Polyurea/polythiourea compositions comprising the reaction product of a first component comprising isocyanate and a second component comprising an amine, wherein the first component further comprises an isocyanate functional polythioether-polyurethane and/or polythiourethane, and/or the second component further comprises an amine/hydroxy functional polythioether, are disclosed. Methods for using the coating, and substrates coated therewith, are also disclosed.

Polyurea/polythiourea coatings

Disclosed are thioethers, methods for preparing such thioethers, and curable compositions, such as coating and sealant compositions, that include such thioethers. The thioethers can be the reaction product of (a) an alpha, omega dihalo organic compound, (b) a metal hydrosulfide, and (c) a metal hydroxide.

Thioethers, methods for their preparation, and compositions including such thioethers

Disclosed are thioethers, methods for preparing such thioethers, and curable compositions, such as coating and sealant compositions, that include such thioethers. The thioethers can be the reaction product of (a) an alpha, omega dihalo organic compound, (b) a metal hydrosulfide and (c) a metal hydroxide.

Compositions, such as aerospace sealant, coating, and/or potting compositions are disclosed. The compositions include a polythioether and, in at least some cases, can be sprayable and fuel resistant even when substantially free of volatile organic compounds.

Compositions including a polythioether

Epoxy-capped polythioethers, amine/hydroxy-capped polythioethers, and curable compositions of epoxy-capped polythioethers are disclosed.
