What are the commonly known facts about water-based aluminum silver paste? Due to its excellent water resistance, weather resistance, and low VOC emissions, water-based aluminum silver paste is widely used in various industries, including water-based baking paints, water-based inks, and water-based architectural coatings. Now, let’s dive into a comprehensive guide covering all the essential knowledge about this versatile material!
According to what I've learned, waterborne aluminum silver paste has evolved alongside the development of water-based coating systems—it’s soluble in water and incredibly convenient to use. Xuyang’s WH series waterborne aluminum silver paste is produced using a dual-coating process involving silica and polymers, resulting in a highly dense coating layer that ensures long-term stability and excellent environmental performance. Now, let me introduce some commonly used knowledge:
1. Instructions for Use: Before using water-based aluminum silver paste, pre-disperse it with water at a 1:1 ratio (you can use purified water or tap water, but ensure it’s left uncovered for 24 hours). Then, gradually add the diluted aluminum silver paste into the water-based base material while continuously stirring. Maintain a steady stirring speed—avoiding excessive haste—and ensure the mixing duration isn’t too prolonged.
2. Storage Time Testing: The sample needs to be placed in a constant-temperature oven at 50°C. If no significant issues such as noticeable bloating or gelation occur within one week, and the coated sample shows no obvious loss of gloss compared to the reference standard, it can be stored at room temperature for up to six months; alternatively, if tested over two weeks, it can be stored for up to one year.
3. Misconception: Is a strong scent unenvironmental? Does adding more water-based aluminum silver paste always enhance the metallic effect? These are all false assumptions. The odor in eco-friendly water-based aluminum silver paste typically comes from the evaporation of coating solvents or additives. Once the addition of water-based aluminum silver paste reaches its upper limit, further increases won’t boost the metallic texture any further.
4. Defect: Currently, the supporting products for waterborne aluminum-silver paste construction are still immature, requiring more manufacturers to jointly advance the development of the waterborne coatings industry.
