What factors determine the quality of water-based aluminum silver paste? China's scientific research capabilities are steadily growing stronger, and its international standing is rising year by year—so much so that "Made in China" is gradually becoming a new global standard. Xuyang Group is a high-tech enterprise specializing in the production of aluminum silver paste, equipped with a highly skilled and professional technical team. So, what exactly influences the quality of our water-based aluminum silver paste? Let us now delve into the answer to this question!
What factors determine the quality of water-based aluminum-silver paste? To better understand this issue, we first need to clarify what water-based aluminum-silver paste actually is. Typically, water-based aluminum-silver paste—also known as water-based silver paste, water-based aluminum paste, water-based silver powder paste, or water-based aluminum powder paste—is gaining widespread attention alongside the development of waterborne coatings.
Since metallic aluminum is a reactive amphoteric metal element, it readily reacts with water, acids, and bases, releasing hydrogen gas and causing the "popping" or "bubbling" phenomenon. Currently, most water-based coatings on the market are slightly alkaline, and some even have very high acid values. The key factors determining the quality of waterborne aluminum-silver paste include the manufacturing method, hue and brightness intensity, as well as its resistance to acids, alkalis, and shear forces—and, of course, its shelf life. Next, let’s delve into the specific methods used to produce waterborne aluminum-silver paste.
1. Addition of corrosion inhibitors and passivation methods using chromic acid, phosphoric acid, or their salts
The advantages include low production costs, short processing time, and excellent product brightness—effectively preserving the original hue and luminosity of the oil-based silver paste. However, the disadvantages are that the coating may be uneven or even absent altogether, resulting in poor acid and alkali resistance of the silver paste, as well as a very limited or even nonexistent shelf life.
2. Inorganic Silica Coating Method
The advantages include being closer to the original hue and brightness of oil-based silver paste, strong acid- and alkali-resistant properties, and a relatively dense coating layer—resulting in finished paints that typically can be stored for 6 to 12 months. The drawback, however, is the relatively high price.
3. Inorganic-Organic Double-Layer Coating or Hybrid Coating Method
The advantages include excellent acid and alkali resistance as well as outstanding shear resistance; however, the disadvantages are a complex coating process, high costs, long production cycles, and significant color hue loss.
