What is the general content of gold powder in gold silicone color paste?
The content of "gold powder" (actually copper-zinc alloy powder and other metal pigments) in gold silicone color paste is not a fixed value. It mainly depends on the purpose of the color paste, the required metallic luster intensity and compatibility with silicone. It is usually between 5% and 30%, which can be divided into the following situations:
Low content (5% - 10%)
Applicable scenarios: silicone products that only require "slight metallic luster" or products with high requirements for silicone performance (such as vulcanization speed and flexibility) (such as silicone seals, medical silicone accessories).
Features: The metallic luster is lighter, closer to "gold with pearlescent luster", the effect of gold powder on silicone curing is small (metal powder may interfere with the vulcanization reaction, low content can reduce risks), and the cost is low.
Medium content (10% - 20%)
Applicable scenarios: most decorative silicone products (such as silicone accessories, crafts, silicone mold surface coloring).
Features: The metallic luster is moderate, which can not only show obvious "metallic feeling", but also ensure the compatibility of color paste and silicone (even dispersion, not easy to precipitate), which is a common choice for balancing effect and stability.
High content (20% - 30%)
Applicable scenarios: Products with extremely high requirements for metal texture (such as silicone crafts with simulated metal appearance, silicone parts for stage props).
Features: The metallic luster is strong and close to the reflection of the real metal surface, but it needs to be matched with a special dispersant (to avoid gold powder agglomeration), and it may increase the brittleness of silicone products (compatibility needs to be tested), and the cost is also higher.
