Fertilizer Imerys minerals make excellent coating agents preventing caking and dust
Imerys talcs and clays make excellent anticaking agents and inert fillers for fertilizers.
Complex and nitrogen-phosphate (NPK) fertilizers have a natural tendency to cake. Caking can occur during both storage (in bulk or in bags) and in transportation. Imerys talcs and clays make excellent anticaking agents, suitable for both prilled ammonium nitrate and granular fertilizers.
- Prevent fertilizer caking
- Reduce water pick-up
- Prevent the formation of hydrate crystal bridges
- Prevent fertilizer deterioration and dust
Imerys clays are excellent fillers for calcium ammonium nitrate fertilizers.
