Abstract (en)
[origin: EP0412889A1] Prefabricated acrylic waterproof material made as a multilayer sheet, comprising a layer of textile backing, a layer of a foam made from an acrylic polymeric material and a layer of a binder made from an acrylic polymer material, characterised in that each layer is bound to at least one of the other two layers in such a way that the foam layer is always in contact with the textile backing layer, the thicknesses of the various layers of the multilayer sheet correspond to the surface densities of the said layers, ranging from 30 to 300 g/m<2> for the textile backing layer, from 10 to 100 g/m<2> for the foam layer and from 50 to 2000 g/m<2> for the binder layer.
