Are you familiar with the precautions for using water-based aluminum silver paste? According to our research, aluminum silver paste is a metallic pigment added to coatings that enhances the metallic shimmer effect of the coating on the substrate. Based on the solvent used, aluminum silver paste can be categorized into oil-based and water-based types. The principle behind water-based aluminum silver paste stems from the reactive nature of aluminum—a metal with amphoteric properties—which readily reacts with water, acids, and bases, releasing hydrogen gas and causing phenomena such as bubbling and swelling. In fact, when using water-based aluminum silver paste, it’s important to pay attention to the following key points:

1. Dispersion

Before use, water-based aluminum silver paste must generally undergo preliminary dispersion to ensure that it is fully dispersed. Taking our Xuyang water-based aluminum silver paste as an example, we recommend using deionized water or antifouling agent (ethylene glycol butyl ether) as the solvent prior to application.

2. Storage Environment

To ensure the shelf life of water-based aluminum silver paste, it is recommended to store it in a dry, well-ventilated warehouse. If possible, maintain the room temperature at a relatively suitable level. For products that have already been unpacked and have some remaining quantity, promptly reseal the opening to prevent prolonged exposure to the outside environment, which could affect product performance.

3. How to place an order

Due to the unique nature of our industry, we recommend that customers who are new to our products first obtain a small sample for testing before placing an order. During the testing process, in addition to paying attention to the product’s visual appearance, it’s also essential to conduct necessary tests on its performance, such as stability. Under no circumstances should you skip these critical tests simply because they seem cumbersome. Once you’ve completed the performance testing with the sample, you’re free to place your order at any time.

4. Regular self-inspection

Whether you’re a new or existing customer, after ordering raw materials, we recommend promptly taking samples and conducting all necessary tests to ensure that this batch of products is free of issues within the paint formulation. Only then should you proceed with large-scale production.
