  • Patent number: 11718076
    Abstract: A multilayer co-extruded film includes an inner layer positioned at a first surface of the multi-layer film that is intended to be oriented toward an object being wrapped with the film; an outer layer positioned opposite the inner layer at a second surface of the multi-layer film that is intended to be oriented away from the object being wrapped with the film; and at least one core layer positioned between the inner layer and the outer layer. A method for making a biodegradable tensioning film that is composed of an inner layer, an outer layer and one or more core layer positioned therebetween includes extruding a three-layer film on a three-layer extruder. Each of the inner layer, the outer layer and the one or more core layer is primarily composed of a polymeric material that is biodegradable and compostable.

  • Patent number: 9518328
    Abstract: A gel-forming corrosion inhibiting composition may be employed to protect a metal article from corrosion. The gel-forming corrosion inhibitor composition is combined with water and delivered to an enclosed space at least partially defined by the metal article. Subsequent to delivery, the combination forms a gel to sustainably fill the enclosed space, thereby protecting the metal article from corrosion.

  • Patent number: 8603603
    Abstract: A corrosion inhibiting agent is provided as a finely ground powder that is dispensed into a sheath or other casing enclosing a metal bar, cable, or other tension member. The agents are produced by preparing salts of amines with benzoic acid or nitric acid, drying the salts, and grinding and screening the salts to provide a desired maximum particle size. Also disclosed is a dry fogging system through which the powder is applied to metal tension members enclosed in polymeric sheaths or other fluid tight casings.
