What is aluminum pigment? As life evolves, more and more aluminum pigment products have begun to enter people's daily lives—whether in paints or coatings for furniture. Consequently, public awareness of aluminum pigments is steadily growing stronger. So, what exactly is aluminum pigment? Let the editor briefly introduce you to a comprehensive guide on aluminum pigments. Now, join Xuyang’s editor as we dive into this fascinating topic together!
What is aluminum pigment? Before answering this question, let’s first familiarize ourselves with the basic classification of aluminum pigments. As far as I know, aluminum pigments belong to the category of metallic pigments and are commonly used as fillers in paints and coatings. Thanks to their excellent properties, they can effectively protect and enhance the appearance of products. After carefully analyzing extensive data, I’ve learned that aluminum pigments are primarily divided into three main product categories. Now, let me take you through them one by one!
1. Aluminum Silver Paste: Also known as silver paste or aluminum powder paste, aluminum silver paste is produced using aluminum powder as the raw material. Through a specialized ball-milling process, the aluminum flakes in the paste achieve a uniformly smooth surface, regular shapes, and a tightly controlled particle size distribution, resulting in a paste-like or paste-form product. Based on their performance characteristics, aluminum silver pastes are primarily categorized into water-based and oil-based types. Among the oil-based varieties, the more common ones include floating and non-floating types, typically used in industries such as paints, inks, fiberglass, and automotive coatings. In contrast, water-based aluminum silver paste is specifically designed for use in eco-friendly, water-based material applications—such as waterborne epoxy paints and other related coating industries.
2. Aluminum Silver Powder: Aluminum silver powder is a flake-shaped silver pigment. The pigments used in aluminum silver powder typically have a scale-like structure, which gives the material its metallic luster and excellent shielding properties. Xuyang’s aluminum silver powder is usually produced via a wet ball-milling process followed by coating, resulting in high solid content, stable quality, and outstanding weather resistance. It is commonly used in powder coatings, outdoor decorative products, plastic color masterbatches, and certain ink formulations.
3. Strip-shaped Aluminum Pigment: When it comes to strip-shaped aluminum pigment, let’s start with a brief introduction. Also known as plastic-grade silver strips, this type of pigment is typically produced by removing excess solvents from aluminum-silver paste, adding specific additives, and then extruding the mixture into cylindrical shapes—each measuring 2mm in diameter and 8–10mm in length. Visually, strip-shaped aluminum pigment appears as solid, rod-like particles. It’s environmentally friendly, safe, easy to disperse, and can be stored for extended periods. Commonly used in plastic systems, it finds its primary applications in industries such as home appliances, automotive interiors, mobile phone casings, films, profiles, and color masterbatch production.
