  • Publication number: 20220087921
    Abstract: The disclosure relates to aqueous and non-aqueous radiation-curable nail coating compositions having a substantial amount of bio-based material in the corresponding polymeric binder. The compositions incorporate a vinyl-functionalized epoxidized bio-based unsaturated compound, which provides substantial bio-based content, vinyl functionality for curing, and soft segment functionality for ease of removal. The aqueous coating compositions generally include (a) a bio-based polymeric binder including a reaction product between a polyurethane pre-polymer and the vinyl-functionalized epoxidized bio-based unsaturated compound, (b) a photoinitiator, and (c) water. The non-aqueous coating compositions generally include (a) a bio-based polymeric binder including the vinyl-functionalized epoxidized bio-based unsaturated compound, a reactive diluent, and a vinyl functional oligomer, and (b) a photoinitiator. Related methods of forming a nail coating are also disclosed.

  • 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: 9944825
    Abstract: The disclosure relates to curable polysilyl phosphate compounds and compositions as well as related methods and flame-retardant textiles incorporating the same. Curable polysilyl phosphate compounds according to the disclosure include a hydrocarbon moiety comprising at least one phosphate group and more than two hydrolysable silyl groups linked to the hydrocarbon moiety. In some embodiments, the hydrocarbon moiety is derived from spirocyclic pentaerythritol diphosphoryl chloride. The curable polysilyl phosphate compound can applied to a textile substrate and then cured to provide a flame-retardant textile with the cured polysilyl phosphate compound as a coating bonded to the textile substrate.

  • 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. The polyureasil compounds are generally hydrocarbon-based, including multiple urea groups and multiple hydrolysable silyl groups per molecule. The hydrolysable silyl groups can be hydrolyzed and subsequently condensed to provide a networked polymeric structure with siloxane/urea linkages between polyureasil compound precursors to form a cured polyureasil composition useful as a coating for a substrate, in particular an anti-corrosion coating for a metallic 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.
