Cortec launches corrosion inhibitor for water treatment industries

Cortec Corporation, a specialist in corrosion protection solutions, has introduced a time-release, biodegradable corrosion inhibitor block for water treatment industries as well as being friendly to marine ecosystems.

The CorrBlock is formulated using renewable soybean-based wax and proven Vapour phase Corrosion Inhibitor (VpCI) technology. When immersed in water, the CorrBlock slowly dissolves and releases a calculated amount of inhibitors required for corrosion protection of a system.

The inhibitors in CorrBlock provide multi-metal protection and act as a replacement for chromates, nitrites, and other types of restricted corrosion inhibitors. The VpCIs form a strong monomolecular layer on metal surfaces that protect in all three phases - liquid, vapour, and the vapour-liquid interface.

CorrBlock provides water treatment companies with the ability to incorporate Cortec VpCI technology into their specific applications. In addition to preventing corrosion and pitting, CorrBlock eliminates the need for dosing pumps and tanks for conventional liquid inhibitors as well as protects tools, workpiece, and metalworking machines during downtime. It can be used as a corrosion inhibitor additive in the majority of water treatment programmes and is compatible with most commercially available biocides and antiscalants. CorrBlock is nitrite, chromate, and heavy metal free, and does not cause foaming or promote bacteria growth. It is easily traceable utilising a Molybdenum test kit.

CorrBlock is ideal for open loop re-circulating cooling systems and wastewater systems. The product can be placed in make-up water, cooling tower basin, returned water circuits, or wastewater systems. It is also suitable for use in metalworking machines that are water cooled. This helps protect the tool and parts being machined.

The CorrBlock conforms to NACE Standard Practice RP0487-2000, NACE Standard Test Method TM0208-2008, and MIL-I-22110C
