How can you distinguish high-quality water-based aluminum silver paste? With the advancement of industrial technology, the demand in the coatings industry continues to grow. Different brands and grades of coatings have varying requirements for pigments—and surprisingly, water-based aluminum silver paste also comes in good and bad qualities. So, how do you identify top-notch water-based aluminum silver paste? Let’s find out together with a guide from Xuyang editor!
How can you identify high-quality water-based aluminum silver paste? Before we dive in, let’s first understand what water-based aluminum silver paste actually is. Commonly known as water-based silver paste or water-based aluminum powder paste, it can be directly pre-dispersed using water. An important feature of this product is its eco-friendly and energy-saving nature. Moreover, the water-based aluminum silver paste produced with a silica-coating process boasts a dense coating layer, excellent water resistance, and outstanding acid- and alkali-resistant properties, allowing the finished product to remain stable for up to 12 months. To distinguish high-quality water-based aluminum silver paste, focus on the following key points:
1. Product Application Requirements: Waterborne aluminum silver paste is widely used in water-based coating printing and dyeing, water-based industrial paints, water-based automotive paints, and water-based plastic coatings. Different applications have varying requirements for particle size distribution, dispersibility, and other factors; therefore, the first step is to clearly define the type of product you need.
2. Physical Inspection: High-quality water-based aluminum silver paste should show no deformation or swelling of the packaging. When examining the paste internally, observe its dryness or wetness— the drier the paste, the higher its solid content.
3. Chemical Testing: Take a 5% dilution of the NAOH solution for testing. Since lead reacts with alkali, high-quality water-based aluminum silver paste will remain stable for 10 minutes without reacting, whereas lower-quality paste typically starts producing abundant bubbles within just over ten seconds. Additionally, premium water-based aluminum silver paste can be directly diluted with water, while some other formulations are coated in solvents, making them difficult to thin out even when added to water.
4. Professional Production Certificates: High-quality water-based aluminum silver paste comes with relevant environmental monitoring certificates, including VOC tests and reports detailing the detection of 18 heavy metals, among other certifications.
