Is water-based aluminum silver paste harmful to humans? I believe everyone is familiar with water-based aluminum silver paste—it’s primarily used in waterborne coating systems, which are a new type of environmentally friendly material that contains virtually no toxicity. Moreover, when incorporated into water-based coatings, it doesn’t trigger any violent chemical reactions, making it highly compatible and safe to use. So, is water-based aluminum silver paste truly eco-friendly, and does it pose any risks to human health?
Is water-based aluminum silver paste harmful to humans? I believe everyone is familiar with water-based aluminum silver paste, which is primarily used in waterborne coating systems. As a new type of environmentally friendly material, waterborne coatings contain virtually no toxicity. Moreover, when water-based aluminum silver paste is incorporated into waterborne paints, it doesn’t trigger any violent chemical reactions, making it highly compatible and safe to use. So, is water-based aluminum silver paste truly eco-friendly? And does it pose any risks to human health?
Is water-based aluminum silver paste harmful to humans? Before answering this question, let’s first familiarize ourselves with the basic concept of water-based aluminum silver paste. As far as I know, water-based aluminum silver paste—also referred to as water-based aluminum pigment—is specifically used in water-based metallic coatings. Common production methods include the addition of corrosion inhibitors, passivation techniques using chromic acid, phosphoric acid, or their salts, as well as inorganic silica-coating methods and more advanced approaches like inorganic-organic double-layer coating or hybrid coating processes. Among these, the water-based aluminum silver paste produced via the inorganic silica-coating process features a denser coating layer, which effectively preserves the original hue saturation while also offering superior resistance to acids, alkalis, and enhanced storage stability compared to those made by other methods.
Thanks to its special coating process, water-based aluminum silver paste boasts excellent water resistance, superior weather durability, and remarkably low VOC emissions. However, before applying the water-based aluminum silver paste, it must first be pre-dispersed with water— a non-toxic and readily available liquid. Using this eco-friendly product not only saves energy and protects the environment but also ensures safety for human health. That said, care should be taken during application to control the stirring speed and duration; otherwise, the protective coating could be compromised, allowing aluminum particles to come into contact with air and trigger a chemical reaction that releases harmful gases. As a result, the outstanding environmental benefits of water-based aluminum silver paste have earned widespread recognition from customers in the market.
