The invention pertains to an antifouling coating composition comprising a copper acrylate polymer, 2-(p-chlorophenyl)-3-cyano-4-bromo-5-trifluoromethyl pyrrole (tralopyril), and solvent, with the coating composition being substantially free of further biocidal compounds, wherein the copper acrylate polymer is present in an amount of 60-99 wt. % and the tralopyril is present in an amount of 0.1-30 wt. %, the weight percentages for copper acrylate polymer and tralopyril being calculated on the dry weight of the coating composition. In one embodiment, the coating composition comprises 30-70 wt % of solvent, the weight percentage of solvent being calculated on the wet weight of the coating composition. It has been found that the coating composition according to the invention combines a good antifouling performance against both weed and shell fouling, for at least 12 months, i.e. a yacht season, with a high gloss finish, and, when a suitable application method is used, a smooth and level surface.

An antiglare glass substrate includes a glass substrate having a first main surface and a second main surface that is opposite to the first main surface. The first main surface has undergone an antiglare treatment and a fluorine-containing organosilicon compound coating film as an antifouling film is laminated thereon. The first main surface partly includes a non-antiglare-treated portion that has not undergone the antiglare treatment. The non-antiglare-treated portion has a surface roughness Ra of less than 10 nm. A difference in height along a plate thickness direction of the glass substrate between the antiglare-treated portion that has undergone the antiglare treatment and the non-antiglare-treated portion is 10 m or larger and 200 m or less.

A water-based coating makes it possible to provide a highly water-repellent coating film and has excellent film formability. The water-based coating contains (a) a graft copolymer (A) containing a specific amount of a non-crosslinked polyorganosiloxane and a graft part and (b) a polymer (B) having a specific feature. The specific feature of the polymer (B) is that (i) an amount of the polymer (B) is a specific amount, or (ii) a complex of the graft copolymer (A) and the polymer (B) has a weight-average molecular weight that is not more than a specific value.

In regard to a conventionally known resin composition for an antistatic hard coating to which an ionic liquid is added and an antistatic hard coating using it, there is a problem that it is difficult to achieve both an antistatic ability and high hardness. In order to solve the problem, used is a resin composition for an ultraviolet curing hard coating, the resin composition containing: an electrically conductive polymer that contains polythiophene (A) including at least two structural units represented by a specific general formula; an ultraviolet curable resin (B); and a solvent (C).

An antimicrobial formulation that can be directly added into a composition or onto a surface of a composition (e.g., forming a surface coating on a composition or device). The antimicrobial formulation includes sodium pentaborate, di-sodium tetraborate decahydrate, titanium diborite, titanium borate, sodium pyrithione, zinc pyrithione, benzhetonium chloride, or any combination thereof.

The present invention aims to provide a water-repellant and oil-repellant coating composition which has good water-repellant and oil-repellant characteristics and further improves abrasion resistance, and a transparent film produced therefrom. The present invention is a water-repellant and oil-repellant coating composition comprising a first organic silicon compound (A) in which a fluorine-containing group having a perfluoroalkyl group or a perfluoropolyether group on the free end side thereof and a hydrolyzable group are bonded to a silicon atom thereof, and a second organic silicon compound (B) that is a hydrolyzable silane oligomer or a compound in which a carbon fluoride-containing group and a hydrolyzable group are bonded to a silicon atom thereof and that has a vapor pressure at 100 C. of 1 atm or less.

Provided is a method for preparing an alkaline red mud coating for preventing marine organism attachment, including: (1) mixing stearic acid and absolute ethanol by stirring to obtain a mixed solution; (2) mixing the mixed solution and a red mud powder to obtain a mixture, and drying the mixture to obtain a modified hydrophobic red mud powder; (3) adding benzyl glycidyl ether into an epoxy resin and conducting dispersion to be uniform to obtain a mixed system, adding the modified hydrophobic red mud powder into the mixed system, continuing the dispersion to be uniform to obtain a blend, and grinding the blend to obtain an antifouling coating material; and (4) during use, mixing the antifouling coating material with a polyamide curing agent to obtain a mixture system, and applying the mixture system onto a surface of building to form the alkaline red mud coating for preventing marine organism attachment.

The present invention relates to compositions with self-cleaning properties. More particularly, the invention concerns coatings or paints comprising particles coated with a catalytically active composition. In particular, a self-cleaning coating composition (paint) is provided, comprising micro-sized particles coated with a functional layer, wherein the micro-sized particles are hollow or solid beads, or any combination/ratio of hollow and solid beads, wherein the beads comprise one or more material(s) selected from ceramic material(s); polymeric material(s); cermet material(s); metallic material(s); pigmented material(s); light-absorbing and/or light reflecting material(s); including any combination thereof, wherein said layer is covalently bound to said particles, wherein the photocatalytic layer comprises TiO.sub.2 in the crystal form of anatase; and wherein the coating composition (paint) comprises less than 0.1 anatase particles derived/released from the micro-sized beads, determined as weight/weight of released anatase/total amount of anatase. The invention provides paint essentially without presence of unbound anatase crystals which is highly undesired, as it is believed that their presence has a negative influence on essential components of the paint, such as binder, pigment and/or additives and furthermore, anatase may cause eye, skin, and respiratory tract irritation.
