    Abstract: The disclosure provides strengthened products, including strengthened fibrous composite products and methods for making and using same and strengthened particulates, such as particulate fertilizer products, and methods for making and using same. The fibrous composite product can include a plurality of fibers and an at least partially cured strengthening resin. The fertilizer composition can include a particulate core that can include a plant nutrient, at least one coating layer of the strengthening resin, and at least one coating layer of a water insoluble material. The strengthening resin can include one or more aldehyde-based resins and one or more crosslinked resins. The crosslinked resin can include one or more polyamines at least partially crosslinked by one or more symmetric crosslinks and can include one or more azetidinium functional groups.

    Abstract: A process for producing polyurethane coated fertilizer granules having core granules in a rotating drum, wherein the drum has an inlet and an outlet and n application zones arranged along the longitudinal direction of the drum between the inlet and the outlet, n being an integer of at least 2 and wherein each of the application zones is followed by a curing zone. The curing zone after each application zone is arranged to allow an interval of 2-15 minutes, preferably 3-5 minutes, before the application in the successive application zone, wherein the polyol and the isocyanate are applied in the first application zone at a ratio of 0.5-4 wt %, preferably 1-3 wt % of the core granules. The process has the steps of: A) continuously feeding the core granules to the inlet of the rotating drum, thereby providing a flow of the core granules in the direction from the inlet to the outlet, B1) applying a polyol and an isocyanate to the core granules in each of the n application zones, the ratio of hydroxyl groups in the polyol to NCO groups in the isocyanate at the end of each of the application zones being in the range from about 0.9 to about 1.3, B2) reacting the polyol and the isocyanate to form a tack-free polyurethane layer in each of the n curing zones and C) continuously collecting the polyurethane coated fertilizer granules from the outlet.

    Abstract: A coated granule is obtained by coating a bioactive substance-containing granule with a urethane resin obtained by reaction of an aromatic diisocyanate with a polyol mixture containing a polyesterpolyol and a C2-C8 polymethylene glycol, wherein the molar ratio of the polyesterpolyol to the polymethylene glycol is 1:20 to 20:1. The granule is capable of controlling elution of the bioactive substance appropriately, and the urethane resin forming the coating film shows degradability in soil.
