DuPont cellulosic and poly(ethylene oxide) products can be used in a variety of agricultural applications such as seed coatings.
- ETHOCEL™ ethylcellulose polymers are highly insoluble in water and can therefore be used as a binder and film-former for water-insoluble coatings used for controlled release of active ingredients to aid germination. ETHOCEL™ dissolves in a wide range of solvents such as aromatic hydrocarbons, natural oils and others. They make ideal thickeners for non-aqueous formulations.
- METHOCEL™ cellulose ethers are water-soluble polymers, used as an adhesion aid for seed coatings. They act as a binder in granulation and can help compatibilize liquid solutions, emulsions and suspensions. They are also frequently used in spray of pesticides and fertilizers to help control drift or delay evaporation.
- POLYOX™ Water-Soluble Resins help reduce spatter and mist formation of aqueous formulations. This property can make it easier to apply insecticide, pesticide and herbicides by spraying without fogging or drift to adjacent areas. Water soluble packaging are becoming an increasingly popular delivery system for crop protection products. Such packaging provides the end-user with a premeasured quantity of the product to be applied, prevents direct contact with the substance, and minimizes measurement error. POLYOX™ combines high water-solubility with thermo-plasticity making POLYOX™ useful to manufacture this type water-soluble packaging.
