摘要： A cellulose acetate wood filler composition comprises a binder composition and a filler. The binder compositions comprise cellulose acetate, a plasticizer, and at least one organic solvent. The binder compositions may be substantially free, e.g., free of tackifiers. The wood filler compositions may be used in a method of filling a cavity in a substrate. The method comprises applying the wood filler composition to an inner surface of the substrate.

摘要： A cellulose acetate lacquer composition comprises a film forming composition and a diluent. The film forming compositions comprise cellulose acetate, a plasticizer, a secondary film former, and at least one organic solvent. The lacquer compositions may be used in a method of providing a finish or protective cover on at least a portion of a substrate. The method comprises applying the lacquer composition to an inner or exterior surface of the substrate.

摘要： A polymer composition comprising a cellulose ester polymer in combination with a property enhancing agent. The property enhancing agent is combined with the cellulose ester polymer in an amount sufficient to improve at least one physical property. For instance, in one aspect, the melt processing characteristics of the polymer composition can be improved. Alternatively or in addition, molded articles made from the polymer composition can have improved surface characteristics. The property enhancing agent can be an acidic species, such as a diprotic, organic acid.

摘要： A binder composition containing a polyoxymethylene polymer combined with one or more plasticizers is disclosed that is well suited for use in powder injection molding processes. The binder composition can be combined with inorganic sinterable particles and melt blended together to form a feedstock. The feedstock can be fed through an injection molding process to form a green body. The binder composition of the present disclosure can be easily removed from the green body by contacting the green body with one or more acids. The resulting brown body can then be fed through a sintering process for producing three-dimensional articles having complex shapes.
