  • Patent number: 7795328
    Abstract: Disclosed is a randomly moldable thermosetting paste containing small mineral balls, an inorganic binder or a mixture of such binders, and a fiber moiety. Said paste is characterized in that hollow mineral microballs are used. The paste which cures starting at room temperature is suitable for use as a fire-resistant and heat-insulating material that is provided with great inherent stability in the cured state. The inventive paste is suitable for the production of inexpensive low-density molded parts. Moreover, the invention makes it possible to dispense with the use of organic solvents such that the paste can be used directly by the user.

  • Patent number: 7601426
    Abstract: An intumescent coating in the form of an initially liquid coating which cures to a solid and adheres to a substrate. The coating includes a flexible thermosetting epoxy, such as diglycidyl ether of bisphenol-A (DGEBA), with an aliphatic amine curing agent, expandable graphite flakes with reagent chemicals that react upon heating and decompose into gaseous products, and fumed silica. In the presence of heat or flame, an intumescent layer develops at the coating surface, insulating the substrate. The coating is found to add intumescent characteristics which provide heat resistant and fire retardant qualities.
