    Abstract: A low-index silica coating may be made by forming silica sol comprising a silane and/or a colloidal silica. The silica precursor may be deposited on a substrate (e.g., glass substrate) to form a coating layer. The coating layer may then be cured and/or fired using temperature(s) of from about 550 to 700° C. A surface treatment composition comprising an organic material comprising an alkyl chain or a fluoro-alkyl chain and at least one reactive functionality comprising silicon and/or phosphorous may be formed, deposited on the coating layer, then cured and/or fired to form an overcoat layer Preferably, the overcoat layer does not substantially affect the percent transmission or reflection of the low-index silica coating. The low-index silica based coating may be used as an antireflective (AR) film on a front glass substrate of a photovoltaic device (e.g., solar cell) or any other suitable application in certain example instances.

Alternatively or in addition, the characteristic period of time is determined by the fact that after it has elapsed, a solvent and/or dilution fluid that is contained in the coating and/or impregnation agent (22) and is to be driven out and/or bound during the heating process has caused fibers in the object (5) to be raised up, so that a secondary treatment of the surface is necessary or desirable.

  • Patent number: 6797333
    Abstract: A treatment for silicone liner coatings after undergoing UV curing. The silicone coats a liner to facilitate its removal from the adhesive attached to a label. The silicone, while a liquid, forms a layer on the liner. UV radiation cures the liquid silicone and causes it to become a coherent, virtually solid layer. Heating the cured silicone layer and allowing it to rest for a short period of time then permits the immediate contact with it of the label's adhesive side without incurring inseparability of the silicone-coated liner from the adhesive-coated label.

  • Patent number: 6759097
    Abstract: Methods and devices for producing images on coated articles are provided. The methods generally comprise applying a layer of magnetizable pigment coating in liquid form on a substrate, with the magnetizable pigment coating containing a plurality of magnetic non-spherical particles or flakes. A magnetic field is then applied to selected regions of the pigment coating while the coating is in liquid form, with the magnetic field altering the orientation of selected magnetic particles or flakes. Finally, the pigment coating is solidified, affixing the reoriented particles or flakes in a non-parallel position to the surface of the pigment coating to produce an image such as a three dimensional-like image on the surface of the coating. The pigment coating can contain various interference or non-interference magnetic particles or flakes, such as magnetic color shifting pigments.
