摘要:
A waterborne base coat having a special-effect color and which contains aqueous microgel as binder, 0.5 to 2 wt.-% of poly(meth)acrylic acid thickener and 2 to 7 wt.-% of non-ionically emulsified EVA copolymer wax with a drop point of the wax portion of 80 to 110C, the wt.-% in each case calculated as solids and relative to the solids content of the waterborne base coat.
摘要:
A method for coating a surface of a continuous web (W) having a first surface and a second surface with a coating powder (6, 7) comprising steps of: Allowing the web to move between a first and a second electrode (1, 2), which are in different potentials and are located on the opposite sides of the web, applying the coating powder on the surface of the web by utilizing the difference in the electric potential, and finishing the coated surface (3) of the web. The both surfaces of the web are coated essentially simultaneously by using oppositely charged electrodes.
摘要:
The invention refers to a method for forming particles or droplets of at least one substance comprising the steps of providing a foamed medium, which foamed medium comprises said substance, and forming particles or droplets of said substance at least partly by electrostatic processing. The use of foamed medium in electrostatic processing enables higher production speeds and increases the evenness of a coating layer formed by electrospinning or electrospraying the particles or droplets on a substrate.
摘要:
The invention consists in the use of a method for the common electrostatic painting of one or more components of a non-conductive material (2) and one or more components of a metallic material, wherein the component or components of the non-conductive material (2) and the component or components of the metallic material are separated from one another by gaps (4). The application to each component of a non-conductive material (2) must necessarily begin at the one or more earth contacts (1) and be continued from there without interruption.
摘要:
An improved process for electrostatically coating a medical device is described. Temporary conductivity is induced into the surface of a medical device whose surface is normally non-conductive. After inducing temporary conductivity to the surface of the device, it is electrostatically coated either through liquid formulation spray coating or through dry powder deposition. The process provides a high degree of uniformity and control over the coating such that the fine features of the device that are necessary for device function are carefully maintained after the coating is applied.
摘要:
A method for an electrostatic abluminal coating of a stent crimped on a balloon catheter is disclosed. In one form of the method, a stent-balloon assembly is formed by crimping or otherwise mounting a stent on the balloon of a catheter. A conductive wire is thereafter threaded through the lumen of the stent-balloon assembly and a charge is applied thereto. The stent may be grounded or, alternatively, be potentiated with a charge opposite to that of the conductive wire. An electrostatic spray with the same charge as that of the conductive wire may then be applied to the stent-balloon assembly. In this manner, a stent-balloon assembly which is coated on the abluminal surface but substantially or completely free of coating on the luminal surface and the outside surface of the exposed portions of the balloon is realized.
摘要:
A process for preparing a powder coated reconstituted cellulosic substrate comprising providing a reconstituted cellulosic substrate comprising cellulose based particles and a cured formaldehyde based resin, wherein an inorganic salt is dispersed throughout the substrate; applying a powder coating composition to at least one surface of said substrate; and curing the powder coating composition.
