Anti-Caking Agents for Low Density Ammonium Nitrate (LDAN)

Arkema’s Galoryl^® ATH range of anti-caking agents is applied to explosive ammonium nitrate, also known as low-density ammonium nitrate (LDAN) or industrial grade ammonium nitrate (IGAN) at the end of the ammonium nitrate production process, usually in a rotating coating drum. Our custom-made formulations are designed with high anti-caking and hydrophobic properties. They are designed to adhere to the porous prilled ammonium nitrate’s surface and provide a hydrophobic barrier against moisture. Galoryl^® anti-caking agents are also very effective at impeding the formation of crystal bridges and preventing recrystallization at the substrate surface.

Unlike other more traditional anti-caking agents, Galoryl^® products are neutral, resulting in no ammonia release upon application. Our coatings are available in a range of melt points and can be adapted for specific processes.
