Cleveland-based Euclid Chemical has introduced the SENTINEL E Series, a new product line of four galvanic anodes intended to protect reinforcing steel from corrosion. By generating a protective electrical current, these anodes help mitigate the anode ring effect in chloride-contaminated concrete.
Why it matters
The new series provides engineers and contractors with expanded options for cathodic protection in concrete maintenance. These solutions help extend the structural integrity of reinforced concrete by preventing degradation caused by corrosion.
The SENTINEL E Series includes four models containing 65, 105, 160, and 330 grams of zinc. These anodes are engineered for a 10-year service life and are compatible with repair materials possessing surface resistivity up to 50,000 ohm-cm.
The players
Euclid Chemical
Headquartered in Cleveland, this company specializes in the manufacturing of specialty chemical products for the concrete and masonry construction industry.
The details
The anodes utilize galvanized tie wires to establish physical connections to exposed reinforcing steel. This system is designed to provide protection without the need for an external power source, offering a five-year shelf life when kept in unopened packaging.
