  • Patent number: 11987925
    Abstract: The invention relates to a waterproof membrane for building applications comprising at least one support carrier and at least one layer of a cross-linked coating composition comprising at least one polyurethane. The invention also relates to a waterproof membrane comprising at least one support carrier and at least one layer of a cross-linked coating composition comprising at least one polyurethane, an optional pre-coating layer to facilitate the manufacturing process, and to join the support carrier with the cross-linked coating composition in the most optimal and durable manner to achieve good surface appearance and chemical bonding between reinforcing carrier and crosslinked polyurethane coating. The waterproof membrane can be prepared and installed with lower cost in comparison to current flat roof waterproofing systems based on liquid two-component polyurethane systems.

  • Publication number: 20140045397
    Abstract: A process for manufacturing a nonwoven barrier fabric having a first face and an second opposite face, with the steps of applying a primer composition by vapor or aerosol deposition, to the first face of the fabric to form a layer of the primer composition, wherein the primer composition is essentially free of fluorinated compound, and applying a barrier composition comprising at least one unsaturated fluorinated compound by vapor or aerosol deposition to the layer of primer composition to form at least one, and preferably from one (1) to four (4), more preferably two (2) or three (2), layers of the barrier composition on the layer of primer composition and a fabric obtainable according to the process.

  • Publication number: 20090158683
    Abstract: A multiple sheet building wrap for wrapping the structural components of a building in order to protect the underlying structural components and optional building sheathing from moisture is provided. The building wrap is particularly useful under facades such as wet applied stucco or engineered stone, demonstrating good drainage of liquid water and moisture vapor permeability. The building wrap is a composite of a water resistive barrier, a three-dimensional mesh layer and a porous intervening layer which acts to filter the stucco as it is applied. An exterior wall construction incorporating such building wrap is also provided.
