Aluminum silver paste is a very unique effect pigment, which can be divided into floating type, non-floating type, electroplated silver, imitation electroplated silver, young silver, tin silver, medium flash silver, coarse flash silver, high flash silver, strong flash Silver and so on. It is composed of a very smooth and extremely thin scaly structure. The small particle size has high hiding power, strong coloring power and clear chroma. It combines density and whiteness in one, which can make the surface coating elegant and soft like a mirror. Optical metal effect.
Classification of aluminum paste:
All aluminum pigments can be divided into floating and non-floating types. In grinding engineering, the replacement of one fatty acid by another will give aluminum pigments completely different characteristics and appearance. Because the appearance of each type of aluminum sheet is different from other types, the technical parameters that affect the product application formula and end use will also change according to the desired effect.
1. Floating type
In floating aluminum pigments, the aluminum flakes are oriented around the surface of the paint film to form an opaque silver film. This opaque nature is the main factor that makes floating aluminum pigments an important functional raw material. Floating aluminum pigments are generally Mainly used in roof coatings with high protection requirements, maintenance, anti-corrosion coatings, reflective coatings, imitation plating effect coatings and commercial coatings.
The appearance of floating aluminum pigments will vary depending on the thickness of the particles, and can range from a rough, white appearance to a dull, highly reflective or mirror-like effect. Coarse-grade floating aluminum pigments have a lower hiding power and a rougher structure, but can obtain the whitest and brightest coatings. In contrast, fine-grade floating aluminum pigments have the greatest hiding power, the smoothest structure and highly reflective coatings.
2. Non-floating type
Non-floating aluminum paste has excellent coloring and strong hiding power, and is widely used in industrial coatings, auto parts coatings and decorative coatings; non-floating pigments are uniformly and evenly distributed throughout the paint film. The appearance of the coating film is different from the floating aluminum pigment. Because it can be mixed with a variety of pigments for a variety of systems, it has a unique effect on industrial coatings. However, any pigment or dye must be transparent when used with non-floating aluminum pigments in order to achieve a realistic metallic effect. There are many types of non-floating aluminum pigments, from low to high coloring power, from coarse to fine particles, from white to gray and soft. Non-floating aluminum pigments have a variety of acid resistance levels, which can reduce the impact of industrial smoke, acid rain and other adverse environments on painted parts.
