A contact layer used in waterproofing and roofing applications. The contact layer includes a solid filler component F and a thermoplastic polymer component P. Also directed to a method for producing the contact layer, to a method for binding two substrates to each other, to a method for waterproofing a substrate, to a waterproofed structure, to a method for sealing a surface against water penetration, to a sealed construction for sealing a substrate against water penetration and to use of the contact layer as waterproofing membrane.

Contact layer with a solid filler component

The present invention relates to a sealing device () which comprises a barrier layer () with a thermoplastic polymer P1, and an adhesive layer () with at least one ethylene-vinyl acetate copolymer (EVA) P2 and azo-dicarbonamide A, and which is suitable for sealing bases in the building sector. The invention further relates to a method for sealing said bases. The method according to the invention allows structures of civil engineering to be sealed rapidly and efficiently and ensures good adhesion of the sealing device on the base.

Sealing device with improved adhesion

The present invention relates to a sealing device () comprising a barrier layer () and an adhesive layer (), and which is suitable for sealing bases in the building sector. The adhesive layer comprises a polymer P2, the polymer P2 being polyethylene (PE), polypropylene (PP) or a copolymer of ethylene and propylene, and a polyolefin-based polymer P3, the polymer P3 having at least one functional group which is selected from the group consisting of carboxylic acids, OH-groups, anhydrides, acetates and glycidyl methacrylate, and azo-dicarbonamide A. The invention further relates to a method for sealing the said bases. The method according to the invention allows structures of civil engineering to be sealed rapidly and efficiently and ensures good adhesion of the sealing device on the base.
