The present invention refers to a process for the preparation of an additive with a metallic hydroxide base, and especially of magnesium hydroxide, to be integrated in coatings with the purpose to give them higher flame retarding properties. The hydroxide has an average particle size that is selected from between 1 nanometer and 10 microns preferable with a wide variety, the magnesium hydroxide is submitted to a treatment of washing and dispersion, mainly so that they efficiently are dispersed in, and do not interfere with, the desired properties of the coating. The nature of the coating function is selected from the materials and the conditions of the treatment, as well as the size of the particle. The objective coating can have a base of water, solvents, oil, and alcohol. Compared with coatings formed with other flame retarding compositions, the additive of the invention presents less loss of weight by means of burning through ASTM D1360 standards.

The present invention further provides a multi layered coating film obtained by a method for producing a multi layered coating film in which the luster coating composition is used, and a multi layered coating film formed thereby.

The present invention relates to the use of coating compositions, comprising shaped transition metal, especially silver, particles and a binder, wherein the ratio of pigment to binder is preferably such that the resulting coating shows an angle dependent color change, for the production of security elements and holograms. When the coating compositions of the present invention are used in coating a hologram the obtained products show a an angle dependent color change (flip/flop effect), different colors in reflection and transmission, an extremely bright OVD image and extremely strong rainbow effect, high purity and contrast.

The present invention provides a method for preparing an uneven particle layer, an organic light emitting diode device and a display device. The method for preparing an uneven particle layer includes the following steps: forming a nanoparticle layer on a substrate; heating the substrate to fuse nanoparticles that are in contact with the substrate, whereas the nanoparticles on the surface keep a solid state; and cooling the substrate to form a nanoparticle layer with an uneven surface. The method of the present invention is simple in process, and industrial production is easy to achieve. The substrate including the uneven particle layer is applied to the OLED device, so the propagation direction of rays can be changed so as to avoid total reflection on an interface and thus improve the light extraction efficiency of the OLED device. The OLED device prepared in the present invention is suitable for various display devices.

An overcoat that imparts a superhydrophobic surface to a painted surface of an object is a suspension of hydrophobic particles in a polymeric binder and a plasticizer in a solvent or mixed solvent. The particles are a metal oxide that is surface functionalized with a fluorinated alkyl silane or an alkyl silane. Surfaces coated using this paint display contact angles in excess of 150° and resist abrasion while retaining superhydrophobicity.

A fast drying, heavy metal-free, high performance coating composition with outstanding UV resistance, and excellent corrosion resistance coupled with fast dry and long pot life. This coating can be applied over DTM, such as blasted cold rolled steel, or treated cold rolled steel, aluminum and treated aluminum. High corrosion resistance without sacrificing gloss or UV resistance achieved by selecting proper pigments and proper pigment design and packing by advantageously utilizing differing pigment morphologies (sizes and shape).
