Title:

Use of the polyolefin closure film covered with the nonresponsive hot melt adhesive for closure

Document Type and Number:

Japanese Patent JP5976007

Kind Code:

B2

Abstract:

Sealing a building and civil engineering works or building construction comprises: (a) coating a flexible polyolefin sealing film (1) with a non-reactive hot-melt adhesive composition (2) to form a hot-melt adhesive-coated polyolefin sealing film, which is tack-free at 25[deg] C; (b) placing the hot-melt adhesive-coated polyolefin sealing film onto the surface (4) of a building (5) of the civil engineering works or building construction; (c) supplying heat under melting of the non-reactive hot-melt adhesive composition; and (d) cooling the non-reactive hot-melt adhesive composition. Sealing a building and civil engineering works or building construction comprises: (a) coating a flexible polyolefin sealing film (1) with a non-reactive hot-melt adhesive composition (2) to form a hot-melt adhesive-coated polyolefin sealing film, which is tack-free at 25[deg] C; (b) placing the hot-melt adhesive-coated polyolefin sealing film onto the surface (4) of a building (5) of the civil engineering works or building construction; (c) supplying heat under melting of the non-reactive hot-melt adhesive composition; and (d) cooling the non-reactive hot-melt adhesive composition to form an adhesive bond between the flexible polyolefin sealing film and the surface of the structure, where the non-reactive hot-melt adhesive composition is free of epoxy resin. An independent claim is also included for a layer composite body (8) comprising (i) layer of a polyolefin film sealing foil, (ii) layer of a hot-melt adhesive composition and (iii) building and civil engineering works or building construction, where the layer of hot-melt adhesive composition is arranged between the layer of polyolefin film and sealing foil of the building and civil engineering works or building construction.
