Do you know the difference between water-based aluminum silver paste and oil-based aluminum silver paste? As the automotive industry’s demand continues to grow, so do the requirements for automotive coatings—and many customers are gradually becoming more familiar with the aluminum silver pastes needed for these applications. However, a small number of people still struggle to distinguish clearly between water-based and oil-based aluminum silver pastes. So, what exactly are the differences between them? Let Xuyang’s editor provide a simple introduction!
Do you know the difference between water-based aluminum silver paste and oil-based aluminum silver paste? According to what I've learned, aluminum silver paste is created by ball-milling aluminum powder, while water-based aluminum silver paste is produced through a secondary processing step applied to the oil-based version. Generally speaking, the main differences between the two lie in their ease of handling and cost. Now, let me give you a brief introduction to both.
We all know that silver-aluminum paste is typically categorized into oil-based aluminum-silver paste and water-based aluminum-silver paste. Its main components are flake-shaped aluminum particles and petroleum solvents, and it comes in a paste-like consistency. Aluminum-silver paste is characterized by its exceptionally smooth and even surface, highly uniform particle size distribution, relatively regular shape, and outstanding reflective properties. When combined with transparent, colorful pigments, it produces a truly dazzling and visually stunning decorative effect.
Typically, water-based aluminum silver paste, compared to oil-based aluminum silver paste, is a silver paste that dissolves only in water, whereas the oil-based version dissolves exclusively in oils. The key difference between the two lies in their material properties: water-based aluminum silver paste, due to its unique composition, boasts higher environmental benefits—but it can be somewhat challenging to handle and tends to have slightly weaker performance. In contrast, oil-based aluminum silver paste is easier to work with, delivers superior performance, and comes at a more affordable price.
