Abstract
Improvements introduced in the object of the main patent No. 375,779, granted on February 10, 1972, for: "A procedure to reduce the absorption of moisture from urea granules", characterized in that the solid paraffinic component is composed of natural paraffin and synthetic paraffin, the latter having a molecular weight of 500-5000 and a melting point between 85 and 115ºC, in a ratio between 4: 1 and 1: 4, the coating agent being applied at a temperature of the urea granules of 45 -85ºC.
