A printable antimicrobial medium is disclosed, including a substrate layer having a first surface which may include a first area, a second surface opposite the first surface which may include a second area. The printable antimicrobial medium also includes a first adhesive deposited on the first area, a liner layer releasably secured to the substrate layer by the first adhesive, and a first antimicrobial dry marking material deposited on at least a portion of the second area of the substrate layer. The printable antimicrobial medium may include a first score line arranged to separate one or more layers of the printable antimicrobial medium into a first portion and a second portion, and an antimicrobial dry marking material may include copper oxide deposited on at least a portion of the second area of the substrate layer.

A manufacturing method described in the present invention provides antimicrobial copper-containing polyurethane foams by embedding microparticles of metallic copper (Cu), cuprous oxide (Cu.sub.2O), cupric oxide (CuO), or cuprous iodide (CuI), or combinations thereof, into polyurethane foams, wherein said microparticles are homogenously distributed throughout the formed polymeric matrix of said foam. The method combines these copper-containing microparticles, or polyurethane liquid additive containing these particles, mixed in polyol with isocyanate.

Methods of protecting a propeller include applying an inner polymer layer onto a propeller. The inner polymer layer is impregnated with a biologically active chemical substance that inhibits biofouling-induced chemical, biological, and bio-proliferative damage and that does not chemically or galvanically interact with a material of the propeller. An outer polymer layer is applied onto the inner polymer layer, the outer polymer layer being impregnated with a biologically active chemical substance that inhibits biofouling-induced chemical, biological, and bio-proliferative damage and that repels biofouling organisms to prevent invasion of the inner polymer layer.

The invention relates to a hull of a vessel having characteristic surface properties, allowing an increase in surface runoff while benefiting from an inherent anti-fouling property and an original aesthetic appearance. Furthermore, the invention allows the incorporation of said outer composite envelope into the structure of the hull, thereby preventing delamination problems and inherently providing a vessel hull with the above-mentioned properties.

A polymeric blend composition comprising: (a) from about 1 to about 99 wt. % of a polymer; and (b) from about 1 to about 75 wt. % poly alpha-1,3-glucan is disclosed. The addition of alpha-1,3-glucan as a polymer filler can increase the tensile modulus, tensile strength and oxygen barrier properties of the polymeric blend composition.

The present invention relates to a method for obtaining a polymeric material incorporating metallic particles, a polymeric material incorporating metallic particles and the use of said polymeric material.

This invention relates to a coating comprising prepolymer and monomers for application onto polyurethane for chemical resistance, abrasion resistance, water proof etc. Usually polyurethane is porous and does not have sufficient stain, abrasion and chemical resistance. The said coatings developed using technology of chemical grafting that involves the use of prepolymers, monomers, catalyst, graft initiator, wetting agents, fillers and other ingredients of the composition. The coating thus obtained when applied on the polyurethane allows obtaining graft polymerization, thereby forming a polymeric film chemically attached to the substrate. The polyurethane substrate is reacted with graft initiator which creates the reaction sites on the substrate via free radical mechanism. This in turn renders the substrate receptive to attachment of monomers/prepolymers forming polymeric film that is chemically bonded to the substrate which has then the desired property in terms of stain resistance, abrasion wear, crock, water, chemical resistance and other properties.
