Controlled release fertilizer employing epoxidized fatty acid triglyceride oil as a coating additive
A controlled release fertilizer material comprising a particulate plant nutrient surrounded by at least one coating comprising the reaction product of a mixture comprising a polyol, an isocyanate, a wax and an epoxidized fatty acid triglyceride oil.
A controlled release fertilizer composition and methods to produce the controlled release fertilizer composition are described. The controlled release fertilizer composition comprises a water soluble fertilizer core that is coated with a polymeric layer, intermediate layer, and a sulfur layer. If desired, the sulfur layer can be coated with an outer water-insoluble layer.

Thiol ester compositions, methods of making the thiol ester compositions, and methods of using the thiol ester compositions are provided. In some embodiments, the thiol ester compositions include thiol esters, hydroxy thiol esters and cross-linked thiol esters. The thiol ester composition can be used to produce cross-linked thiol esters, sulfonic acid-containing esters, sulfonate containing esters and thioacrylate containing esters. The thiol ester compositions can be used to produce polythiourethanes. The polythiourethanes can be used in fertilizers and fertilizer coatings.
The present invention relates to a process for producing a coated product comprising: (a) coating a substrate with a coating material to form a coated substrate; and (b) stabilizing the coated substrate to form the coated product; wherein the operating parameter of substrate-substrate contact and coated substrate-coated substrate contact differs between step a) and step b), such that in step b) the contact is minimized. An apparatus is also provided.
