For water-based aluminum silver paste, its visual effects can generally be categorized into several major types: imitation electroplating effect, fine white effect, and shimmering effect. Each of these effects corresponds to different industry requirements. Today, we’ll focus on how to select water-based aluminum silver paste with a fine white effect.

For water-based aluminum silver paste, its visual effects can generally be categorized into several major types: imitation electroplating effect, fine white effect, and shimmering effect. Each of these effects corresponds to different industry requirements. Today, we’ll focus on how to select water-based aluminum silver paste with a fine white effect.

First, from its literal meaning alone, we can see that its defining characteristics are being fine and white. The “fine” refers primarily to the relatively small particle size of water-based aluminum silver paste, which in turn results in better opacity. As for “white,” it’s due to the smaller particle size of the aluminum powder—while the metallic texture isn’t particularly strong, the paste does exhibit a bright, white appearance. Therefore, if you’re looking for a fine, white-type water-based aluminum silver paste, you’ll generally need to select it from among water-based aluminum silver pastes with smaller particle sizes.

There are several issues that require particular attention during the screening of fine, white water-based aluminum-silver paste:

I. Dispersion of Water-Based Aluminum Silver Paste

Since many customers, in order to ensure the performance of the base material, would like to directly add water-based aluminum silver paste into the base material without going through the pre-dispersion step. In such cases, the dispersibility of the water-based aluminum silver paste becomes particularly critical, and the quality of its dispersion will directly affect the performance of the silver flakes. Therefore, this aspect absolutely deserves everyone’s attention.

II. Stability of Water-Based Aluminum-Silver Paste

Since fine, white water-based aluminum silver paste is inherently difficult to produce, it’s crucial to conduct stable thermal storage tests during the selection process to ensure that the product’s shelf life meets its specified requirements. The testing method is relatively simple: take a sample of the prepared water-based silver-pigment paint and place it in a恒温 oven set at 50°C for thermal storage testing. Typically, after testing for about 7 to 14 days, if no obvious signs of swelling or gelation are observed when compared to the reference standard, the product can be stored at room temperature for 6 to 12 months.
