FlueGard® Series
Product Description
FlueGard® coatings are two component polymeric alloy material with temperature range 225 to 425 Celsius. Main use is for corrosion protection in the flue gas section of industrial plants. The flue gases found in cement plants, metal smelters, waste incinerators, power generation and oil refineries, contain SO3, SO2, HCl, CO2, NOx and dust. They are extremely corrosive and abrasive.
FlueGard® has further improved the outstanding performance on carbon steel and stainless-steel surfaces.
Applications
The main areas of application are on the inside surfaces of:
-
Bag houses, electrostatic precipitators and ducts in cement plants and waste incinerators.
-
Flue Gas Desulfurization scrubbers, ducts and chimneys in power generation plants and oil refineries.
-
Ducts, filters and stacks in copper, zinc or lead smelters and battery recycle plants.
Performance
FlueGard® is the best-known performance protecting the steel areas exposed to the hot flue gases of industrial facilities. It is resistant to corrosion, abrasion and impact at temperatures from ambient up to 225ºC. Most important, it will not fail by delamination as other high temperature coatings. FlueGard® will also resist severe chemical and salt corrosion in industrial and marine environments due to its tough impervious thermoset nature and a strong chemical bond to the substrate.
Installation
FlueGard® is supplied as a 100% solids two component system, it is mixed in a 4:1 volume ratio prior to application. Mixed material is applied by airless spray or roller on a sandblasted, dry steel surface.
The material cures at room temperature after 12 to 24 hours, into an elastomeric coating. At this stage it can be inspected for thickness and integrity and any defect can be recoated.
Once the coating inspection is satisfactory, the final cure is performed by heating from room temperature to 140/180ºC (284/356ºF) and holding for few hours. Typically, this is done using the hot flue gases during the startup of the process. Also, can be done with an external heat source.
