摘要:
A liquid composition and a process for coating the composition onto a surface of a substrate in a substantially oxygen-free atmosphere, under vacuum conditions. The composition comprises one or more components, all of which components do not go into a gas or vapor phase under the vacuum conditions. The composition has an ethylenically unsaturated component composed of an ethylenically unsaturated methacrylate monomer, or a combination of an ethylenically unsaturated methacrylate monomer and an ethylenically unsaturated methacrylate oligomer. The ethylenically unsaturated component is polymerizable or crosslinkable by the application of sufficient electron beam radiation. The composition is substantially absent of ethylenically unsaturated acrylate components, substantially absent of polymerization initiators, and substantially absent of solvents. The composition optionally further comprises one or more polymers without an acrylate functional group and without a methacrylate functional group. The composition optionally further comprises one or more of waxes, pigments, and/or wetting agents.

摘要:
A metallized product includes a composite substrate or other substrate wherein at least a portion of the surface of the substrate is coated with an adhesion-promoting layer comprising resin and microballoons. A metallic coating is adhered to the adhesion promoting layer to produce the metallized surface. Methods for producing metallized products are also provided.
摘要:
Process for preparing A silver-containing, disperse, water-containing formulation useful for producing electrically conductive and/or optically reflective coatings, which comprises (i) reacting a silver salt solution with a solution containing hydroxide ions, wherein at least one of said solutions comprises a polymeric dispersant, to produce an Ag2O sol, (ii) reacting the Ag2O sol obtained from step i) with a reduction agent, and (iii) purifying the solution obtained from step ii).
摘要:
An article surface ornamental structure that is easy to work and able to form a decorative pattern of an optional design and a high-grade feeling produced thanks to the metallic luster and, if necessary, to form a third dimensional decorative pattern. A metal-coated layer is formed by depositing a metal material with metallic luster on a surface of a base material. The metal-coated layer is at least partly provided with a separation part part, in which the based material has its surface exposed to create an ornamental pattern thanks to a difference between the outer appearance of the base material and the metallic luster of the remaining metal-coated layer. With the base material and the metal-coated layer exposed, respectively, each of their surfaces is coated with a clear-coating layer made of synthetic resin material having transmittancy in order to protect the surface of the ornamental pattern.
摘要:
A coating composition for a metal thin film for coating a vapor-deposited film or sputtered film provided on the surface of a base material, comprising: a coating film forming component containing 50% by weight or more of urethane (meth)acrylate that is a reaction product of hydrogenated xylene diisocyanate and/or hydrogenated diphenylmethane diisocyanate, polyol, and (meth)acrylate having a hydroxyl group.
摘要:
The kit of optical fibers for percutaneous ablative treatment, comprises at least two optical fibers (5), each of which is equipped; at a first end with a connector (5A) to a laser source (7); and in proximity to a second end with a device (5B) for constraining to a pervious needle (9). The kit comprises a coding system that characterizes one fiber with respect to the other, allowing said fibers to be distinguished from one another.
摘要:
A method for producing an article having a decorative coating includes depositing at least a first coating layer onto at least a portion of a substrate using a physical or chemical vapor deposition method in a vacuum chamber at sub-atmospheric pressure, the first coating layer comprising a first material having a first color. The method also includes patterning the first coating layer using a non-uniform patterning process to form a patterned coating layer having penetrations through which a portion of an underlying surface is visible, the underlying surface comprising a second material and having a second color that is visually contrasting to the first color. The patterned first coating layer comprises a decorative pattern comprising features distinguishable by an unaided human eye.
摘要:
An article is coated with a multi-layer coating having the appearance of brass, nickel and stainless steel. The coating comprises a nickel or polymer base coat on the surface of said article, a chromium layer and vapor deposited on the chromium layer, a refractory metal nitride or nitride and oxide, or refractory metal alloy nitride or nitride and oxide that mimic the colors of brass, nickel and stainless steel. An oxide-containing strike layer comprised of nano-sized refractory metal crystals and/or preferentially oriented refractory metal phase with the refractory oxide for precipitation hardening. A refractory oxide layer intermediate the refractory metal strike layer and the stack layer comprised of alternative layers of refractory metal, substoichiometric refractory nitride and stoichiometric refractory nitride. This intermediate oxide layer acts as a non-conductive barrier to improve corrosion and pitting resistance. An ultra-thin refractory oxide top layer to provide further protection against corrosion.
