Further Information
Use In Cold-Casting / Resin Casting
Add copper powder to castings resins such as polyurethane Fast-Cast resins, polyesters or epoxies for an authentic metallic copper appearance and feel.
Added to the whole of the resin mix, copper powder will increase the density of a casting (making it feel heavier) as well as its thermal conductivity (making it feel colder). Alternatively, it can be added in higher ratios to only a thin surface layer by slush-casting or rotational-moulding, giving a very metallic surface to a casting that can then be back-filled with unfilled resin.
Mix Ratios
A ratio of at least 50% copper powder (by weight) would be required to result in a significantly metallic appearance. Higher ratios, up to the limit of pour-ability, will yield a more impressive metallic appearance and feel.
When adding metallic powders to polyester or vinylester resin systems it is important to catalyse the resin prior to adding the metal powder so as to avoid any adverse reaction (rapid oxidisation) of the metal powder by the catalyst.
Such oxidisation or other adverse reactions are unlikely to occur with polyurethane or epoxy resins but it may still be a good idea to mix the resin and hardeners together before adding the metal powder.
Revealing the Appearance
After casting, the metallic appearance will not be clear or vivid because the metal particles will be obscured behind a thin layer of resin. To reveal the metallic appearance, the casting can be rubbed with an abrasive pad or wire-wool.
Patinating (Rusting)
After exposing copper particles on the surface of a casting, the copper on the surface will patina (rust) in the same way that a conventional copper product would which means that it will quickly take on the distinctive turquoise colour of patinated copper.

Metal powders, contrary to expectations are poor conductors. Firstly, in a metal powder a significant proportion of the material is air. You have a lot of particles which you would expect to be touching each other, which they are, but the point of contact is possibly only a fraction of the surface of each particle (whether it’s spherical or irregular) so you have lots of contact points, but they are quite small, and what you actually have is a lot of gaps, so you have only a fraction of the metallic “continuity” (I couldn’t think of a better word) through the sample that you would expect. Secondly with all metal powders there is a tiny layer of oxide on the surface of each particle, as you would have on the surface of a solid metal, this will give a small amount of resistance on say a solid piece of metal, but multiply that by the thousands/millions of particles in the sample and this resistance becomes significant, building to the point where the metal apparently doesn’t conduct. In reality it does, but not much. There is usually enough conductivity for, say, antistatic properties, but that’s about it. I would think that in a resin, you probably lower the conductivity even more as you will start blocking some of the already tiny contact points. There are metal powders produced for conductivity applications, such as silver coated coppers or even silver or gold may be used (higher conductivity and less oxidation), but as you can imagine they become very expensive.
