Loresco type SC-2® is a dust-free
product and, according to EPA extraction tests, is extremely
pure and complies with regulations governing buried products.
SC-2® mixes easily with water and may be pumped into deep anode
systems. Loresco SC-2® is designed to promote electronic flow
between the anode surface and itself.
Loresco SC-2® is produced specifically for cathodic protection
applications using an exclusive multi-step process. First, a
high quality base carbon with desired characteristics is selected.
Next, this carbon is calcined to a minimum temperature of 1250° C
under exacting and controlled standards. This step results in
semi-graphitized carbon particles with excellent conductivity.
Then, to further improve bulk conductivity, the surfaces of the
individual particles are half-modified to enhance the contact
conductance. This breakthrough in surface alteration ensures
maximum electronic current transfer with positive anode contact.
The surface alteration on the particle surfaces is not easily
removed and stands up to the vigorous application methods in
all field requirements.
Loresco SC-2® has a bulk density of 74 lbs. per cubic foot.
The fixed carbon content is greater than 99.35% by weight. The
bulk density and high fixed carbon content coupled with the assured
low resistivity medium allows for longer groundbed life at a
lower operating cost.
Loresco SC-2® is designed to be used in impressed current cathodic
protection systems, deep or shallow. Specify Loresco SC-2® Super-Conducting
Premium Earth Contact Backfill. For high current installations,
Loresco SC-3® is recommended.
Installation:
Loresco SC-2® has excellent pumping qualities and when agitated
in water, takes on the characteristics of heavy mud. A recommended
mix is seven gallons of water per one hundred pounds. After
installing SC-2®, allow twenty-four hours settling time before
energizing. The modified surface of the carbon particles in
SC-2® will achieve positive electrical contact by settling.
Vibrating or compacting is not necessary.
