Compositions comprising a combination of low molecular weight prepolymers and high molecular weight prepolymers are disclosed. The compositions are used to fabricate elastomeric articles having high tensile strength and high tensile elongation.

Elastomeric compositions and methods of use

Methods of fabricating seal caps using three-dimensional printing are disclosed. The seal caps are useful for sealing fasteners.

3D printing of seal caps

Methods of making multilayer systems comprising a sealant layer by extruding a coreactive sealant composition are disclosed. The methods can be used to fabricate multilayer systems in which individual layers have different cured properties. Individual layers can also have an inhomogeneous concentration of one or more constituents within a layer. The multilayer systems can be made using three-dimensional printing that facilitate the use of a wide range of coreactive compositions.
