Water-based aluminum paste is a kind of metallic pigment. After special processing technology and surface treatment, the surface of aluminum sheet is smooth and smooth, the edges are neat, the shape is regular, the particle size distribution is concentrated, and the matching with the coating system is excellent. During the grinding process, one fatty acid is replaced by another, giving the aluminum paste a completely different character and appearance, with aluminum flakes in the shape of snowflakes, fish scales and silver dollars.

In the water-based floating aluminum silver paste, the aluminum flakes are aligned near the surface of the paint film to form an opaque silver film. This opaque property is the main factor that makes the floating aluminum paste an important functional raw material. Floating aluminum paste is generally mainly used in roof coating, maintenance and commercial application coatings with high protection requirements. Appearance can 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. Large particle size floating aluminum paste has the lowest hiding power and rough structure, but can obtain the whitest and brightest coating. In contrast, fine-grained floating aluminum pastes have the greatest hiding power, smoothest structure and highly reflective coating.

The water-based non-floating aluminum paste is evenly distributed in the entire paint film, and the appearance of the formed film is different from the floating aluminum paste. Because it can be mixed with a variety of pigments and is suitable for a variety of systems, it is suitable for industrial coating. Has a unique effect. However, any pigments or dyes used with non-floating aluminum pastes must be transparent to achieve that realistic metallic finish. There are many kinds of non-floating aluminum pastes, the tinting strength is from low to high, the particle size is from coarse to fine, and the appearance is from white, shiny to gray and delicate. There are also acid and alkali resistant series products to reduce industrial smoke, acid rain, etc. The impact of adverse environments on coatings. The aluminum paste should be sealed and stored, and it should not be exposed to the air, otherwise its brightness will be affected by oxidation.
