A composition and method for inhibiting stain formation in a floor covering. The composition includes a copper glycine complex in combination with magnesium hydroxide and a carrier. The composition can be advantageously applied to a wood-based substrate upon which a floor covering is overlaid. Flooring assemblies that include the composition are also provided.

Composition and method for inhibiting stain formation in a floor covering

In one aspect, the present invention provides a formulation for sealing the edge of a wood-based panel. The formulation includes a butylacrylate latex, a solution of a wax in oil, a surfactant, and water. In another aspect of the invention, a wood-based panel that is edge-sealed with a sealant formulation is provided.

Edge sealant formulation for wood-based panels

A coating that inhibits stain formation in floor covering. The coating includes a copper amine complex, preferably a copper morpholine complex, and is advantageously applied to an underlayment upon which a floor covering is adhered. Coated panels and floor assemblies that include the coating are also described.

An anticorrosion formulation for coating wood based panels to inhibit the corrosion of metallic members in contact with the panel is disclosed. In one embodiment, the formulation includes water, a binding agent, boric acid, and a group II metal hydroxide selected from beryllium hydroxide, magnesium hydroxide, calcium hydroxide, strontium hydroxide, and barium hydroxide. A wood-based panel coated with the anticorrosion formulation and a method for forming the coated panel are provided.

Coating for wood based panels to reduce corrosion of attached metallic member

Wood-based products, to which an overlay material is attached, are pretreated with an aqueous suspension of alkaline, inorganic, multivalent compound such as magnesium hydroxide and a binding agent and then allowed to dry fixing the antistaining compound on the surface of the wood member. Selected additives can be added to the aqueous suspension to enhance application and surface properties. Thereafter the treated members are installed, a typical application being as wood-based underlayment or structural subflooring in flooring construction. When a vinyl floor covering material is attached to the pretreated panel, the treatment functions as a stain blocker preventing unsightly staining of the vinyl floor covering over time.

Stain blocking treatment for wood based panels

When birds are placed upright on the interior surface of an open-ended, non-vertical rotating drum, the birds turn, regardless of their initial orientation, so as to face 'uphill' in the drum. The birds leaving the drum are all found to have the same orientation, and thus can be more easily hung on shackles. An apparatus for performing the method comprises a frame, bearings connected to the frame, an open-ended drum supported for rotation about its longitudinal axis by the bearings, means for rotating the drum about its axis, means for depositing a series of birds on the interior surface of the drum, at a first end of the drum as it rotates, and means for receiving birds exiting from a second end of the drum. The drum preferably declines from the first end toward the second at a depression angle of about 15.degree..
