Product Description
SANAGUREX, a polyurethane-based controlled release fertilizer coating, forms a shell on the fertilizer substrates and the polymer coating allows nutrients to be gradually released into the soil while preventing them from flowing outward. This coating system is composed of two components: polyol and isocyanate. The coating system is a polyurethane resin containing approximately 60% biomass raw materials. Both components are solvent-free. The fertilizer particles are coated in a drum mixer at room to moderate temperatures.
