  • Patent number: 10118986
    Abstract: The disclosure relates to curable polyepoxysilane compounds and compositions, methods related to curing of such compounds via hydrolysis and/or condensation to form coatings on a substrate, and coated articles formed from the curable polyepoxysilane compounds. The polyepoxysilane compounds are silane-functional precursors and can be used as coatings (or pretreatments) on various substrates (e.g., metals such as aluminum) and provide a substantial improvement in corrosion resistance relative to other anti-corrosion coatings. The silane-functional precursors can be prepared by reaction of functional silanes (e.g., amino-functional silanes or other epoxide-reactive functionalized silanes) with epoxide-containing organic or hydrocarbon compounds and oligomers/polymers thereof (e.g., glycidyl-type ethers or other epoxide-/oxirane-functionalized hydrocarbon compounds), for example including hydrocarbons with one or more aromatic hydrocarbon groups (e.g., in an aromatic polyether).

  • Patent number: 9879140
    Abstract: The disclosure relates to curable polyureasil compounds, methods related to curing of such compounds via hydrolysis and/or condensation to form coatings on a substrate, and coated articles formed from the curable polyureasil compounds.

  • Patent number: 9837181
    Abstract: The disclosure generally relates to a dispersion of nanoparticles in a liquid medium. The liquid medium is suitably water-based and further includes an ionic liquid-based stabilizer in the liquid medium to stabilize the dispersion of nanoparticles therein. The stabilizer can be polymeric or monomeric and generally includes a moiety with at least one quaternary ammonium cation from a corresponding ionic liquid. The dispersion suitably can be formed by shearing or otherwise mixing a mixture/combination of its components. The dispersions can be used to form nanoparticle composite films upon drying or otherwise removing the liquid medium carrier, with the stabilizer providing a nanoparticle binder in the composite film. The films can be formed on essentially any desired substrate and can impart improved electrical conductivity and/or thermal conductivity properties to the substrate.

  • Patent number: 8952093
    Abstract: The disclosure relates to water-dispersible polyurethane polymers as well as related polyurethane dispersion (PUD) compositions including the same, methods of making the same, methods of using the same, and articles coated with the same. The water-dispersible polyurethane polymer includes hydrophobic oligomeric polyether soft segments that include 1,2-di-substituted oxyethylene repeating units. The 1,2-di-substituted oxyethylene repeating units are derived from unsaturated fatty acid esters, such as from a distribution of epoxidized vegetable oil fatty acid esters subjected to a ring-opening polymerization process for oligomeric polyether polyol formation. The water-dispersible polyurethane polymer further includes hard segments common to other PUD compositions.

  • Patent number: 8921477
    Abstract: Nanolatexes comprising functional monomers and methods for making nanolatexes. Compositions comprising between about 3:97 and 90:10 (w/w) nanolatex particles to conventional latex particles. Because of the particle size differences between the conventional and nanolatexes, the nanolatexes may distribute themselves advantageously amongst the conventional latexes during coalescence, resulting in films having unexpected properties. In particular, when the average particle size of the conventional latex is about six times larger than the average particle size of the nanolatex, a composition comprising a ratio of 1 conventional latex particle for every 25 nanolatex particles results in unexpectedly strong (large Young's modulus) and smooth (high specular gloss) films.
