Leafing/non-leafing Aluminium pigment

30 Nov 2020

The treated aluminum powder particles can float on the wet film due to their different wettability, forming a uniform layer of pigment on the surface of the paint film, which we call "floating aluminum powder".


Or when it is completely wetted Wet, evenly distributed in the coating film, we call it "non-floating aluminum powder"

The wetting characteristics depend on the lubricating additives used in the grinding process. When stearic acid is used, a floating pigment can be obtained, and when an unsaturated fatty acid (such as oleic acid) is used, a non-floating pigment can be obtained.
The disadvantage of floating type is its poor recoating performance and wear resistance.
Due to its floating properties, the colored metallic effect cannot be achieved.
Since the non-floating type is evenly distributed in the entire coating film, it has
Good wear and corrosion resistance, can be easily recoated.
