Is aluminum silver powder a hazardous chemical? Aluminum silver powder is a major category within aluminum pigments, boasting exceptional and unique properties, making it widely used across the powder industry. As a result, market demand for aluminum silver powder remains quite high. But here's the question: did you know that aluminum silver powder is classified as a hazardous chemical? Let’s find out together next!
Is aluminum silver powder a hazardous chemical? Before answering this question, let’s first explore the basic concept of aluminum silver powder. As far as I know, the aluminum silver powder available on the market is primarily made from aluminum powder as the raw material, processed through a ball-milling technique. And the common manufacturing processes on the market mainly fall into two categories: dry ball-milling and wet ball-milling.
Generally, the dry ball-milling process produces floating-type aluminum silver powder, while the wet ball-milling coating process yields non-floating aluminum silver powder. The quality of the resulting aluminum silver powder depends on the wet coating technique: aluminum silver powders coated with fatty acids are typically found in lower-grade products, whereas those coated with acrylic or silica are commonly used in applications requiring excellent acid-alkali resistance and weatherability.
According to what I've learned, aluminum powder falls under Class 4—flammable solids, self-reactive substances, and substances that become flammable upon contact with moisture—and is classified as a Class 1 flammable solid. Its production and sale require obtaining the appropriate licenses; otherwise, it may constitute a violation of the law. Aluminum silver powder, on the other hand, is a deeply processed product derived from aluminum powder, inheriting all of its flammability characteristics. However, it is even more sensitive to specific conditions, making it essential to exercise extra caution during transportation and storage.
