Patent number: 7722696Abstract: The invention relates to a coated granular material, wherein the coating is a resin, comprising the reaction producing of at least one compound selected from the group consisting of cardol, cardanol or derivatives or oligomers of these compounds with an isocyanate component, and to a method for the preparation thereof. Water-soluble granular materials are suitable as substances to be coated. Examples of granular substances are fertilizers, crop protection agents, insecticides, pesticides, fungicides, drying agents and mixtures thereof. The substance coated according to the invention has advantageous properties since the resin can be applied in a selective and economical manner to the substrates due to its low tackiness. In particular, coated fertilizer granulates are advantageous in that, with regard to the applied amount of fertilizer, they can provide more nutrients to the plant.Type: GrantFiled: November 27, 2002Date of Patent: May 25, 2010Assignee: Ashland-Sudchemie-Kernfest GmbHInventors: Reinhard Winter, Christian Priebe, Peter Kuhlmann
