摘要： PROBLEM TO BE SOLVED: To provide coated particle powder which is composed of metal powder and a silicone resin and is suitable for the production of a molding or the like.SOLUTION: The coated particle powder is composed of a coated particle including: a metal particle; and a coating material made of a thermosetting resin coating the surface of the metal particle. Then, the coating material is composed of a silicone resin (specified silicone resin) having a trifunctional type molecular structure with the main chain in which Si bonded with three Os is siloxane-bonded (-Si-O-Si-bonded) and side chains made of a methyl group or a phenyl group, and having the average molecular weight (Mz1) of ≤10,000. In the specified silicone resin composing the coating material, crosslinking and condensation polymerization hardly progress, and it exhibits characteristics similar to those of a resin raw material. For example, its molecular weight distribution is hardly changed before and after the coating, and it is softened till the minimum viscosity reaches ≤100 Pa s, and further reaches ≤10 Pa s when temperature is increased from its solid state.
