How to Tell Professional Water-Based Aluminum Silver Paste Apart? As industrial technology continues to advance, the demand for coatings is growing steadily. Different brands and grades of coatings have varying requirements for pigments. Interestingly, water-based aluminum silver paste also comes in different qualities—so how can you distinguish between the good ones and the not-so-good ones? Let’s learn together! **How to Identify High-Quality Water-Based Aluminum Silver Paste** Before we dive into that, let’s first understand what water-based aluminum silver paste actually is. Commonly known as water-based aluminum paste, water-based silver powder paste, or water-based aluminum powder paste, this product can be directly pre-dispersed using water. One of its key features is being environmentally friendly and energy-efficient. Moreover, the water-based aluminum silver paste produced with silica-coating technology boasts a dense protective layer, offering excellent water resistance as well as superior acid and alkali resistance. As a result, the finished product can maintain stability for up to 12 months under proper storage conditions. **Key Factors to Distinguish Professional Water-Based Aluminum Silver Paste** To identify high-quality water-based aluminum silver paste, here are several important aspects to consider: 1. **Product Requirements**: Water-based aluminum silver paste is widely used in applications like water-based coating printing and dyeing, water-based industrial paints, water-based automotive coatings, and water-based plastic paints. Each application has unique demands regarding particle size distribution, dispersibility, and other properties. Therefore, the first step is to clearly define your specific needs for the product. 2. **Visual Inspection**: High-quality water-based aluminum silver paste should exhibit no signs of deformation or swelling on its packaging. When examining the paste internally, pay attention to its dryness—drier paste typically indicates a higher solid content. 3. **Performance Testing**: To assess its quality, you can test the paste by diluting it with a 5% sodium hydroxide (NaOH) solution. Good-quality water-based aluminum silver paste will remain stable for at least 10 minutes without reacting with the alkali. In contrast, lower-quality products may produce significant bubbles within just a few seconds. Additionally, genuine high-quality paste can be easily diluted directly with water, whereas some inferior versions rely on solvents for coating, making them much harder to thin out in water. 4. **Certification**: Reputable water-based aluminum silver pastes come with relevant environmental certification documents, such as VOC compliance reports and comprehensive testing results for 18 heavy metals. These certifications ensure the product meets stringent safety and eco-friendly standards. That concludes our guide on "How to Distinguish Professional Water-Based Aluminum Silver Paste."
