Bronze powders and pastes
We sell two distinctly different products within the Bronze range.
The first is an uncoated Bronze which will oxidise and which is quite dull in colour.
The second is Bronze powders and pastes which are coated, and are leafing grades. These powders are
bright in colour and are available in different colours and grades.

Origin of Bronze Pigments
Bronze powders are also called bronze flakes or bronze pigments, and are issued from the milling process of the bronze granules.
Like the bronze granules, the colour obtained depends on the percentage of zinc added to the melt process. The colour obtained will be:
-> metallic red or copper (100% copper),
-> lighter metallic red or Pale Gold (90% copper - 10% zinc)
-> lighter metallic gold or Rich Pale Gold (80% copper - 20% zinc)
-> metallic gold or Rich Gold (70% copper - 30% zinc).
The metallic colour of Bronze Powders
The metallic colour obtained from the milling process gives a very brilliant, mirror-like effect to the powders and this mirror-like effect makes the bronze powders suitable for a wide range of applications ranging from paints, coatings and plastics, to printing inks and many others.
Depending on the application, a smaller or finer particle size will be required. Grades of coarse particle size are more brilliant than grades of fine particle size, while grades of fine particle size will have a higher coverage capacity in cm²/gram
