  • Reversible polymer gel binders for powder forming
    Patent number: 5602197
    Abstract: Thermoplastic binder compositions comprising a high molecular weight polymer component and a molten wax component are compounded with sinterable ceramic or other inorganic powders. Upon cooling, a thermally reversible gel is formed in the binder by the gelation of the polymer in the molten wax. Ceramic batches comprising these binders behave as shear-thinning and thermally reversible gels. They exhibit substantially improved dewaxing performance and, preferably, extensibility sufficient for sheet reforming processes.

  • Composite article composed of rigid components with different coefficients of thermal expansion
    Patent number: 5139857
    Abstract: There are disclosed a method of bonding components having substantially different coefficients of thermal expansion, and composite articles thus produced. The components are bonded with the cured product of an adhesive formulation composed essentially of a hydrogenated epoxide, an acrylate or blocked isocyanate end-capped urethane oligomer and an amine curing agent. Optionally, the formulation may contain an accelerator, an epoxy diluent and other minor ingredients.
