ABSTRACT:
The present invention relates to polyurethane fusion adhesives that are hardened by the action of moisture and which contain at least one reaction product from a component that contains NCO groups and an essentially linear hydroxypolyester, hydroxypolyether, and/or hydroxypolyetherester component. In addition, the present invention relates to a procedure for manufacturing a material that is permeable to water only in vapor form, this being in the form of a fiber material, in particular in the form of a web, which is joined to a polyurethane film, in which the fiber material is coated with a polyurethane material and subsequently the polyurethane material is hardened to form a water-vapor permeable film. The present invention also relates to a material that is permeable to water only in vapor form and which is in the form of a fiber material, in particular in the form of a web, that is bonded to a polyurethane film. According to the present invention, a fusion adhesive with a segmented hydroxypolyester or an hydroxypolyether or an hydroxypolyetherester component is used for this purpose as polyurethane material. The fusion adhesive according to the present invention can be applied directly or by a transfer technique to the fiber material and is hardened in only one step, by the action of moisture, to form a water-vapor permeable, but otherwise high quality water-proof membrane film.
