A method of manufacturing indium tin oxide includes sputtering indium and tin from a target onto a substrate, the sputtering including moving the target along a path over the substrate. The indium tin oxide may have a sheet resistance less than 0.5 /. An indium film includes: a first moving target sputtered indium tin oxide layer; a second moving target sputtered indium tin oxide layer on the first moving target sputtered indium tin oxide layer; and a third moving target sputtered indium tin oxide layer on the second moving target sputtered indium tin oxide layer. A transparency includes the indium tin oxide, and a flying vehicle includes the transparency.


A crosslinkable, branched polyester prepared by free radical polymerization of unsaturated polyester prepolymers, wherein the polymerization occurs primarily by reaction of the unsaturation is disclosed. Coatings comprising the same are also disclosed, as are substrates coated at least in part with such coatings.

A waterborne coating composition includes latex particles and a crosslinker. The latex particles can be prepared from a mixture of reactants including: (a) a monomer represented by formula (I), as shown in claim 1(a); where R1 is a hydrogen or methyl group and R2 is a hydrogen, alkyl, or aryl group; (b) a multi-ethylenically unsaturated monomer; and (c) a mono-ethylenically unsaturated functional monomer different from the monomer represented by formula (I), the mono-ethylenically unsaturated functional monomer having a functional group selected from a hydroxyl group, thiol group as shown in claim 1(c), or a mixture thereof, where R9 is a hydrogen, alkyl, or aryl group. A method of preparing waterborne coating compositions and substrates coated with the compositions are also disclosed.

The present invention provides an electroactive optical device including an optical substrate having two opposing surfaces; at least two electrodes spaced one from the other and disposed on the surface of the substrate; and at least one electroactive material layer in contact with the at least two electrodes and the surface of the substrate. The electroactive optical device has variable light transmittance in response to the magnitude of an applied electrical voltage.


Patent
PPG Industries | Date: 2017-02-22

The present invention relates to a primer coating composition that includes, (a) a (meth)acrylic polymer that includes hydroxyl groups, and which has a Tg of at least 30C. The primer coating composition further includes, (b) a polyester that includes hydroxyl groups, and which has a weight average molecular weight of less than 3000, and a hydroxyl value of at least 100. The primer coating composition also includes, (c) a crosslinking agent having at least two isocyanate groups. The present invention also relates to a coated article that includes a repaired area that includes a primer coating formed from the primer coating composition of the present invention. The primer coating compositions, in accordance with some embodiments, provide reduced or minimal ringing defects.
