Product information "Brass powder, 40µm, rich gold, flaky / platelet-shaped, gold bronze metallic pigment, stabilized"
This brass powder is specially manufactured for optical and functional applications. It is coated with 1.5 % oleic acid, which stabilizes it.
In plastic processing, it delivers outstanding effects with HDPE, LDPE, ABS, or even PVC. When producing masterbatches, special care must be taken to minimize shear forces and exposure to high temperatures. Otherwise, both factors could negatively impact the final optical result.
This powder is also ideal for use in paints, coatings, 2K resins, and screen printing. A pigment-to-binder ratio of 5/100 is sufficient for an optically high-quality finish. The result is an impressive gold-metallic effect, giving the surface the appearance of polished brass sheet.
- Screen printing: Mesh size should be at least three times larger than the powder’s D90 value.
- Aerosol spray cans: The powder’s D90 value must be at least three times smaller than the nozzle diameter.
- Paints/coatings: Avoid high-speed agitators, as mechanical stress could damage the particles and diminish the metallic effect.
Typical chemical and physical specifications:
- Base metal purity: 99.9 %
- Alloy composition: ~70 % Cu, 30 % zinc
- Shade: rich gold
- Laser diffraction: D10 18.5 µm | D50 42.8 µm | D90 84.0 µm
- Bulk density: ~0.95 g/cm³
- Hiding power: ~2600 cm²/g
- Acetone-soluble components: 1.5 % (oleic acid)
