Abstract: An improved feedstock material for D-RIM type PIM processes to manufacture parts. The feedstock includes metal or powders or a mixture thereof which is coated with a surfactant to improve rheology and keep the powder from inhibiting a catalytic reaction which occurs during the process. A condensation thermosetting resin is mixed with a latent catalyst and added to the mixture. A modifier can also be added to the mixture, as can a latent catalyst which is a metal salt such as copper triflate. The constituents when mixed together form a uniform feedstock which is injected into a heated mold. The mixtures cures in the mold and a partial debinding occurs. When the part is removed from the mold, it is sintered. Addition of the copper triflate adds significantly to the green strength of the part, and allows parts to be made at least as quickly as parts made from other feedstock materials. Hydrating the copper triflate greatly increases the shelf life of the feedstock.
