Do you know what water-based aluminum paste is? As the nation’s environmental protection standards continue to rise and people’s awareness of environmental conservation grows stronger, eco-friendly, water-based aluminum paste has gradually begun replacing the traditionally high-pollution solvent-based aluminum paste—becoming the new choice of our time. So, exactly what is water-based aluminum paste? Today, let Xuyang’s editor take everyone on a quick tour to find out!
Do you know what water-based aluminum paste is? As far as we understand, water-based aluminum paste—also known as water-based aluminum silver paste, water-based silver paste, or water-based aluminum slurry—is a common metallic aluminum pigment. It’s primarily used in water-based formulations, including but not limited to water-soluble resin systems, emulsion systems, secondary dispersions, and natural latex systems. Its main purpose is to create stunning decorative effects within the base material, giving coated surfaces a shimmering, metallic finish.
When choosing water-based aluminum paste, many people also need to distinguish between genuine pure water-based aluminum paste and other types. Typically, the primary solvent in truly pure water-based aluminum-silver paste is deionized water. This type of paste can be directly pre-dispersed with water, usually accounting for about 30% of the formulation. Eco-friendly and energy-saving properties are a key feature of water-based aluminum paste. Moreover, water-based aluminum paste produced using silica-coating technology boasts a dense coating layer, excellent water resistance, and outstanding acid- and alkali-resistance, allowing the finished product to remain stable for up to 12 months under proper storage conditions.
The general applications of waterborne aluminum paste primarily span industries such as water-based plastics—like plastic casings for laptops, home appliance housings, and automotive decorative components—as well as water-based metallic paints used in areas like automotive engines, profiles, shipbuilding, piping systems, and automotive touch-up coatings. Additionally, it finds use in water-based glass coatings for products such as cosmetic bottles and wine bottles, and in water-based inks tailored for processes like gravure printing, flexographic printing, and screen printing.
