Are you familiar with the industry standards for waterborne aluminum silver paste? As an essential component of water-based aluminum pigment coatings, this product has gained increasing attention as more people become environmentally conscious. However, when it comes to waterborne aluminum silver paste, industry standards are absolutely indispensable. So, do you know about these crucial standards? Let’s learn together!
Are you familiar with the industry standard for water-based aluminum silver paste? According to our research, this type of paste is water-soluble and boasts excellent water resistance, superior weatherability, and eco-friendly, energy-saving features. It’s widely used in various industrial and commercial products, including sports equipment, electrical appliances, and interior and exterior decorations for buildings. The "Industry Standard for Water-Based Aluminum Silver Paste" was spearheaded by Xuyang, with participation from multiple leading companies in the industry. This standard outlines the specific requirements for water-based aluminum silver paste, as well as guidelines for sampling, testing methods, inspection procedures, and labeling, packaging, and storage practices. Here’s a brief overview:
1. Requirements: The product must exhibit good water dispersibility without any flocculation, maintain a mass fraction of non-volatile substances ≥50% at 105°C, and produce a coating film with excellent silver-white metallic luster, decorative appeal, and smoothness—qualities closely matching the appearance of the film prepared using the supplier’s reference sample.
2. Sampling (Testing Water Dispersibility): Take a representative sample of the test product according to GB/T 3186. Weigh 1 g of the sample, place it in a 100 ml beaker, and add approximately 3 g of alcohol-ether solvent for pre-dispersion. Then, carefully measure 10 ml of water and pour it into the beaker, stirring thoroughly with a glass rod. Observe whether any flocculation occurs in the dispersion within the beaker.
3. Testing items: Water dispersibility, 105°C non-volatile content, coating film appearance, residue on sieve, hydrogen evolution, storage stability, iron content, lead content, and the combined content of steel, iron, lead, and zinc, among others;
4. Inspection, Packaging, and Storage Rules: Inspection results shall be determined using the rounded-value comparison method specified in GB/T 8170. Packaging should be done in iron drums, stored in a well-ventilated, dry environment, protected from direct sunlight. The product must be kept isolated from water, acids, alkalis, oxidizing agents, and ignition sources, and stored away from heat sources.
That’s all for today’s introduction by Xuyang’s editor on "Do You Know the Industry Standards for Water-Based Aluminum Silver Paste?" We hope this was helpful—see you next time!
