摘要:
We describe a new approach to fabricate polymeric materials with surface structures for applications as anti-reflective, anti-icing, superhydrophobic, superhydrophilic, de-wetting, and self-cleaning coatings. In some variations, a surface-textured layer comprises first microdomains and second microdomains each containing polymerized cross-linkable photomonomer, where the first microdomains have a higher average cross-link density than that of the second microdomains. The first microdomains and the second microdomains are in a peak-valley surface topology, providing surface texture with no filler particles. In some variations, a method to fabricate a surface-textured layer comprises: applying a cross-linkable photomonomer layer to a reflective substrate; exposing the photomonomer layer to a collimated light beam with no spatial variation, to initiate polymerization in first microdomains; and polymerizing other regions of the photomonomer layer to form second microdomains that are spatially separated from the first microdomains. The first microdomains have a higher average cross-link density compared to the second microdomains.

A method for forming a multilayer coating film is provided. The method includes coating at least one object with an aqueous primer coating composition, an aqueous first colored coating composition, an aqueous second colored coating composition, and a clear coating composition, in that order. The aqueous primer coating composition contains a component (A) which contains a polyolefin resin, a component (B) which contains a polyurethane resin, a curing agent (C) and electrically conductive carbon (D). The aqueous first colored coating composition and aqueous second colored coating composition each contain a core/shell emulsion. The clear coating composition contains a hydroxyl group-containing acrylic resin, a polyisocyanate and a melamine resin. The method improves the appearance, chipping resistance, adhesive properties and low temperature impact properties of a coating film.

A transparent, heat-sealable coating for transparent PET packaging foils can be provided by using a heat-sealable lacquer based on styrene-containing copolymers, on poly(meth)acrylates, on at least one polyester and optionally on a tackifier, and also the process for the sealing of a foil coated with this lacquer. It is surprising here that, despite the use of a rubber based on styrene-containing polymers that is not optically compatible with polyesters and polymethacrylate, the transparency of the heat-sealable coatings is still very high.

A material composition for manufacturing a translucent conductive film includes a fluid. The material composition further includes nanostructures disposed within the fluid. The material composition further includes a component that modifies a structure of a joint formed between at least two nanostructures of the plurality of nanostructures after the component is activated. The component may be activated by applying heath or optical radiation to the component.

A charging cable is provided. The charging cable includes wires for supplying power, a wire for transferring a signal and a sheath, and exhibits substantially improved mechanical properties such as low-temperature flexibility and abrasion resistance, substantially improved chemical properties such as oil resistance and substantially improved electrical properties such as insulation resistance. Moreover, the charging cable has improved electrical, mechanical and chemical properties by improving insulation resistance, heat resistance and low-temperature flexibility of wires, as compared to conventional wires coated with polyvinylchloride (PVC).
摘要:
The present invention provides a mono coating film type waterborne coating composition comprising halogen free polyolefin resin, acryl polyol, acryl emulsion, and a solvent. According to the present invention, adhesion to a polyolefin substrate is excellent, and physical/chemical properties may be maintained with a single coating film instead of the currently used dual coating films, by a halogen free waterborne composition with physical/chemical properties similar to or more excellent than the existing oil coating or halogen-containing coating composition. Since these effects may be sufficiently obtained with a single coating film, consumption of coating may be reduced about 30˜40% compared to the existing method, and particularly, cost reduction may be expected through decrease in equipment required for dual coating film, energy for drying coating film, attractive force of coating, productivity increase, and the like.

The present invention provides a polyolefin resin composition for metal coating, which is excellent in separation resistance, weather resistance and corrosion resistance, can be industrially produced without difficulty even by an existing apparatus, and is assured of excellent scratch resistance without using a surface coating agent; a resin film using the composition; and a resin-coated metal material. The polyolefin resin composition for metal coating comprises at least (A) a polyolefin resin, (B) a layered inorganic material, (C) an olefin containing oligomer containing a functional group having polarity and (D) a rubber-like elastic material.
