CorrBlock™

Description: CorrBlock™ is formulated using renewable soybean-based wax and proven Vapor phase Corrosion Inhibitor (VpCI®) technology. When immersed in water CorrBlock™ slowly dissolves and releases calculated amount of inhibitors required for corrosion protection of a system. The inhibitors in CorrBlock™ provide multimetal protection including ferrous metals, galvanized steel, aluminum, and yellow metals. They can replace chromates, nitrites, and other types of restricted corrosion inhibitors. The VpCI®'s form a strong monomolecular layer on metal surfaces that protect in all three phases -- liquid, vapor, and the vapor-liquid interface.

CorrBlock™ provides water treatment companies with the ability to conveniently incorporate Cortec® VpCI® technology into their specific applications. CorrBlock™ conforms with NACE Standard Practice RP0487-2000, NACE Standard Test Method TM0208-2008 and MIL-I-22110C. DOSAGE RATES CorrBlock™ should provide 50 - 100 ppm of inhibitors in a system when immersed. Each CorrBlock™ weighs approximately 400g and is made to treat 4000 liters of running water. The exact amount of CorrBlock™ needed for a system should be determined based on water volume, flow rate, water temperature and water chemistry. When a CorrBlock™ is dissolved a new one can be easily added to the system to provide continued protection.

Application: CorrBlock™ is suitable for open loop re-circulating cooling systems and waste water systems. The product can be placed in make-up water, cooling tower basin, returned water circuits or waste water systems. In typical use CorrBlock™ should be replaced every 1-2 months. CorrBlock™ is suitable for use in metalworking machines that are water cooled. This helps protect the tool and parts being machined. CorrBlock™ is generally compatible with coolant, however testing is recommended.
