International Classification:

F16B 39/02
B05D 3/06
B05C 5/00
B05D 3/02
US Classification:

411 82, 4273722, 427559, 118320, 118642
Abstract:

A fastener suitable for use in airplane manufacture or repair that is coated with a pre-mixed moisture cure sealant. The sealant layer is coated with a frangible moisture barrier that will break apart when the fastener is installed, thus exposing the sealant to atmospheric moisture. Once exposed to moisture, the sealant will begin to cure. Preferred embodiments also provide a moisture indicator that provides a visual indication that the outer moisture resistant layer has been damaged.

Filed:

Feb 15, 2012
Appl. No.:

13/396988
Inventors:

Vijaykumar M. Mannari - Saline MI, US
Assignee:

EASTERN MICHIGAN UNIVERSITY - Ypsilanti MI
International Classification:

C09D 175/04
B05D 3/00
B05D 7/24
C08G 18/06
C08L 75/04
US Classification:

524591, 528 80, 4273855
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.

US Classification:

4284233, 427387, 528 28, 4284258, 524 87, 524 93, 524 83
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.

Vijaykumar M. Mannari - Saline MI, US
Assignee:

EASTERN MICHIGAN UNIVERSITY - Ypsilanti MI
International Classification:

C09D 183/12
C09D 183/06
US Classification:

428414, 523435, 427386, 428418
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).

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.
