Paint configured to provide a hydrophilic paint surface comprising a paint base and a texture imprinting additive (TIA) that provides sacrificial particles upon drying of the paint. Loss of the sacrificial particles increases roughness and reduces the contact angle with water, providing a hydrophilic surface that is wettable and hence self-cleaning. Also described are specific types of TIA, methods of making the paint, methods of making a hydrophilic surface, and kits.

Corrosion and chip-resistant coatings for high tensile steel components, such as automotive coil springs, can be formed from a coating composition comprising a primer having an epoxy resin with the proviso that the epoxy resin does not have an EEW of about 860 to about 930, a polyhydroxyl functional phenolic curing agent having a HEW of about 200 to about 500, and a platy filler. The primer contains less than 20 wt % zinc. The topcoat includes an epoxy resin having an epoxy equivalent weight of about 450 to about 1400, an elastomer-modified epoxy resin having an epoxy equivalent weight of about 1000 to about 1600, a foaming agent and a reinforcing fiber.

A coating is made by mixing an amine-terminated polymer precursor; an aromatic polyisocyanate polymer precursor; and nanotubes in the head of a spray gun and spraying the mixture onto a substrate.

The present invention relates to a process for producing a peelable coating on metallic substrates, which comprises (1) providing a metallic substrate, (2) applying a peelable lacquer to the metallic substrate, and (3) curing the peelable lacquer applied, in which, the peelable lacquer comprises microhollow spheres. The present invention also relates to a process for the chemical milling of metallic substrates.

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.

A conductive coating composition includes graphite intercalation compounds, metal particles, a binder, and a dissolving agent. The graphite intercalation compounds are compounds having a sandwich structure where various atoms, molecules, etc., are inserted between layers of graphite, which is a layered material in which carbon hexagonal net planes are laminated in parallel. The binder and the dissolving agent allow the graphite intercalation compounds and the metal particles to be bonded. The volume of the graphite intercalation compounds in the conductive coating composition is larger than the volume of the metal particles in the conductive coating composition.

A matte sheet includes a substrate and a matte coating layer. The matte coating layer is formed on the substrate. The matte coating layer has an average thickness ranging from 2.5 m to 6 m and is made from a coating composition that includes a matting agent. The matte coating layer satisfies an inequality formula of 5<d.sub.50/Ra11. D.sub.50 stands for a particle size distribution of the matting agent and Ra stands for a roughness of the matte coating layer. The matte product made from the matte sheet is also provided.

A composition comprises a thermoplastic binder, at least one optical component, and a colour correcting component. The optical component comprises retroreflecting particles. The color correcting component comprising at least one pigment and is selected to selectively absorb a wavelength of light. The thermoplastic binder and at least one optical component has a first colour and the colour correcting component has a second colour. The first colour and second colour are a complementary colour pair.

This coated metal plate is a chromate-free coated metal plate for exterior applications, which comprises a metal plate and a coating film that is arranged on the metal plate. The coating film contains 0.01-15% by volume of porous particles as a gloss control agent. If R (?m) is the number average particle diameter of the gloss control agent, T (?m) is the film thickness of the coating film, and ? is the standard deviation of the number-based particle size distribution of the gloss control agent, the coated metal plate satisfies the following formulae. (R+2?)/T?0.7 R?2.0 9?T?19.
