  • Publication number: 20100105817
    Abstract: The invention provides a silane compound that includes a hydrophobic group and a silane ester group linked by a hydrophilic group for use as a surface treatment to an inorganic material, such as a pigment, the silane including a hydrophobic group and a silane ester group linked by a hydrophilic group. The invention includes a coated particle including an inorganic material coated with the silane compound(s) and methods of improving the wettability and/or dispersibility of an inorganic material such as a pigment, wherein the method comprises depositing the silane compounds on the surface of a pigment.

  • Publication number: 20070190343
    Abstract: This invention pertains to UV-absorbing coatings that may optionally be covered with an anti-reflective layer and that are applied to exterior-facing surfaces such as a window or other glass surface that are transparent or translucent. Such coatings are visible to various species of birds, but are generally transparent to humans. The UV absorbing coatings have a silane- or silane-derived chromophore or a combination of a silane- or siloxane-based material and a chromophore, which chromophores absorb UV light at about 300 to about 400 nm. More particularly, the silane- or siloxane-based chromophore is 2-hydroxy-4-(3-triethoxysilylpropoxy) diphenylketone or a derivative thereof.
