What are the production processes for aluminum silver paste? As demand for aluminum silver paste continues to grow, the market is virtually saturated. However, ongoing improvements and adjustments in manufacturing processes have led to the emergence of various production techniques within the industry—each with its own unique characteristics. So, do you know what these production processes for aluminum silver paste are? Let us now briefly introduce a few of them!
What are the production processes for aluminum silver paste? To answer this question, we first need to understand what aluminum silver paste actually is. As far as I know, aluminum silver paste is a type of metallic pigment that typically undergoes special processing techniques and surface treatments. These processes ensure the aluminum flakes have a smooth, even surface with neatly aligned edges, regular shapes, and a tightly controlled particle size distribution—resulting in excellent compatibility with various coating systems.
Typically, there are four main production processes used to manufacture aluminum silver paste: the addition of corrosion inhibitors method; the chromic acid, phosphoric acid, or their salt passivation method; the inorganic silica coating method; and the inorganic-organic double-layer coating or hybrid coating method.
The first and second types largely retain the original hue and brightness of the oil-based silver paste, but they either lack a coating altogether or have an incompletely dense coating, resulting in poor acid and alkali resistance for the silver paste.
The process that has gained popularity in the market involves using silica-coated aluminum silver paste, where the dense silica coating preserves the original hue and brightness of the oil-based silver paste while offering excellent resistance to acids and alkalis. Additionally, the finished product can be stored for more than a year. Typically, the coating process employed for resin-coated silver pastes is an inorganic silica-coating method, which ensures that each aluminum flake is enveloped by a specialized polymer layer. This unique polymer gives the aluminum silver paste exceptional weather resistance, along with outstanding acid-alkali tolerance, voltage resistance, and unparalleled adhesion properties.
That’s all for the editor’s introduction to the "various production processes of aluminum silver paste." We hope this has been helpful. Thank you for reading, and we wish you a wonderful day ahead!
