When it comes to color masterbatches, metallic silver particles have always been an indispensable hue—typically produced by incorporating metal-effect aluminum pigments. So, do you know how to choose the right aluminum slurry for making silver-colored masterbatches?
How do you choose aluminum silver paste for silver masterbatch production? When it comes to masterbatches, metallic silver particles have always been an indispensable color option—typically created by incorporating metal-effect aluminum pigments. So, do you know how to select the right aluminum silver paste for making silver masterbatch?
How to choose silver masterbatch and aluminum silver paste? If you want to select a high-quality aluminum silver paste, first you need to understand the key characteristics of silver masterbatch. Silver masterbatch boasts exceptional brightness, coloring power, and dispersibility, making it suitable for various plastics processed via blow molding, extrusion, and injection molding.
Because many metallic effects can only be achieved with aluminum pigments—while other metal pigments either fall short or come at an excessively high cost—aluminum pigments have solidified their position within metal masterbatches. As consumers increasingly demand more vibrant and sophisticated colors, the requirements for metal masterbatches continue to rise.
Currently, the primary requirements for metal masterbatches revolve around aesthetics and performance. In the past, silver tones were limited to a dull silver-gray; today, there’s a growing demand for brighter, more dazzling effects like metallic silver and shimmering finishes. At the same time, performance is increasingly focused on functionality, which naturally leads to higher expectations for aluminum pigments. Beyond enhancing visual appeal, these advancements also aim to minimize—or even eliminate—any negative impact on plastics.
When choosing aluminum silver paste for color masterbatches, it must possess high whiteness and excellent opacity, with a fine and smooth surface. Typically, the oil-based aluminum silver paste is preferred because it contains fewer solvents, resulting in a product that remains relatively dry. This dry consistency makes it easier to mix during processing—since the product isn’t overly sticky—it allows for quicker and more uniform blending with other color pigments and base materials. This not only prevents excessive darkening due to prolonged processing but also minimizes the risk of performance degradation caused by solvent-induced erosion of the plastic substrate. As a result, the oil-based aluminum silver paste is now more favored within the plastic color masterbatch industry.
