Implications of colorant and carrier particle size ratio
Powder plating is influenced by the physical interaction between the carrier powder and the coloring agent. In general, smaller particle size colorants will achieve a higher coverage. However, the difference in particle size between the carrier and the colorant is an important factor.
To demonstrate the capabilities of our natural VIVAPIGMENTS® we tested three carriers with very different particle sizes: Icing sugar, maltodextrin, and table sugar. As the particle size difference between the carrier and the pigment increases, the coloring power or the plating efficiency at the same color concentration increases as well. The small particle size of our pigments allows for great coloring capabilities with varying particle sizes of the tested carriers.
A technology to increase efficiency in natural color plating
The plating efficiency of the natural VIVAPIGMENTS® was tested relative to the performance of their soluble extract counterparts. Tests were completed at both equal concentrations and at concentrations equivalent to the amount of coloring matter in VIVAPIGMENTS®.
In all cases, the VIVAPIGMENTS® show a higher coloring power than the raw material at the equivalent concentration, and in some cases, it even has a coloring power above that of the raw material at an equal concentration. The increased brightness for a lower cost in use is clearly demonstrated in a powder plating application.
