How can you tell the difference between floating silver and sinking silver in aluminum silver paste? Hello, it’s Xuyang’s editor here again! Today, we’re addressing a question that many customers have when purchasing aluminum silver paste: What’s the difference between floating silver and sinking silver? As aluminum pigments continue to advance rapidly, their quality keeps improving. Naturally, when customers buy aluminum silver paste, they often inquire about its applications and performance characteristics. At Xuyang, our oil-based aluminum silver paste is categorized into two types—floating silver and sinking silver—based on its intended use. However, some customers still struggle to distinguish between the two. So, let’s dive in and learn how to easily differentiate between floating silver and sinking silver in aluminum silver paste, courtesy of Xuyang’s expert editor!

 How to distinguish between floating silver and settled silver in aluminum silver paste
How can you distinguish between floating silver and settled silver in aluminum silver paste? According to what I've learned, floating silver—also known as floating-type aluminum silver paste—is distinguished from sinking silver, which is referred to as non-floating-type aluminum silver paste. With growing market demand, both floating and non-floating aluminum silver pastes have become incredibly popular aluminum pigments, widely favored by customers.
Floating aluminum silver paste typically features aluminum flakes positioned near the surface of the paint film. These flakes align in a directional manner, forming an opaque silver-colored layer. This opacity is one of the key factors that make floating aluminum silver paste a crucial functional raw material. The paste is primarily used in roofing coatings where high protection is required, as well as in maintenance and preservation coatings, anti-corrosion paints, reflective coatings, decorative coatings mimicking plating effects, and commercial-grade paints. Additionally, due to its exceptionally high surface tension, floating aluminum silver paste cannot be wetted by the base material, causing it to float on the surface of the wet coating film. This unique effect is achieved through the use of stearic acid as a lubricant.
Silver paste, on the other hand, boasts excellent tinting strength and superior opacity, making it widely used in industrial coatings, automotive parts coatings, and decorative paints. Unlike floating-type aluminum silver paste, non-floating aluminum silver paste is evenly and parallelly distributed throughout the entire paint film, resulting in a coating appearance that differs from its floating counterpart. Non-floating aluminum silver paste can be prepared either by adding highly polar substances or drying agents to floating-type aluminum silver paste, or by incorporating special lubricants during the grinding process. Because non-floating aluminum silver paste is fully wetted, it can be uniformly dispersed across the entire coating film.
That’s all for today’s introduction by the editor on "How to Tell Apart Floating vs. Sinking Aluminum Silver Paste." We hope this was helpful—see you next time!
