  • SUBSTRATE WITH HARD ANTIREFLECTIVE COATING
    Publication number: 20250034037
    Abstract: A coated substrate includes a substrate and a multilayered antireflective coating built up from layers having different refractive indices on at least one side of the substrate. Layers having a relatively high refractive index and layers having a relatively low refractive index alternate and at least one layer having a relatively low refractive index is composed of a composition X containing silicon oxide and zirconium oxide. A proportion of zirconium in a metallic and semiconducting component in the composition X is 0.2% to 10% by weight.

  • SPILL RETENTION MECHANISMS FOR COOKTOPS AND OTHER SUBSTRATES
    Publication number: 20200317560
    Abstract: The present disclosure describes spill retention mechanisms for cooktops and other substrates. The spill retention mechanisms can hinder the movement of liquids primarily due to the physical attributes of the mechanisms, unlike hydrophobic mechanisms which hinder movement primarily due to the chemical attributes of the hydrophobic material.
