The instant invention relates to primary coating compositions that comprises a cationic polysaccharide, to be applied on a hydrophobic surface before a subsequent application of a polar or water based coating composition, such a as a paint or an adhesive.

A partition is disclosed having a two sided lamination thereon for protecting products in containers and bins.

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.

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.

An aqueous dispersion containing polylactic acid as a dispersoid and polyvinyl alcohols as a dispersant is improved to impart more excellent heat-sealing properties and water-resisting properties to a resulting polylactic acid film. An aqueous dispersion for forming a film containing 3 g/m.sup.2 (dry weight) or more of polylactic acid to a substrate, the aqueous dispersion including polylactic acid, polyvinyl alcohols, and water, in which the polyvinyl alcohols have an average saponification degree of 60.0 to 82.0 mol %, and a blending ratio (mass ratio) of the polylactic acid and the polyvinyl alcohols is 98/2 to 90/10.

Provided is a PSA sheet having a PSA layer. The PSA layer includes a layer A forming at least one surface thereof. The PSA sheet has an adhesive strength N0 of 2.0 N/10 mm or greater, after one day at room temperature following application of the layer A side to a surface of an alkaline float glass plate as an adherend having a contact angle of 5-10 with distilled water; has an N1 to N0 reduction rate of 30% or lower, wherein N1 is a water-resistant adhesive strength measured after stored at room temperature for one day, immersed in water for 30 minutes, taken out from the water and then residual water is wiped off, and has an N2 to N0 reduction rate of 40% or higher, wherein N2 is a water-peel strength measured after stored at room temperature for one day, 20 L distilled water is dropped onto the adherend and is allowed to enter a PSA layer/adherend interfacial edge. N2 is measured at a tensile speed of 300 mm/min at a peel angle of 180.

An optical film includes: a polarization layer; a first phase retardation layer having an optic axis at an angle in a range from about 17 degrees to about 27 degrees or from about 27 degrees to about 17 degrees with respect to a transmission axis of the polarization layer; and a second phase retardation layer having an optic axis at an angle in a range from about 85 degrees to about 95 degrees with respect to the transmission axis of the polarization layer. The polarization layer, the first phase retardation layer, and the second phase retardation layer are deposited in sequence, the first phase retardation layer is a half-wave plate, the second phase retardation layer is a quarter-wave plate, and out-of-plane retardation values of the first phase retardation layer and the second phase retardation layer for incident light having the standard wavelength have opposite signs.

According to the present disclosure, a method for securing a threaded fastener in a threaded hole includes directly applying a locking compound to at least a portion of threads to be mated on either the threaded fastener or the threaded hole. The locking compound includes a substantially pure, non-chromated aluminum pigmented compound suspended in a water-based inorganic binder with temperature resistance in excess of 900 degrees Fahrenheit (about 482 degrees Celsius). The threaded fastener is threaded into the threaded hole after applying the locking compound on the threads to be mated.

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.

The present invention relates generally to a protective wrap and a protective envelope or pouch made therefrom, as well as the apparatus and process for forming such wraps and envelopes. Water-based heat-expandable adhesives (WBHEA) which include a plurality of heat-expandable microspheres are disposed in a pattern between web substrates on a continuous, high speed manufacturing line to produce padded, insulated products useful as envelopes, mailers and other protective packaging.
