Water-based Passivation Bronze Paste
Suitable for Water-based Systems
What Is Water-based Passivation Bronze Paste?
Water-based Bronze Paste products involve adding a certain proportion of water-based additives and solvents to oil-based copper gold powder. Utilizing a multi-layer coating process, the oil-based copper powder is modified to become water-soluble, forming water-based copper gold paste.
It is suitable for alcohol ether systems, ethanol systems, or water-based systems with relatively low water content. In water-based systems, it exhibits excellent dispersibility and a high metallic luster, making it convenient for paint adjustment and color matching.
It’s primarily used in industries such as:
- Water-based coatings (air-dry or low-temperature baking)
- Water-based inks
- Water-based printing
- Water-based immersion coating
- Water-based spray painting

How to Use Water-based Bronze Paste
Start by adding the copper-gold powder under slow stirring. Gradually add a solvent to the powder in fractions, using a ratio of 1:1 or 2:1 (solvent to powder).
Stir at low shear force for about 15 minutes until the mixture becomes paste-like.
Add the required amount of gold-tone oil and stir thoroughly to ensure uniform mixing.
Adjust to the desired viscosity with a solvent.
To prevent the flake-like particles of copper-gold powder from curling and breaking during dispersion, which would reduce the optical effect, it’s best to use a paddle stirrer or disc disperser at medium speed.
Ensuring Every Barrel of Bronze Paste is of High Quality
Prioritizing Quality: Rigorous Testing at Every Stage
- During the ball milling process, test the particle size, hue, and gloss every hour.
- In the polishing phase, test the brightness, hue, and particle size of the copper-gold powder in each transfer barrel, ensuring that the brightness and hue are consistent within the same batch.
- Mixing: For each batch of product, perform sample testing for brightness, hue, and particle size.
Packaging and Storage
Properly stored with a one-year warranty period.
Storage Instructions for Bronze Paste
- Store the gold powder at room temperature and away from light for two years or more. Beyond this period, the brightness of the powder may decrease and turn yellow, affecting the printing quality.
- Gold bars solidified with resin should be stored for half a year. It is recommended that customers use them within three months, as they may become unusable due to denaturation after this period.
- Once made into ink, the quality is best within three months. After opening, ensure the lid is securely closed. Do not exceed 30% of old ink when mixing with new ink for use.
- Products with a particle size above 400 mesh are non-hazardous, while those below 400 mesh are flammable.
- Long-term storage may lead to settling, but the product can be used normally after stirring.
- The product performs best two to three months after production.
