  • Flexible deployable preform
    Patent number: 6485834
    Abstract: 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.

  • Thermosetting composition, uses thereof and a flexible deployable preform comprising the composition
    Patent number: 6187443
    Abstract: 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 alkyl 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 regenerator. 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.

  • Method of using thermosetting compositions with improved latency
    Patent number: 5971071
    Abstract: Thermosetting compositions with improved latency are obtained by addition of a molten aromatic polyamine type curing agent to a liquid epoxy resin followed by cooling the mixture, causing the curing agent to form a suspension of fine particles in the epoxy resin by recrystallisation thereof. The compositions obtained can be used for the manufacture of prepregs with high latency for their use in processes requiring intermediate steps at 80.degree. C. over several hours.
