20080207797 | Anti-Fogging Coating Solution and Anti-Fogging Article - An anti-fogging coating solution comprising a homopolymer of a repeating unit derived from an ethylenic monomer having a hydroxyl group in the side chain or a copolymer of the above repeating unit and a repeating unit derived from an ethylenic monomer having an epoxy group, alkoxycarbonyl group, carboxyl group, amido group or amino group in the side chain as a resin component. A film formed from the coating solution of the present invention has excellent scratch resistance, initial anti-fogging property and anti-fogging retainability. | 08-28-2008 |
20090018236 | ANTIHAZING AGENT FOR NONCRYSTALLINE CYCLOOLEFIN RESINS, RESIN COMPOSITIONS, AND OPTICAL ELEMENTS - An antihazing agent for noncrystalline cycloolefin resins which can inhibit the hazing of the resins due to fine cracking caused by environmental change, particularly, environmental change from high temperature and humidity atmosphere to ordinary temperature and humidity atmosphere without losing the characteristics inherent in the resins to keep the transparency of the resins and inhibit the light transmittance thereof from lowering; noncrystalline cycloolefin resin compositions containing the agent; and optical elements made from the compositions. A compound component containing a metal rosinate as the main component is used as the antihazing agent for noncrystalline cycloolefin resins. It is particularly preferable that the antihazing agent further contain one or more members selected from the group consisting of alkali metal salts, alkaline earth metal salts, and Group 12 metal salts. | 01-15-2009 |
20100234489 | COATING COMPOSITION FOR WIPER BLADE AND WIPER BLADE MANUFACTURED THEREFROM - Disclosed is a coating composition for a wiper blade, which includes a silicone-based wax, a silicone oil and a solid lubricant so that the silicon-based wax in a liquid phase dissolved in the silicone oil coexists with the solid lubricant for extended time periods. Also, a wiper blade is provided, which has a rib including a coating layer formed from the coating composition, so that upon operation of the wiper blade, components of the coating layer dissolve out of the surface of the coating layer and are then transferred onto a windshield due to friction between the wiper blade and the windshield, thereby forming on the surface of the windshield a water repellent film which is hard and has outstanding durability. | 09-16-2010 |
20100267862 | METHODS OF PREVENTING FROST FORMATION AND FACILITATING THE REMOVAL OF WINTER PRECIPITATION RELATIVE TO A WINDSHIELD AND COMPOSITIONS FOR USE THEREIN - Disclosed herein is a winter precipitation barrier composition, comprising: a retaining agent, a solvent, and optionally, an auxiliary component, such as a rheology/viscosity modifier, surfactant, detergent, foaming/defoaming additive, humectant, dye, colorant, fragrance, or a combinations thereof. In one embodiment, the retaining agent comprises a primarily hydrophobic monomer or a hydrophilic monomer. | 10-21-2010 |
20120245250 | ANTI-FOG COATING COMPOSITION - Provided is an anti-fog coating composition that rarely suffers from blushing when applied and dried even under high-humidity conditions and that can be heat-cured even at low temperature in a short time and form a coating film that exhibits excellent tight adhesion to a substrate and excellent heat resistance and anti-fog properties. The anti-fog coating composition comprises (A) a copolymer prepared from a monomer mixture of a monomer (A1), a monomer (A2) and a monomer (A3); (B) a basic compound such as amines; and (C) a surfactant such as anionic surfactants. The monomer (A1) is a vinyl monomer that has an N-methylol group or an N-alkoxymethylol group. The monomer (A2) is a vinyl monomer that has a sulfonic acid group. The monomer (A3) is an alkyl(meth)acrylate monomer. | 09-27-2012 |
20150344725 | HYDROPHILIC ANTI-FOG COATINGS - The present invention relates to hydrophilic anti-fog coatings. In particular, the coatings use two types of nanoscale particles, colloidal silica and porous organosilicate micelles, in a polyurethane matrix. The invention is an anti-fog coating for optically clear substrates (polycarbonate, polyurethane, nylon, polyester and other clear plastics) without the need for a primer and glass or oxide substrates with an additional primer layer, comprising monosized colloidal silica nanoparticles and porous organosilicate micelles in a polyurethane matrix. The silica is preferably 1-5% by weight and the micelles are loaded at 0.1 to 10% volume percentage by volume. The polyurethane prepolymer is dissolved at 10-40% by weight in a mixture of tertiary amyl alcohol and diacetone alcohol to customize for dip, flow or spray coating processes | 12-03-2015 |
