How do you use water-based aluminum silver paste? Thanks to its outstanding performance and eco-friendly features, this product is widely employed in various commercial applications—such as sports equipment, electrical appliances, and interior and exterior decorations for buildings—and has been warmly embraced by customers. So, let’s learn together how to properly use water-based aluminum silver paste!
How to use water-based aluminum silver paste? First, let’s get acquainted with water-based aluminum silver paste. It’s a type of metallic pigment primarily used to add a shimmering metallic effect to coatings. The production process mainly involves passivation and silica coating techniques. Among these, the silica-coated version boasts a denser coating layer, allowing the finished paint to remain stable for up to one year. Water-based aluminum silver paste exhibits excellent water resistance, superior weather durability, and is soluble in water with minimal gas emissions. It’s generally suitable for water-based coating systems, and the typical application method is as follows:
I. Before Use: To pre-disperse the water-based aluminum silver paste, dilute it with deionized water (or distilled water/ultrapure water) at a ratio of approximately 1:1. Allow the mixture to soak for 5 minutes, then gently stir until the paste is evenly dispersed. If using tap water instead, it must be left uncovered for at least 24 hours to ensure that any residual chlorine has fully evaporated, as free chloride ions in tap water can severely corrode the silver paste.
II. During Use: Add the dispersed aluminum-silver paste into the resin and mix thoroughly by stirring. Be mindful that the stirring speed should not be too prolonged, as this could cause the coating film of the aluminum-silver paste to peel off. If the coating fails, direct contact with water may lead to hydrogen gas generation or VOC emissions. Therefore, carefully control both the stirring time and speed as much as possible.
