mineral filler. Further, a method for producing a sealing device, to a method for waterproofing a substrate, and to a waterproofed substrate.

Self-adhering sealing device with an adhesive layer arrangement

A sealing device including a waterproofing layer including at least one thermoplastic elastomer P1 and an outer layer of non-woven fabric directly adhered to at least portion of the second major surface of the waterproofing layer, wherein the outer layer of non-woven fabric including at least one polymer P2. Further, a method for producing a sealing device, to the use of a layer of non-woven fabric including or essentially consisting of polypropylene fibers for reducing blocking of a waterproofing layer including at least one propylene-based thermoplastic elastomer, and to a method for covering a roof substrate using the sealing devices of the present invention.

Sealing device with a weldable fiber-based layer

A sealing device includes a waterproofing membrane, an adhesive sealant layer, and optionally a release liner, wherein the adhesive sealant layer includes at least one elastomer, at least one at 25° C. liquid polyolefin resin, and at least one inert mineral filler. An adhesive sealant composition is used to form the adhesive sealant layer. The sealant device may be used to waterproof a substrate and provide a fully-adhered roof system. The adhesive sealant composition may be used to provide a self-healing roofing membrane.

Self-adhering sealing device with an adhesive sealant layer

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.

Method for adhesively bonding rubber-based thermoplastic substrates

A composition including a melt blend of at least one thermoplastic elastomer (TPE) and at least one non-crosslinked elastomer and optionally at least one catalyst for catalyzing chain extension and/or crosslinking and/or coupling reactions of the at least one non-crosslinked elastomer. Further, a method for producing a polymer composition, to a shaped article including a substrate layer composed of the composition, to a method producing a shaped article, and to a method for covering a roof using the shaped articles.

Polymer composition with improved mechanical properties

A sealing device including a waterproofing membrane, a sealant layer covering at least a portion of the second primary exterior surface of the waterproofing membrane and an adhesive layer covering a portion of the outer major surface of the sealant layer facing away from the second primary exterior surface of the waterproofing membrane, wherein the sealant layer is composed of an adhesive sealant composition comprising at least one elastomer, at least one at 25&#xb0; C. liquid polyolefin resin, and at least one inert mineral filler. A method produces a sealing device, a method waterproofs a substrate, and a waterproofed substrate.
