実験手順
As the urea granules continued to roll a thin layer of the MDI-isocyanuric acid liquid was sprayed onto the urea, amounting to 40.0 grams. One minute time was allowed for the reaction of the MDI with the urea, and then polyol-melamine amounting to 40.0 grams was sprayed on top of the MDI-isocyanuric layer. The layers were allowed 1 minute at 95° C. to react. The melamine and isocyanuric acid reacted to form very fine particles of melamine cyanurate and the MDI and polyol reacted and polymerized to form very strong water insoluble polyurethane resin. The sprays of the MDI-isocyanuric acid, and the polyol-melamine layers were repeated until a total of 240.0 grams coatings were applied. After a final 2 minutes reaction time, the coated urea was cooled to ambient temperature and evaluated.
