Nano grade particles are round in nature. How to make each particle remain and exist independently and still maintain the nano state when using the nano particles applied to final application environment is a big technology challenge in the industry today.
The core of Eisvogel nanotechnology is that it ensures each pigment particle is coated and isolated in its original appearance and size, and prohibiting the agglomeration in the process of product realization. The original shape and size of nano particles is well protected in the chosen polymer.
