1. COUTFILL EEM Permanent Earth Enhancement is completely physical earth enhancement. It choose the carbon element of electrolyte powder conductive material instead of the corrosive electrolyte, thus can improve corrosion resistant. The electrolyte will not be restricted by the acid , the alkali , salt , temperature , damp condition. 2. COUTFILL EEM earth enhancement material is non-dissolving good conductor.It won't reduce electric conductivity as the water table drops or the weather is arid and won't lapse because too much rainwater, either. 3. COUTFILL EEM earth enhancement material keeps function good. It can improve the electric potential distribution, thus reduce the voltage of stepping forward, protect the personal security. 4.COUTFILL EEM Permanent Earth Enhancement is able to bear high-temperature and severe cold , able to bear high pressure strike. It is long-term steady and effective. The service life is greater than 30. 5. COUTFILL EEM Permanent Earth Enhancement is light black solid powder under the normality. It is nonpoisonous and free-pollution. It has no peculiar smell. Its dry powder proportion is 0. 85-0. 95, the thin degree of dry powder <200 eyes. More detail of COUFILL
