Copper Powder — Cold Cast and Patinated Copper Finishes
Allzone Trading supplies copper powder to sculpture studios, restoration contractors, display fabricators and coatings manufacturers across Canada. Copper is chosen where the finish must be warm, and above all where a genuine green or brown patina will be developed chemically after casting — an effect no pigment reproduces. Particle size and surface treatment are confirmed against supplier technical data at quotation.

Technical & procurement detail
Patina is the reason copper is specified+
Because real copper sits at the surface, the piece can be chemically patinated to green, brown or near-black and will continue to age like metal. A copper-coloured pigment cannot be patinated, which is why studios accept the higher material cost.
The powder must be at the surface+
Metal powder loaded through the whole casting is wasted, because only the outer skin is ever seen. Standard practice is a heavily loaded face coat brushed into the mould, backed with unfilled or filled resin, then polished or patinated after demould.
Dust, reactivity and handling+
Fine metal powders present dust and reactivity hazards that differ by metal, and some corrode or patinate on contact with moisture or process chemicals. Handling, storage and finishing chemistry are planned against the supplier's safety data sheet for the exact powder supplied.
Specification options+
Working properties are configurable options within this canonical product, not separate products. Depending on the family, that can include grade, viscosity, mix ratio, pot life and demould time, hardness, colour, particle size or fibre length, and pack format. No configuration is presented as stocked or approved until it is confirmed against the supplier's technical data for the exact material offered. Supplier grade names, factory codes and manufacturer brands are not published here.
What to include in your enquiry+
Tell us the copper finish targeted, resin or coating system, particle size preference, whether patination is planned, volume and delivery location.
Frequently asked questions
Will an unsealed copper finish keep changing?+
Yes. Exposed copper continues to react with the environment. Where the finish must be held at a chosen stage, it is sealed after patination.
Which resin system suits cold casting?+
Polyurethane, epoxy and polyester systems are all used. The choice depends on demould speed, detail and the finishing method, and is decided per product.
Are technical documents provided before ordering?+
Yes. The supplier technical data sheet and safety data sheet for the exact grade offered are provided with the quotation, and the working properties in those documents govern — not any general description on this page.
What quantities are quoted?+
Quantities are reviewed per enquiry, from trial quantities through to pallet and full container programmes for production users and distributors.
