The present invention relates to a binder composition comprising an aliphatic polyester polymer; an ethylenebisamide wax; and a guanidine wetting agent. The composition may also contain an additive which accelerates or extends debinding of the binder composition, and to a method for forming a sintered part by powder injection molding, including the steps of forming a green composition comprising a binder and an inorganic powder, wherein the binder is a composition comprising an aliphatic polyester polymer, an ethylenebisamide wax, and a guanidine wetting agent, and may further include an additive which accelerates or delays completion of debinding of the binder; melting the composition; injecting the composition into a mold for a part; heating the part to a temperature at which the binder decomposes; heating the part to a temperature at which the inorganic powder is sintered.
