What is the difference between leafing aluminum paste and non-leafing aluminum paste?

In the leafing aluminum paste, the aluminum sheets are aligned near the surface of the paint film to form an opaque silver film. This opaque nature is the main factor that makes the leafing aluminum paste an important functional raw material. Leafing aluminum pastes are generally used in roof coating, maintenance and commercial application coatings that require high protection. The appearance of the leafing aluminum paste can vary according to the thickness of the particles, from a rough, white appearance to a dark, highly reflective or mirror-like effect. The coarse-grained leafing aluminum paste has the lowest hiding power and rougher structure, but it can obtain the whitest and brightest coating. On the contrary, the fine-grained leafing aluminum paste has the greatest hiding power, the smoothest structure and the high reflective coating.

Non-leafing aluminum paste is uniformly distributed in the entire paint film. The appearance of the formed coating film is different from that of leafing aluminum paste. Because it can be mixed with various pigments and is suitable for various systems, it is suitable for industrial coatings. Unique effect. However, any pigments or dyes used with non-leafing aluminum pastes must be transparent, only in this way can they achieve the effect of the realistic metal surface. There are many types of non-leafing aluminum pastes, with color strength from low to high, particle size from coarse to fine, and appearance from white, shiny to grayer and more delicate. There are also acid-resistant products to reduce industrial smoke, acid rain and other adverse environments. The impact on coatings.
