Abstract

Procédé d'enrobage de matières actives susceptibles de se dissoudre rapidement dont on cherche à réduire la vitesse de libération caractérisé en ce que l'enrobage est réalisé par compactage d'un mélange de particules solides de matière active et de particules solides d'une matière pseudoplastique. Application particulièrement à la fabication d'engrais inorganiques à libération lente.
