摘要:
The invention comprises a method. The method comprises applying a quantity of an aqueous dispersion of thermoplastic polymer particles to a primary backing and loop backs of a tufted carpet or a tufted synthetic turf, wherein the thermoplastic particles have an average particle size less than 1,000 microns. The method also comprises heating the aqueous dispersion to a temperature sufficient to remove water therefrom, and heating the thermoplastic particles on the primary backing and loop backs to a temperature at or above the melting temperature of the thermoplastic particles. The method further comprises allowing the heated thermoplastic polymer particles to cool below their melting temperature whereby the loop backs are adhered to the primary backing.
摘要:
The present subject matter provides a shrink film free of silicon-containing material, fluorine-containing material, and solvent-formed seams. The shrink film utilizes a water soluble layer covering an adhesive layer. The water soluble layer is in dry form and non-tacky, allowing processing of the shrink film subsequent to adhesive application to the shrink film. When the water soluble layer is dissolved, the adhesive layer is exposed and is capable of forming a permanent bond. The adhesive can be used to form a seam in the film and/or can be used to form a bond between the film and a substrate. The water soluble layer facilitates removal of an optional release liner from the adhesive. A substrate with the shrink film attached thereto and a related method of attaching a heat shrinkable film to a substrate are also disclosed.

A wallboard panel is provided, including a sheet of face paper, a first layer of gypsum composition having a first density, a web of mesh associated with the first layer of gypsum composition, a second layer of gypsum composition having a second density, the second density being lower than the first density, and a layer of backing paper. An associated method includes providing a sheet of face paper and laying same upon a moving conveyor belt, applying a first layer of gypsum composition slurry upon the sheet of face paper, applying a web of mesh upon the first layer of gypsum composition slurry, applying a second layer of gypsum composition slurry upon the web of mesh, and applying a sheet of backing paper upon the second layer of gypsum composition slurry.

Disclosed herein are sealing solutions for sealing water-soluble films, in particular aqueous mixtures including one or more polymeric solvents such as polyols. Aqueous sealing solutions including a relatively dilute solvent for one or more polymeric components of the water-soluble film (e.g., water-soluble polymeric components thereof, such as polyvinyl alcohol (PVOH)) can exhibit one or more benefits, including a reduction in dissolution of the film by the sealing solution and an increase in seal strength. Also disclosed are sealed articles formed with the sealing solutions, for example water-soluble packets containing various liquid or solid compositions.
摘要:
A method for adhesively bonding shaped elements made from wood-based materials to flexible film substrates, in which i) the side that is to be bonded is mechanically processed, ii) a reactive one- or two-component polyurethane adhesive is applied to the center regions of this side, iii) an aqueous adhesive based on EVA, PVAc, PVOH is applied at least to the outer region of this side, and iv) this side is bonded to a flexible substrate as an edge coating.
摘要:
A polyurethane dispersion is obtained by aqueously dispersing an aqueous polyurethane resin obtained by reaction of an isocyanate group-terminated urethane prepolymer with a chain extender. The isocyanate group-terminated urethane prepolymer contains an adhesive urethane prepolymer for imparting adhesion and a gas-barrier urethane prepolymer for imparting gas barrier properties.

“The present invention relates to the use of an encapsulated adhesion promoter in an effective amount in an aqueous adhesive joint, said aqueous adhesive joint being intended to bond a surface of a first substrate (S1) to a surface of a second substrate (S2), at least one of said two substrates comprising a material (TPE-PA) comprising at least one thermoplastic elastomer (TPE) and/or at least one polyamide (PA), said adhesion promoter (P) comprising at least one organic molecule having at least one isocyanate function blocked by encapsulation of said organic molecule.”
摘要:
A four-layer film for packaging, including blister packaging, is described. Layer 1 may be a rigid film, such as a polyvinyl chloride (PVC) or polyester. Layer 2 may be a moisture barrier, such as polychlorotrifluoroethylene (PCTFE). Layer 3 may be an oxygen barrier, such as a co-extruded film having a polyethylene (PE) layer, an EVOH layer, and a second PE layer. Layer 4 may be a relatively thin layer of a rigid film, such as a PVC or polyester. In this arrangement, Layer 2 may protect the contents of the package from external or atmospheric moisture. Layer 2 may also protect Layer 3 from atmospheric moisture, thereby helping to preserve the effectiveness of Layer 3 as an oxygen barrier.
