MULTILAYER HYDROREPELLENT SYSTEMS WITH CONTROLLED RELEASE OF ACTIVE AGENTS IN WATER AND SOIL

The invention relates to formulations for controlled release both in water and in soils, and to the components and processes that enable effective coating of cores in various forms. The technology used for implementing the invention, i.e., multilayer coating of cores with the addition of various additives and active ingredients, enables modulation of release of the active ingredients in the desired times and modes. Release is regulated according to the desired targets. The technology does not use any organic solvent, but is based upon a thermodynamic technology that uses the phase transitions through control of the heat introduced into or removed from the system. The invention uses low-cost compounds, mostly of natural derivation and in any case biodegradable. Hence, the materials and technology necessary for implementing the present invention have a low environmental impact.
