2010 van Belzen Yara 7824565 Urea composition having reduced compressibility
UREA COMPOSITION HAVING REDUCED COMPRESSIBILITY, CAKE FORMATION AND DUST FORMATION, AND PROCESS FOR ITS PREPARATION.
Colorfast urea composition having reduced compressibility, cake formation and tendency of re-crystallization of the urea granulate, wherein the granulate further contains at least two different biodegradable polymers, of which at least one polymer is preferably a polyalkenyl amine compound. The other polymer is preferably polyaspartic acid or polyvinyl alcohol. The invention further relates to a process for the preparation of such a urea composition.
