Layering

Solutions for creating layered pellets

For layering, one or more substances are applied in layers to a starter pellet. The layering process is similar to a film coating process. Often the applied layers are significantly thicker – the weight can increase up to several hundred percent.

Substances can be applied in layers to the core as a solution, suspension or powder. By adding suitable supplementary materials, different characteristics in the active substance layer can be achieved. As a carrier material, neutral pellets of 100 micrometers or larger are used.
