Abstract: A method and apparatus for injection molding a metal alloy wherein the alloy is maintained in a thixotropic, semisolid state in a reciprocating extruder (16) at temperatures above its solidus temperature and below its liquidus temperature in the presence of shearing and then injected as a thixotropic slurry into a mold (22) to form a useful product. Following completion of the injection molding stroke, the nozzle (20) of the extruder is sealed by solidifying a portion of the residue of the alloy remaining in the nozzle.

Abstract: Solid epoxy resins having low melt viscosity and high softening points are prepared by partially reacting the aliphatic secondary hydroxyl groups with a monoisocyanate to form pendant urethane groups. These resins are particularly useful as binders in preparing high flow-out, non-sintering powder paints.
