Abstract:
The invention relates to a process for producing hydrophobic nanostructured surfaces, which features the application of a dispersion of water in hydrophobic oxides to the surface to be treated and the subsequent removal of the water, and also to the surfaces produced by means of this process and to their use for producing soil- and water-repellent surfaces on objects.
Abstract:
Coated articles may comprise one or more coating layers, including water resistant coatings. A method comprises applying such coating layers by dip, spray or flow coating. The methods can make coated containers, preferably comprising polyethylene terephthalate, from coated preforms. In some methods, the aqueous solutions, dispersions, or emulsions are substantially or completely free of VOCs.
Abstract:
Methods for improving the barrier of a substrate having a barrier coating are disclosed. The methods generally comprise contacting the barrier coated substrate with an acid. Substrates treated according to this method are also disclosed.
Abstract:
As the chemical resistance of sol gel based coatings is superior to that of regular decorative coatings based on organic material, sol gel coatings are generally very well suited to serve as coatings that are exposed to cosmetic formulations, such as lotions and shampoos. The invention relates to a utensil which is provided with a sol gel coating comprising an organosilane compound that has been fluorinated. The invention also relates to the use of such a sol gel coating on a utensil.
Abstract:
It is an object of the present invention to provide a method of coating a plastic molding which is appropriately applicable to various plastic substrates, an ultraviolet-curable under coating for metal evaporation, which is to be used in that method of coating, and a plastic molding obtained by that method of coating.A method of coating a plastic molding comprising steps of applying an ultraviolet-curable under coating for metal evaporation to a plastic substrate, then subjecting the coated substrate to ultraviolet irradiation to form an under coating film, evaporating a metal on the coating film and applying a clear coating to the metal surface to form a clear coating film layer, wherein the ultraviolet-curable under coating for metal evaporation comprises an acrylic resin comprising, as a constituent, at least one monomer (a) selected from among dicyclopentanyl (meth)acrylate, dicyclopentenyl (meth)acrylate and isobornyl (meth)acrylate, a compound having at least two (meth)acryloyl groups within the molecule, and a photopolymerization initiator.
Abstract:
The invention relates to surfaces with hydrophilic properties and a method for producing such surfaces. Surfaces are provided with hydrophilic properties by applying a coating containing hydrophilic silicic acid by means of the inventive method. Said surfaces can be textile or polymer surfaces, metallic or wooden surfaces. The silicic acid can be permanently connected to the polymer surface or be in the form of a non-fixed coating. The inventive hydrophilic silicic acid is applied in a very simple manner by applying a suspension containing silicic acid particles in a solvent on the corresponding surface, whereupon the solvent is removed or the silicic acid particles are fixed to the surface by means of a carrier. Condensing devices of dehumidifiers, foams or sponges are examples of surfaces that can be provided with the inventive hydrophilic surfaces.
Abstract:
A method of powder coating thermo powder resins to non-conductive plastic substrates, in particular, to polyamide materials and other non-conductive plastic substrates. It discloses a method for powder coating a non-conductive plastic substrate comprising the following steps: (a) cleaning said substrates to remove any contaminants or mold release agents therefrom; (b) applying an adhesive/sealer to said substrate; (c) curing said adhesive/sealer by means of heat; (d) applying a thermosetting powder to the hot substrate; and (e) curing said thermosetting powder with heat.
Abstract:
A continuous process for manufacturing self-assembled multilayer coatings, and more particularly, to a continuous process for making multilayer coatings in a roll-to-roll process. A predetermined number of alternating nanoscopic layers of positively charged and negatively charges species are deposited on a moving substrate to form a multilayer composite coating on a substrate in roll form.
Abstract:
A method for coating a golf ball, including the steps of providing a golf ball component; providing a polymeric material; creating a particulate from the polymer material; charging at least one of the component or the particulate; fluidizing the polymer particulate; and coating the golf ball component with a thin layer of the polymer material by placing the golf ball component within the fluidized particulate.
Abstract:
The present invention provides a method for forming a coating film on a plastic substrate which comprises: (1) coating the plastic substrate with an aqueous white primer (A) having a water content of 15 to 48 wt. % to form a coating film having an L* value of 80 or more, (2) heating the coating film of the primer (A) to adjust the water content of the film to 1 to 10 wt. % and the surface electrical resistivity value of the film to less than 109 null/square, (3) electrostatically coating the coating film of the primer (A) with a thermosetting clear colored coating composition (B), (4) electrostatically coating the uncured coating film of the coating composition (B) with a thermosetting clear coating composition (C), and (5) baking the three-layer coating film to obtain a cured multilayer coating film having an N value of 8.5 or more.
