Abstract: The present invention relates to a method of coating a granular material comprising the steps of (a) providing a granular substance; (b) providing a compound (C) which has at least one ester bond and which is obtainable by reacting a hydroxyl group or epoxy group of a compound (A) with a carboxyl group or anhydride group of a compound (B); (c) providing a compound (D) having at least one epoxy group; (d) reacting compound (C) with the epoxy group of compound (D) to produce compound (E) having an ester bond; wherein the reaction of compound (C) with compound (D) takes place in the presence of the granular material and optionally a curing agent to provide a coated granular material; and wherein the compound (A) has at least one hydroxyl group or epoxy group and is selected from fatty acid ester and fatty acid; and the compound (B) is selected from: compound (B-1) having at least two carboxyl groups; and compound (B-2) having at least one cyclic anhydride group.

Abstract: The present invention relates to a coated granular substance, wherein the coating is obtained by curing a binder, wherein the binder comprises: one or more benzyl ether-type phenolic resins: an isocyanate formulation consisting of one or more isocyanate compounds having at least 2 isocyanate groups per molecule: wherein the binder is further characterized by one or both of the following features: a) the binder contains free phenol and free hydroxybenzyl alcohol, wherein at least about 1.2 parts by weight of free hydroxybenzyl alcohol per 1 part by weight of free phenol is contained in the binder: b) the binder contains free phenol and free saligenin (o-hydroxybenzyl alcohol), wherein at least about 1.1 parts by weight of free saligenin (o-hydroxy benzyl alcohol) per 1 part by weight of free phenol is contained in the binder: wherein the granular substance is selected from agrochemicals.

Abstract: The present invention relates to a coated granular substance, wherein the coating comprises a resin comprising the reaction product of a polyol component and an isocyanate component and cured by the addition of a catalyst, said catalyst comprising a hydroxy group-containing amine compound. Further, the present invention relates to a process for coating a granular substance, comprising the steps of (a) providing a granular substance; (b) providing a polyol component and an isocyanate component; (c) optionally mixing the polyol component with the isocyanate component; (d) adding the mixture of step (c) or the polyol component and the isocyanate component as individual substances to the provided granular substance and producing a coating on the granular substance; (e) adding a catalyst to cure the coating; (f) optionally repeating steps (d) and (e), wherein the catalyst comprises a hydroxy group-containing amine compound.
