Loresco offers a full line of earth contact backfills and related products which are designed and produced exclusively for the corrosion industry. All Loresco backfills begin with high-quality carbons that are calcined to exacting standards. These carbons are further processed to enhance various properties depending upon the specific application or field conditions.
RS-3® Rapid Sinking and Super Conducting Earth Contact Backfill
Loresco RS-3® is a surface modified, blended, and sized carbon backfill with surfactants. Loresco RS-3® is the newest and most innovative super conducting earth contact backfill in the Loresco product line. RS-3® combines the characteristics of superior low resistivity and high bulk density with a remarkably rapid sinking ability to provide the latest in conductive carbon backfill technology.
SC-3® Super Conducting Earth Contact Backfill
Loresco type SC-3® is designed specifically for demanding anode systems which mandate a low resistivity medium. SC-3® is the finest earth contact backfill in the Loresco line. A dust-free carbon product, sized and surface modified with wetting agents added. Dramatically lowers system operating resistivity in both surface and deep anode systems by 40%. Recommended for installations requiring highest quality electronic contact between anode and backfill.
