  • Publication number: 20250084260
    Abstract: Disclosed herein is an aqueous colloidal titanium dioxide dispersion preferably having a pH value in a range of 6.2 to 7.8 at 25° C. and including titanium dioxide particles, the titanium particles having a Z-average particle size in a range from 30 nm to 220 nm as determined by dynamic light scattering and a particle size distribution span [(D90-D10)/(D50)] in a range from 0.7 to 1.5; one or more dispersing agents comprising groups which bind to the titanium dioxide particles; one or more organic solvents; and if necessary, one or more pH value adjusting compounds. Further disclosed herein are a method of preparing such dispersions, a coating composition containing the components of such dispersions, coated substrates and methods of coating the substrates with such dispersions and a method of using of the dispersions in the manufacture of coating compositions.

  • Publication number: 20240327657
    Abstract: Disclosed herein is a multilayer coating including at least one ground coat layer, the at least one ground coat layer including at least one non-platelet-shaped titanium dioxide pigment (T); at least one midcoat layer on top of the at least one ground coat layer, and at least one clearcoat layer on top of the at least one midcoat layer; and having a lightness L* according to CIELab in the viewing angle range from ?15° to +45° of at least 80; in the viewing angle range from +75° to +110° of at least 70, if a metal effect pigment is contained in the midcoat layer; in the viewing angle range from +75° to +110° of at least 75, if no metal effect pigment is contained in the midcoat layer. Further disclosed herein are a method for producing such multilayer coating and a multilayer coated substrate.

  • Patent number: 9555508
    Abstract: Embodiments of the invention relate to a rigging table system that delivers the members from the cutting station to a location behind the workers at the rigging table, transports the members vertically below the surface of the floor on which the workers stand, horizontally transports the members underneath the floor on which the workers stand, and delivers the members vertically above the surface of the floor in front of the workers for assembly on the rigging table. The members are delivered through the use of systems that drop, slide, lift, and extend the members of the truss to the desired locations using automatic sensors or call buttons.

  • Patent number: 8174392
    Abstract: A medical item hanging storage system for medical items having stand-off readable tags, such as RFID tags, comprises storage devices comprising fixtures for holding hanging medical items, and readers for reading tags associated with each of the medical items, and tags that attached to the hanging medical items to be read by the readers. Tagging devices are used for attaching the RFID tags. The tagging devices each comprise a substrate, possibly including a hook, an adhesive portion for attaching the substrate to the medical item, and at least one spreader for separating RFID tags of adjacent medical items and/or other tags to facilitate reading of the tags.

  • Patent number: 6663951
    Abstract: The invention provides a curable two layer effect providing coating system which provides a visual appearance and effect previously obtainable only with a curable three layer effect providing coating system. The two layer effect providing coating system of the invention consists essentially of a first layer consisting of a first coating composition (a), and a transparent second layer applied directly to the first layer and consisting of a second coating composition (b) comprising an effective amount of an interference metal oxide coated mica having a hue shift of at least 100°. In a preferred embodiment of the invention the first coating composition (a) will be tinted so as to match the color of the second coating composition (b) when viewed at an angle of 110° from vertical.

  • Patent number: 5863321
    Abstract: The present invention provides a straight-shade color coating composition comprising a colored metallic flake pigment. The coating composition produces a coating having no apparent gonioapparent effects. The present invention may be used to prepare coatings with increased hiding power at the same color pigment-to-binder ratio or with the same hiding power but lower color pigment-to-binder ratio as compared to previous coating of equivalent hue. The present invention also provides coatings with higher chroma non-pastel colors and cleaner pastel colors as compared to previous coating compositions of equivalent hue.
