  • Patent number: 9657194
    Abstract: Disclosed herein are stable organosiloxane coating compositions comprising a blocked isocyanate silane and at least one polyol that provide abrasion resistant coatings for transparent polymer substrates. The cured coatings also have excellent adhesion to the polymer substrates. In accordance with certain embodiments, the disclosed coating compositions, which when cured on the substrate, provide formable, weatherable, anti-fog, or combinations of formable, weatherable, or anti-fog organosiloxane coatings. Also disclosed herein are articles comprising coatings cured from such coating compositions, and processes for making the coating compositions.

  • Publication number: 20120115109
    Abstract: A dental material is provided that exhibits a color change upon or after mixing or contacting components of the composition. The composition includes an acidic component in one part, and a basic component in another part that upon contact with the acidic component initiates a chemical reaction thereof that alters the pH of the composition. An acid or base sensitive color change agent is present in the composition that registers the change in pH by changing color as the pH changes.

  • Publication number: 20100248190
    Abstract: A method for temporarily widening a gingival sulcus is provided using an uncured composition comprising a polymerizable monomer having at least one ethylenically unsaturated group, a photo polymerization initiator, a fine inorganic powder, and an astringent. The uncured composition is inserted within a gingival sulcus to be widened, and the composition is thereafter irradiated in situ to polymerize the composition. The result is a rubbery material that is easily removable from the widened sulcus.
