  • Publication number: 20130008346
    Abstract: Complex inorganic titanate pigments with low dopant levels (i.e., less than about 5%) exhibit coloristic and enhanced infrared (IR) reflectance characteristics that make them useful in formulating colors exhibiting high IR reflectivity. This characteristic is becoming increasingly useful as a way to keep exterior surfaces and articles cooler during exposure to direct sunlight. Achieving this can decrease energy (e.g., cooling/air conditioning) consumption and costs. Low-loaded titanates can boost IR reflectivity by 1 to 10% in selected visual color spaces. Paint compositions containing those low loaded titanate pigments and a method for providing a surface with high infrared reflectance utilizing those pigments are also disclosed.

    Abstract: The invention is directed to a process for making screen-printable getter composition comprising: (a) glass frit; and (b) pre-hydrated desiccant material; dispersed in (c) organic medium. The desiccant material is pre-hydrated to reach its saturation level of moisture absorption. The process of pre-hydration can be done by exposing the desiccant in a normal temperature/humidity environment of for example, 25° C. and 50-60% RH. For 24 to 48 hours or up to the time when weight gain (due to moisture absorption) stops increasing. An accelerated hydration process in a chamber with higher than normal humidity level (i.e. 50% Relative Humidity) is also applicable to shorten the time of exposure to fully hydrate the desiccant material.

    Abstract: The invention relates to a translucent or transparent, coloured enamel that contains metal nanoparticles that lost their natural tendency to aggregate with each other, and having a colour essentially provided by the reflection of light. The nanoparticles have lost their natural capability to aggregate with each other due to the application of a coating, or because they have been functionalised electrostatically or using highly sterically hindered entities or using hydrophilic entities located at the surface thereof. The nanoparticles may be gold nanoparticles that impart an intense and deep red to said enamel.

    Abstract: Certain example embodiments of this invention relate to frits or solder glass compounds that include beads, and/or assemblies such as, for example, vacuum insulated glass (VIG) units or plasma display panels (PDPs) including the same. In certain example embodiments, the beads may be hollow glass beads of any suitable shape (e.g., substantially spherical, substantially eye shaped, substantially oblong, substantially square shaped, etc.) with or without evacuated cavities. The inclusion of such beads in a frit material may improve the thermal properties of the bulk fired frit in certain example instances. Additionally, the inclusion of such beads in a frit material may take the place of other more expensive materials in the frit, thereby reducing the costs associated with the fabrication of the assemblies.
