Abstract:
Methods of making components for a medicinal delivery device are described, in which a primer composition comprising a silane having two or more reactive silane groups separated by an organic linker group is applied to a surface of a component, then a coating composition comprising an at least partially fluorinated compound is applied to the primed surface. The surface may be a polymer surface. Corresponding coated components and a medicinal delivery device are disclosed. Methods of making metal components are described in which a coating composition comprising an at least partially fluorinated compound is applied to a surface cleaned with a solvent.
Abstract:
Provided are robust paint coating systems on metal-coated plastic substrates and processes for forming such material systems as decorative components. An organometallic adhesion promoter is applied to a metal-coated plastic substrate. The metal coating comprises chromium (Cr), nickel (Ni) or combinations thereof. The organometallic adhesion promoter comprises (i) a transition metal selected from the group consisting of: zirconium (Zr), titanium (Ti), chromium (Cr), and combinations thereof, (ii) a first ligand complexed to the transition metal comprising an organofunctional group, and (iii) a second ligand complexed to the transition metal having a hydrolysable functional group. Then, one or more organic paint precursor materials are applied thereon. The hydrolysable functional group is capable of reacting with the metal-coated substrate and the organofunctional group with at least a portion of the organic paint precursor material to form a robust polymeric paint coating having a robust bond with the metal-coated plastic substrate below.
Abstract:
A plastic overmold aluminum extrusion including at least one plastic overmold (14) and aluminum extrusion (12). The aluminum extrusion (12) is formed with sufficient cross sectional properties and features such as an internal web (16) to help prevent undesirable collapses under injection or compression molding pressures. This improves part geometry and strength while minimizing weight. A plurality of protrusions (32) and/or local deformations on an outer wall of the extrusion can be used to create strong mechanical interface to the plastic. Localized deformations can result from a combination of the applied plastic pressure under injection or compression molding pressures and the proximity of outer gaps of the internal web structure. A process of making the plastic overmold aluminum extrusion includes inserting at least one aluminum extrusion into a mold without mandrels and delivering plastic forming the plastic overmold.

Embodiments of a method of pretreating a metal substrate prior to painting comprise applying a first coating solution onto the metal substrate wherein the first coating solution comprises polyaniline particles at a pH less than 7 to yield a first coating on the metal substrate, rinsing the metal substrate to remove unreacted polyaniline particles, and applying a second coating solution post-rinse which comprises at least one acid and a silane composition at a pH less than 7 to yield a second coating on the metal substrate.
Abstract:
The present invention relates to a magnesium alloy with a dense surface texture and a surface treatment method thereof, and more specifically to a magnesium alloy which comprises: a parent material including magnesium or magnesium alloy; a surface-modified layer which is formed on the surface of the parent material and includes Si; and a coating layer formed on the surface-modified layer, wherein the surface-modified layer comprises a "-Si-O-Mg-" structure, and a surface treatment method thereof.
Abstract:
A method for cleaning hard surfaces at the micro level incorporates a two-phase process that initially cleans a surface and then seals the surface. The cleaning phase implements a cleaning solution that penetrates the surface of equipment and removes dirt and debris at the micro or nana level of the equipment. The sealing phase of the method seals the surface of equipment such that gaps at the micro level are filled in to prevent debris from accumulating at the micro-level of the surface of the equipment. The sealed surface provides improved aerodynamic flow of air across the hard surface.
Abstract:
The invention relates to a method for applying a single-layer or multi-layer anti-corrosion coating on a metallic substrate being part of a pipe or a duct accessory to be buried or submerged for conveying a fluid such as water, petroleum products, gas or sanitising products. According to the invention, the method comprises: a) preparing the surface of the substrate by mechanical means only; b) applying an adhesion promoter on the prepared surface comprising a an aqueous solution of at least one silane without any further chemical process; c) applying a layer of an epoxy-resin powdery paint on the surface coated with the adhesion promoter; and d) applying at least one thermal process to the surface at least of the substrate, wherein at least one step d) for thermal processing is carried out between steps a) and b) or between steps b) and c).
