摘要:
A controlled release fertilizer material comprising a particulate plant nutrient surrounded by at least one coating comprising the reaction product of a mixture consisting essentially of a polyol having an equivalent weight from 29 to 150, an isocyanate, a wax, an epoxidized fatty acid triglyceride oil, and optionally, a castor oil.
摘要:
The present invention is directed to a process for coating a substrate in a rotating drum, wherein a pocket is created in a substrate bed into which pocket coating materials are delivered. Also provided is a controlled release product produced according to this process, and an apparatus for carrying out the process.
摘要:
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.
