  • Patent number: 6443996
    Abstract: A decorative dye colorant for use on various types of natural stone, such as granite, marble, limestone, and soapstone. The colorant is formed by mixing a solvent soluble dye with a suitable solvent, such as a ketone or an alcohol to form a dye solution. The solvent enables the dye to penetrate easily into the pores or openings located in the surface of the stone to color the stone so as not to mar the appearance of the surface of the stone. The dye is resistant to removal or discoloration, but may be removed by extended contact of certain chemicals with the dye. To permanently prevent the removal of the dye, a sealer is applied over the dye to prevent any such materials from contacting the dye. The sealer is comprised of an aliphatic urethane mixed with the alcohol xylol that also includes ultraviolet light resistant properties to prevent the dye from fading over time.

    Abstract: The invention relates to tantalum (V) nitride pigments with improved color values compared with predisclosed products, a process for producing such pigments and their use. According to the invention, pigments having an a* color value in the CIE Lab system of equal to/greater than 45, in particular equal to/greater than 50, are obtainable by after-treating a tantalum (V) nitride produced in a known manner in a salt melt at 100 to 600° C., in particular 300 to 500° C., in the course of 1 to 100 minutes, in particular 5 to 60 minutes. Preferably, the after treatment is carried out in an alkali-metal nitrate melt. The pigments can be used to color plastics and paints, and also enamel, glass and porcelain decorations.

  • Publication number: 20010015155
    Abstract: A water-permeable solid material is provided having water-permeable properties together with strength for use as paving materials by effective use of so-called “clinker ash” generated from thermal power plants and the like. In addition, in order to prevent abrasions when pedestrians fall in the case in which a solid material is used as a paving material, a water-permeable solid material is provided having a smooth surface in which the surface irregularities is reduced as small as possible. Coal ash is used as an aggregate, and the particles of the coal ash are tightly bound with each other by a small amount of cement using the pozzolana property of the coal ash. In addition, an inorganic material is interposed between particles of the coal ash, which is used as an aggregate, so as to improve the strength while ensuring voids.

  • Patent number: 6270562
    Abstract: A filler material comprising a fibrous material and one or more forms of surface-modifying particles for use in dental composites and dental restorations. The surface-modifying particles are bonded to the fibrous material to increase the surface area of the fibrous material and improve the bonding properties of the fibrous material to enable it to better bond to a resin matrix material in a dental composite. In accordance with the present invention, the fibrous material possesses a lower melting temperature than the surface-modifying particles. The surface-modifying particles and the fibrous material are heated to a temperature below the softening temperature of the fibrous material but at a temperature and time sufficient to soften the surface of the fibrous material in order to bond the surface-modifying particles thereto.

  • Patent number: 6221147
    Abstract: Bismuth manganese oxide pigments are used as additives to various materials such as plastics, plastic or organic coating compositions, glass and ceramic coating compositions, and the like. The bismuth manganese oxide pigments preferably comprise Bi2Mn4O10 crystallized in the orthorhombic crystal structure. The pigments possess improved reflectance characteristics, particularly in the IR region, and may reduce IR-induced heat buildup.

  • Patent number: 6187070
    Abstract: Production of a finished fabric backing for use in the production of a coated abrasive is performed using a dual cure system comprising a radiation curable binder and a thermal initiator in which polymerization is initiated by the use of radiation until the exotherm produced raises the temperature of the formulation to the activation temperature of the thermal initiator. Thereafter the polymerization continues under the influence of the thermal initiator alone.
