Beschreibung
Zusammenfassung:	A resin for use in molding, sintering, or extruding finIshed parts, the resin comprising a plurality of polymeric particles and a coating of at least one additive covering each of the polymeric particles. The method of preparing the resin comprises the steps of combining at least one additive, a plurality of polymeric particles, and at least one liquid to form a suspension; and removing at least a portion of the liquid from the suspension to thereby form at least a partial additive coating on each polymeric particle. L'invention concerne une résine à utiliser dans le moulage, le frittage ou l'extrusion de pièces finies, ladite résine comprenant une pluralité de particules polymères et un revêtement d'au moins un additif recouvrant chacune desdites particules polymères. Ce procédé de préparation de la résine consiste à mélanger au moins un additif, une pluralité de particules polymères et au moins un liquide afin de former une suspension, et à éliminer au moins une partie du liquide de la suspension, en vue de constituer au moins un revêtement additif partiel sur chaque particule polymère.
