ANTI-MICROBIAL ADDITIVE AND PROPERTIES TO FOAM TO PREVENT MOLD
A method for forming polyurethane foams for vehicle seat components in a molding apparatus is provided. The method includes a step of directing one or more polyol compositions into a mold. Each of the one or more polyol compositions includes a polyol, water, and a catalyst. The method also includes a step of directing an isocyanate composition into the mold, the isocyanate composition including one or more isocyanates. The one or more polyol compositions and the one or more isocyanates are combined into a reaction composition that forms a foamed vehicle seat component. Characteristically, the mold has a shape that defines a foamed vehicle seat component. Characteristically, either the one or more polyol compositions and/or the isocyanate composition includes a liquid antimicrobial agent that is a liquid at temperatures above 10° C.

Method for producing superabsorbent polymer
The present invention relates to a superabsorbent polymer and a method for producing the same. The superabsorbent polymer includes a core layer polymerized with monomers having carboxylic group, a first shell layer formed from a surface crosslinking agent, and a second shell layer formed from zingiberaceae extracts. By a surface modification on the first shell layer performed from a specific amount of the zingiberaceae extracts, the superabsorbent polymer produced according to the method for producing the same has a good antimicrobial property and deodorizing effects, and retains an original absorbent property.

Antifouling coating composition, antifouling coating film, antifouling substrate, and method for improving storage stability of antifouling coating compositions
In one aspect, the invention has an object of providing antifouling coating compositions which have high resistance to fouling, in particular, fouling by slime, can form coating films with excellent properties such as strength and rubber properties, exhibit appropriate viscosity (sprayability and coating film surface leveling properties during spray coating) and sagging resistance, and have high storage stability suppressing deteriorations of these properties. To achieve the object, the invention provides an antifouling coating composition including (A) a diorganopolysiloxane having at least two silanol groups in the molecule, (B) an organosilane and/or a partial hydrolyzate condensate thereof having at least two hydrolyzable groups in the molecule, and (C) a pyrithione metal salt. The antifouling coating composition can be prepared from a kit in the form of a multiple-component system including respective packages of a component including the component (A) and the component (C), and a component including the component (B). In the (kit for the preparation of the) antifouling coating composition, the pyrithione metal salt (C) functions as an effective ingredient for achieving excellent antifouling properties, in particular, anti-sliming properties, and also as an effective ingredient for improving storage stability.
Cellulose Based Anti-Viral Anti-Microbial Spray Coating
A cellulose based anti-viral/anti-microbial coating.
NON-ABLATIVE MULTI-LAYER COATINGS THAT PREVENT WATER-DERIVED DAMAGE, CORROSION, AND DETERIORATION FROM BIOLOGICAL CHEMICAL PROCESSES AND THAT ARE APPLIED DURING BOAT MANUFACTURE
Methods of forming a boat hull include applying an outer polymer layer onto a hull mold, the outer polymer layer being impregnated with a biologically active chemical substance that inhibits biofouling-induced chemical, biological, and bio-proliferative damage. An inner polymer layer is applied onto the outer polymer layer, the inner polymer layer being impregnated with a biologically active chemical substance that inhibits biofouling-induced chemical, biological, and bio-proliferative damage. One or more layers of fiberglass matting are applied on the inner polymer layer, the fiberglass matting being saturated with a polymer selected from one of a group of polymers comprising a vinyl ester polymer, a phthalic unsaturated polyester polymer, and an epoxy polymer.
Enhancing the antimicrobial activity of biocides with polymers
Disclosed are compositions comprising a) an antimicrobial agent, which is selected from the group consisting of biocides containing halogen atoms and/or containing phenolic moieties, formic acid, chlorine dioxide, chlorine dioxide generating compounds, dialdehydes; components containing an antimicrobial metal such as antimicrobial silver, and b) a polyamine, especially a polyethylenimine. The polyamine is effective as a booster for the antimicrobial agent.
