Abstract: A method of altering a property of a surface includes suspending a plurality of low surface energy particles in a solvent, agglomerating the suspension of particles, and subjecting the suspension of particle agglomerates to electrophoretic deposition onto a substrate for a predetermined time. The altered surface may be superhydrophilic or superhydrophobic.

Abstract: A method for the electrophoretic coating of workpieces with a coating medium, in particular lacquer, and a coating installation are described. In the method, at least one workpiece is immersed in the coating medium. With a voltage source, a d.c. voltage is applied between the workpiece and at least one electrode immersed in the coating medium. The d.c. voltage is increased continuously, in an essentially stepless manner, throughout virtually the entire coating operation in such a way that the coating current density on the surface of the workpiece remains essentially constant over time.

Abstract: This invention relates to the control of radiant thermal energy and more specifically to highly Thermal Infrared (IRT) reflective pigments for use in decorative coatings for buildings or other areas where the control of IRT energy and visual decoration are required. Control of the spread of thermal energy in domestic building through passive techniques reduces energy consumption by reducing reliance on heating in cool environments and cooling air-conditioning in warm environments. A number of paint formulations having low emissivity in the thermal infrared exist which are based on variants of conventional decorative paint fluids. There are a number of problems associated with such formulations such as susceptibility to damages and high emissivity for certain colour pigmentations. The present invention proposes a low emissivity flake (1) for use in a paint formulation which substantially overcomes the problems associated with the prior art.

Abstract: With the use of a lead-free cationic electrodeposition coating composition containing a sulfonium-modified epoxy resin, an amine-modified novolak-type epoxy resin, and a blocked isocyanate curing agent as a binder resin, wherein the content of volatile organic components is 1% by weight or less, the coating liquid conductivity is 1000 to 2500 &mgr;S/cm, and the minimum film-forming temperature of the coated layer electrodeposited on an object to be coated is 20 to 35° C., electrodeposition coating is carried out at or above the temperature which is lower by 2° C. than the minimum film-forming temperature and at or below the temperature which is higher by 6° C. than the minimum film-forming temperature.

Abstract: A component useful for a plasma reaction chamber includes a heat sink such as a temperature-controlled support member and a heated member such as an electrically powered showerhead electrode. The showerhead electrode is peripherally secured to the support member to enclose a gas distribution chamber between a top surface of the electrode and a bottom surface of the support member. A heat transfer member extends between the electrode and the support member and transfers heat from an area of temperature buildup on the top surface of the showerhead electrode to the bottom surface of the support member in order to control the temperature distribution across the showerhead electrode.

Abstract: A method and apparatus for monitoring electrodes for the electrodeposition of paint onto metallic workpieces includes detecting current from the electrodes and displaying a plot of current versus time. A method and apparatus for controlling electrodeposition of paint onto metallic workpieces includes monitoring current from electrodes over time and adjusting a rate of current increase over time. The monitor and/or control may be performed for each electrode individually or for the electrodes as a group. The monitor and/or control allows bad and/or poorly positioned electrodes to be located. The monitor and/or control may be used to stop the electrodeposition coating after a sufficiently thick coating has been obtained.
