Further Information
Use In Cold-Casting / Resin Casting
Add brass powder to castings resins such as polyurethane Fast-Cast resins, polyesters or epoxies for an authentic metallic brass appearance and feel.
Added to the whole of the resin mix, brass 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% brass powder (by weight) would be required to result in a significantly metallic appearance. Higher ratios, up to the limit of pourability, 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 brass particles on the surface of a casting, the brass on the surface will patina (rust) in the same way that a conventional brass product would which means that it will quickly take on the distinctive dull turquoise colour of patinated brass.
All materials are supplied in high quality, re-sealable containers and shipped in protective packaging.

Delivery
Brass Metal Powder is held in stock in the Easy Composites warehouse in Stoke-on-Trent. All orders are dispatched same-day (orders received before 12:00) for next-working day delivery. Because epoxy resin is classified as 'dangerous goods' it can only be sent by specialist carrier.
