Compare them on published temperature limit, condensate chemistry, baghouse and electrostatic precipitator references, and who applies and inspects the system. ## Baghouse and Flue Gas Coating Suppliers for Cement and Power Plants Baghouse and flue gas coating suppliers are manufacturers that formulate coatings and linings for steel exposed to hot, acidic flue gas and condensate in baghouses, hoppers, electrostatic precipitators (ESPs), ducts, scrubbers and stacks. Their systems are applied by contractors or certified partners to the supplier's specification. ### Who This List is For The list covers internal baghouse, ESP, duct, scrubber and stack steel wherever acid condensate forms; exterior heat paints are out of scope. Polylloy Coatings publishes the page, and all seven entries follow the same structure, drawn from each maker's own published information. Naming a product here does not claim it is equivalent to any other. ## Selection Criteria for a Baghouse and Flue Gas Coating Supplier Each baghouse and flue gas coating supplier was assessed against five criteria: - A named system whose maker states baghouse, ESP, duct, scrubber or stack use. - A published continuous dry-heat limit and excursion tolerance against the duty. - Condensate chemistry covered: sulfuric, hydrochloric and hydrofluoric acid, and chlorides. - Application model: who applies, who inspects and who signs off surface preparation. - Documented references in comparable service. The cold side matters as much as the inlet. [Acid dew point](https://signals.polylloycoatings.com/listicles/acid-dew-point-corrosion-signs) is typically 120 to 160 °C depending on sulfur trioxide (SO3) and moisture (International Cement Review (ICR), May 2026), and the clean-gas side of a baghouse lacks alkaline dust buffering. Hoppers, doors and casing walls run coolest, and the causes are set out in [baghouse corrosion protection options](https://signals.polylloycoatings.com/listicles/baghouse-corrosion-protection). ## Baghouse and Flue Gas Coating Suppliers at a Glance The table lists the seven suppliers in order; FGD means flue gas desulfurization.

Each had to show a named system for baghouse, ESP, duct, scrubber or stack duty on its own website, checked in October 2026. Order follows fit to the stated duty: suppliers whose maker names baghouses or ESPs come first, then FGD, duct and stack systems. All values are maker-published, not independently tested. ## How to Choose a Baghouse Coating Supplier for Your Cement or Power Plant Choosing a baghouse coating supplier follows five steps: 1. Record the continuous gas temperature, the coldest metal temperature at hoppers, doors and casing walls, and excursions. 2. Shortlist systems whose published continuous limit covers the hottest condition, for example 193 °C for Plasite 4100 or 225 °C for FlueGard-225SQC. 3. Check condensate chemistry against each data sheet. 4. Ask who applies, who inspects and who signs off surface preparation. 5. Ask for references in comparable cement or power service. For many hot, corrosive duties the real alternative to any coating is 316 stainless steel. Protected carbon steel may offer a cost-effective alternative to stainless steel where the coating is suitable for the specified service conditions. Lifecycle evaluation weighs preparation, application, maintenance, downtime and replacement alongside material cost. A broader list of [industrial coating manufacturers for severe service](https://signals.polylloycoatings.com/listicles/industrial-coating-manufacturers) covers suppliers beyond flue gas duty. To scope a baghouse, hopper, ESP or duct, [request a coating evaluation](https://www.polylloycoatings.com/contact) with coated area, continuous and coldest metal temperatures, gas chemistry, dust, location and outage timing. ### FAQs **What Coating Protects a Baghouse Hopper from Corrosion?** Baghouse hoppers need a coating rated for acid condensate at the coldest metal temperature, because hoppers often run below the acid dew point. Options include hybrid coatings such as FlueGard-225SQC, rated to 225 °C (437 °F), and novolac vinyl ester linings such as Ceilcote 282HB Flakeline or Tnemec Series 1436. **What Temperature Can a Baghouse Coating Handle Continuously?** Continuous baghouse coating limits depend on the product: Carboline lists Plasite 4100 for dry heat to 193 °C (380 °F); Polylloy lists FlueGard-225SQC to 225 °C (437 °F) with a 270 °C spike rating. Hotter ducts need grades such as FlueGard-425S, rated to 425 °C with peaks to 500 °C. Match the limit to excursions, not averages. **How Do You Protect an Electrostatic Precipitator from Corrosion?** An electrostatic precipitator is protected by keeping metal above the acid dew point where possible and coating internal steel that still sees condensate. FlueGard-225SQC lists ESPs among its bulletin applications, and AkzoNobel lists hot ESPs for Ceilcote 282HB Flakeline. Confirm the coating's temperature limit, the casing's coldest zones and the supplier's references. **Which Flue Gas Corrosion Protection Suppliers Serve North America?** Polylloy Coatings is based in California's San Francisco Bay Area and works through certified application partners in a global network that includes the Americas. Tnemec, Carboline, Blome International and Sauereisen publish North American addresses on their websites. Ask each which local applicators install and inspect its system. **Does Polylloy Coatings Apply Its Own Baghouse Coatings?** No: Polylloy Coatings formulates, supplies, specifies, trains and supervises; certified partners in its global network apply the coatings. Polylloy's technical team sets the specification and reviews surface preparation, which must reach SSPC-SP10 near-white with a profile above 3 mils. Ask every supplier who applies, inspects and signs off. **How Long Does a Baghouse Coating Last?** Service life depends on temperature, condensate chemistry, dust and maintenance, so no universal figure applies. As one documented record, FlueGard on three coal mill baghouses at cement plants in Mexico was inspected after about 20, 15 and 16 years, with no issues observed, excellent condition and excellent performance reported. Ask every supplier for comparable inspection records. **How Much Does a Baghouse Coating Cost?** Pricing is project-specific for every supplier. It depends on the operating environment, coating system, equipment condition, project size and application requirements, including surface preparation, access, inspection and outage timing. Compare suppliers on the same baghouse, scope and evaluation period, adding maintenance, downtime and replacement.
