Fertilizer composite and method of reducing dust formation
A fertilizer composite comprising a simple or complex granular solid fertilizer and a coating covering the fertilizer granules, the coating comprising from 10-90 wt % of a first wax component comprising linear alpha olefin wax having a carbon number in the range of from 20 to 100 and a congealing point in the range of from 40 to 80° C.
1. A fertilizer composite comprising a simple or complex granular solid fertilizer and a coating covering the fertilizer granules, the coating consisting essentially of a first wax component comprising a linear alpha olefin having carbon numbers of 26 or greater and a congealing point of from 40 to 80° C.
2. The fertilizer composite of claim 1 wherein the granular solid fertilizer is selected from monoammonium phosphate—MAP, diammonium phosphate—DAP, superphosphate (a mixture of calcium acid phosphate and calcium sulfate), triple superphosphate (calcium acid phosphate), ammonium sulfate, potassium phosphate, potassium sulfate, potassium nitrate, urea, or ammonium nitrate.
3. A fertilizer composite comprising a simple or complex granular solid fertilizer and a coating covering the fertilizer granules, the coating consisting essentially a first wax component comprising a linear alpha olefin having carbon numbers of 26 or greater and a congealing point of from 40 to 80° C.
and a second wax component comprising a linear alpha olefin wax including C20, C22 and C24 alpha olefins and a congealing point of from 20 to 50° C.
4. The fertilizer composite of claim 3 wherein the granular solid fertilizer is selected from monoammonium phosphate—MAP, diammonium phosphate—DAP, superphosphate (a mixture of calcium acid phosphate and calcium sulfate), triple superphosphate (calcium acid phosphate), ammonium sulfate, potassium phosphate, potassium sulfate, potassium nitrate, urea, or ammonium nitrate.
5. A method of reducing dust formation, the method comprising coating a fertilizer particulate with a coating, the coating consisting essentially of a linear alpha olefin wax having carbon numbers of 26 or greater and a congealing point of from 40 to 80° C.
6. A fertilizer composite comprising a simple or complex granular solid fertilizer and a coating covering the fertilizer granules, the coating consisting essentially of a first wax component comprising a linear alpha olefin having carbon numbers of 26 or greater and a congealing point of from 40 to 80° C.; a second wax component comprising a linear alpha olefin wax including C20, C22 and C24 alpha olefins and a congealing point of from 20 to 50° C.; and a third component comprising one or more paraffinic waxes, one or more Fischer Tropsch waxes, one or more microwaxes, one or more waxes derived from palm, soy, or tallow sources and/or one or more base oils.
