Backfill LORESCO SC3®
It is a product specifically deisgned for high-performance cathodic protection systems that require low resistivity. Free of contaminants, according to the EPA extraction tests, is extremely pure and meets the regulations for buried products. LORESCO SC3 backfill will mitigate the exchange of fluids between aquifer according to the resultos of tests, using a modified standard method for testing permeability. (API-RO-27)
It is produced specifically for cathodic protection applications, using an exclusive multi-stage process. Firstly, a basic high quality coal is selected then the coal is calcined at 1250°C imder controlled conditions. This step produces a semi-graphitized with an excellent conductivity, then to improve the global conductivity the surfaces of the individual particles are modified to improve the contact conductance. This progress in the surface alteration, ensures a maximum current transfer. Finally, a surfactant is added specially formulated to reduce the tension of the particles and improve the compression underwater.
