Flexible deployable preform

摘要

A thermosetting composition with a glass transition temperature of at least 100 C. comprises at least one epoxy resin formed from at least one polyepoxide containing at least two epoxy groups in its molecule and at least one aromatic polyamine containing at least two primary amino groups in its molecule, at least one alkanoyl substituent containing 1 to 12 carbon atoms located in the position alpha to one of the amino groups. The molar ratio of the amine to the epoxide is such that each amine group corresponds to 1.6 to 2.6 epoxy groups. The composition also includes a flow controller. The composition can be used as a protective coating for any metallic or non metallic surface. The invention also concerns a flexible deployable preform comprising the composition
