DAC-Anode® Distributed Impressed Current Cathodic Protection System
We are proud to distribute the DAC-Anode® system under license on behalf of Corrosion Service Company Limited.
DAC-Anode® is a distributed impressed current cathodic protection (ICCP) anode system for steel reinforced concrete structures. DAC-Anode® has decades of proven service throughout the world, and provides existing structures with an expected service life extension of 10-20 years, at minimal cost to owners and operators. DAC-Anode® forms the anode component of a impressed current cathodic protection (ICCP) system, which is designed to distribute corrosion halting current to steel reinforcement. DAC-Anode® is unique because it comes as a single component coating that can be applied to the surface of the concrete, rather than needing to be embedded in the concrete like other ICCP anode systems, saving time and money while still providing a similar level of protection.
DAC-Anode® Distribution Wire
A tri-metal composite wire is used as the primary current distributor to the DAC-Anode® coating. The platinum-clad anode wire is placed at a typical spacing of 8.2 to 16.4 feet (2.5 to 5 m) on center.
DAC-Anode® WB is a single component, single coat, electrically conductive coating that is applied by brush, roller or spray to the surface of reinforced concrete. Intended for use as an impressed current cathodic protection system anode, DAC-Anode® is designed to distribute direct current to embedded reinforcing steel. Electrical connection to the DAC-Anode® WB coating is accomplished by means of small tri-metal platinum-clad wires embedded into the coating. DAC-Anode® is applied between 8 to 12 mils (200-300 microns) dry film thickness. The material dries in 3 to 4 hours and can be recoated in 4 to 6 hours.
DAC-Anode® Overcoat is a flexible and attractive water-based acrylic finish topcoat that is crack and weather resistant over DAC-Anode® WB. The DAC-Anode® overcoat is applied at 3.5 to 7 mils (87.5 to 175 microns) dry film thickness and is available in an array of colors to achieve an aesthetically pleasing matte appearance. The material is tack free in 2 hours and achieves full cure in 4 to 7 days.
