Environment-friendly water-based Bronze Powder | Bronze Pigment Powder
Description:
Bronze Powder use copper, zinc as the main raw / materials, through smelting, spray powder, ball grinding and polishing process of extremely slight flake metal powder, also called copper zinc alloy powder, commonly known as gold powder.
Characteristics:
Our water-based bronze powder use silica and organic surface modifiers double-coated, make the film has uniform thickness, close-grained capability and do not influence metallic luster. During its long term storage, water or alkali material is hard to permeate the coat, and no corrosion and color change. The water-based bronze powder is widely used in the water-based coatings system.

Application:
The water-based Bronze Powder is widely used in plastics, silica gel, printing, textile printing, leather, toy, home decoration, cosmetic, crafts, Christmas gifts and so on.
Instructions for use:
1.Bronze Powder has good float ability, and the float ability will decrease if add to any wetting agent or dispersing agent.
2.If want to adjust the float ability or Bronze Powder, can decrease the float ability properly (add 0.1-0.5% citric acid), but it will reduce the metallic effect.
3.If adjust the applicable viscosity and drying time cannot achieve ideal optical effect (the Bronze Powder particles do not well directional arranged), can add a few surface lubricant and leveling agent.
4.Generally, Bronze Powder has good re-dispersion. Once precipitated, can add some anti-settling agent or thixotropic agent (< 2.0%), like bentonite or fumed silica, etc.
5.The Bronze Powder and its products should be stored in a dry place at room temperature. Close the drum’s cover of Bronze Powder soon after using it, in case of oxidative deterioration.
