Abstract
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.
Claims23
A contact layer comprising a solid filler component F and a thermoplastic polymer component P, wherein the amount of the solid filler component F is 10.0-90.0 wt.-% based on the total weight of the contact layer, and the solid filler component F comprises at least one mineral binder selected from hydraulic binders,
- wherein the contact layer comprises not more than 2.5 wt.-% of hydrated mineral binders, based on the total weight of the contact layer,
- wherein the thermoplastic polymer component P comprises at least one polymer selected from the group consisting of ethylene-vinyl acetate co-polymers (EVA), ethylene-acrylic ester copolymers, ethylene-α-olefin co-polymers, ethylene-propylene co-polymers, polypropylene (PP), polyethylene (PE), polyvinylchloride (PVC), polyethylene terephthalate (PET), polystyrene (PS), polyamides (PA), chlorosulfonated polyethylene (CSPE), ethylene propylene diene rubber (EPDM), and polyisobutylene (PIB), and mixtures thereof, and
