Film for sealing primary and secondary pollution sources in buildings, has adhesive layer adhering on metals, concrete, plastering or wood, and metal films including widths matched with diffusion depth of pollutant

摘要

The film has a weather-proof adhesive, and a sealing of diffused pollutants in masonry i.e. concrete, based on a diffusion depth (d) of pollutant. A film made of metal i.e. aluminum, includes a thickness of 50 to 200 micrometers. A metal film with a bothsided coating of thermoplastic includes a thickness of 20 to 80 micrometers. Another metal film with a one-sided, permanent adhesive layer includes a thickness of 0.5 to 4 mm. An adhesive layer adheres on metals, the concrete, plastering or wood. Widths of the metal films are matched with the diffusion depth. An independent claim is also included for a method for sealing primary and secondary pollutant sources in buildings.
