A composition comprising a first, synthetic gel and a second gel is useful for the preparation of waterborne multicolor paints.

A multifunctional broad spectrum antimicrobial composition is described. The composition can be incorporated into a wood preservative, or used as an additive to provide antimicrobial properties to water-based wood coatings. The composition is a concentrated water-miscible emulsion containing 3-iodo-2-propynyl N-butylcarbamate (IPBC), carbendazim (BCM) and propiconazole (PPCZ), and has antimicrobial activity against a wide variety of fungal organisms, including surface molds, blue stain fungi and wood rotting fungi. The composition can act as an in-can preservative and is useful for antimicrobial protection of wood and wood-based substrates.

An aqueous coating composition having good freeze-thaw stability and providing coatings with good stain resistance.

The invention relates to novel antimicrobial surfactants and their application in antimicrobial coating systems, in particular water borne coatings. Provided is a method for providing an antimicrobial surfactant, comprising the steps of: (a) providing a hyperbranched polyurea having blocked isocyanates at the end of the polymer branches by the polycondensation of AB.sub.2 monomers; (b) introducing tertiary amine groups by reacting said blocked isocyanates of the hyperbranched polyurea with a tertiary amine compound that is functionalized with OH, NH.sub.2, SH, or COO; and (c) quaternization of said tertiary amine groups by reacting with an alkylating agent to obtain a quaternized hyperbranched polymer having antimicrobial surfactant properties.

The present invention provides a polyacrylic acid copolymer emulsion, an organic-inorganic composite waterproof coating, preparation method thereof, and a waterproof coiled material. It can solve the problem that the granules dropping out from the prior waterproof membrane easily. The organic-inorganic composite waterproof coating according to the invention is prepared by compositing organic granules and inorganic granules, wherein the organic coating locks the inorganic granules, and prevents the inorganic granules from dropping out. Some exposed inorganic granules take part in the cement hydration reaction, and increase the bonding strength with the post-poured concrete. Furthermore, the organic-inorganic composite waterproof coating according to the invention does not need a buttering. It can reduce waste without an adhesive-resist insulation film/paper. Experiments prove that the peeling strength between the organic-inorganic composite waterproof coating and the concrete according to the invention is above 2.0 N/mm after being exposed to the sunshine for 8 weeks.

A composition is provided comprising a high viscosity amino functional silicone fluid, a surface modified colloidal silica, and a nanodiamond slurry. The composition is characterized by providing a protective coating and enhancing the appearance of a wide variety of painted and unpainted vehicle exterior material surfaces, including rubber, vinyl, metal, metal alloys, chrome, glass, carbon fiber, aluminum, plastic made from renewable sources, and plastic made from non-renewable sources.

The invention concerns a storage-stable polymer-bonded composition for the formation of coatings on buildings and the like, comprising at least one organic binder, at least one filler and/or pigment, water in order to produce a pasty consistency in the composition, a buffer system which comprises at least one basic silicate, at least one substance which retards the condensation of the basic silicate, as well as optional conventional additives.

The present invention relates to an anti-bacterial and anti-dust coating for air ducting. In one embodiment, the anti-bacterial and anti-dust coating comprises: a polymer emulsion; a cross linking agent; a film forming agent; a filler and anti-dust agent; an anti-bacterial agent; hardener nanoparticles; a defoamer; and water. The anti-bacterial agent can be in powder or in liquid form. The coating can be applied on the inner surface of metal air ducting to reduce dust aggregation and prevent growth of bacteria, mold and mildew that causes stains and odors inside air ducting. With the aids of nanotechnology, various specific nanoparticles are added in the waterborne polymer emulsion to provide the anti-bacterial, anti-dust, anti-acid, anti-alkali, good flexibility and hardness for the coating. The product is also tested to be flame retardant and water resistance for increased safety in air ducts.

A composition, characterized in that it comprises 1,2-dibromo-2,4-dicyanobutane (DBDCB) and zinc pyrithione (ZPT) as active components.

Disclosed is an antimicrobial coating and antimicrobial laminate that can be used on surfaces to prevent the spread of bacteria and viruses. Spray-on techniques can be used with antimicrobial agents mixed with an air-drying antimicrobial coating and a heated liquid plastic antimicrobial coating. Efficacy of the antimicrobial coating can be monitored by detecting changes in texture, color, opaqueness, fluorescence, and other techniques. Soft plastics and acrylics can be used to suspend the antimicrobial agents to provide better efficacy in the release of antimicrobial agents over time.
