StackGard™ Coating
Product Description
StackGard™ coating is two component, high temperature corrosion protection system for chimneys of industrial plants.
The flue gases found in cement plants, metal smelters, waste incineration, power generation and oil refineries, contain SO3, SO2, HCl, NOx and dust, they are extremely corrosive and abrasive. StackGard™ has shown
outstanding performance on steel chimneys ducts and fans exposed to this severely aggressive environment
Applications
The main areas of application are on the inside surfaces of steel chimneys connected to:
-
Bag houses, electrostatic precipitators and ducts in cement plants and waste incinerators.
-
Gas scrubbers, ducts and fans in power generation plants and oil refineries.
-
Ducts, filters and scrubbers in copper, zinc or lead smelters.
Performance
StackGard™ has great performance in the steel areas exposed to the hot flue gases of industrial facilities. It protects the steel from corrosion, abrasion and impact at temperatures ranging from ambient up to 255ºC.
StackGard™ will 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
StackGard™ is supplied as two components system that is mixed in a 4:1 volume ratio prior to application. Mixed material is applied by air or airless spray, on a sandblasted, dry steel surface. The material is cured at room temperature after 12 hours into a dry and tough 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 at 100 to 180ºC for few hours(212/356º–F). Typically, this is done using the hot flue gases during the startup of the process.
