ITC 296A: High-Purity Ceramic Top Coat for Maximum Chemical and Deposit Resistance
ITC 296A: High-Purity Ceramic Top Coat for Maximum Protection
ITC 296A is a high-purity ceramic top coat designed to be applied over ITC 100HT (on refractory) or ITC 213 (on metal) to provide an additional layer of protection against deposits from firing gases, molten metal contact, slag attack, and chemically aggressive atmospheres. ITC 296A completes the ITC coating system, and is used in the most demanding applications where maximum protection and energy efficiency are required.
What ITC 296A Does
ITC 296A serves as the outermost layer of the ITC coating system, providing three key functions:
1. Chemical Resistance: ITC 296A resists deposits and chemical attack from firing gases, combustion byproducts, molten metal splash, slag, and corrosive flue gas constituents (including sulfuric acid, hydrochloric acid, and alkali compounds). Its high-purity ceramic composition is chemically inert to the substances that attack bare refractory and metal surfaces.
2. Surface Sealing: ITC 296A creates an extremely smooth, dense surface that resists buildup of deposits, scale, and slag. This smooth surface also enhances the heat-reflective properties of the underlying ITC 100HT, maximizing energy efficiency.
3. Extended System Life: By adding a sacrificial protective layer over ITC 100HT or ITC 213, ITC 296A extends the overall coating system life. The top coat absorbs surface wear and chemical attack that would otherwise degrade the base coat, lengthening the interval between coating maintenance.
Technical Specifications
Application Method: Spray, brush, or roller
Coverage Rate: Approximately 100 sq ft/gallon

When to Use ITC 296A
ITC 296A is specified for applications where the coating surface is exposed to:
• Direct flame impingement — Burner zones, firing ports, and areas near combustion sources
• Molten metal splash or contact — Ladle interiors, furnace hearths, pouring zones
• Slag attack — EAF interiors, cupola linings, any surface exposed to aggressive slag chemistry
• Acid dew point corrosion — Baghouses, scrubbers, ductwork in WTE, power, and cement plants
• Aggressive flue gas chemistry — Alternative fuel environments with alkali chlorides and sulphates
• Deposit-prone environments — Areas where firing gas residue, flyash, or carbon accumulates on surfaces
The Three-Product ITC System
ITC 296A is most powerful when used as part of the complete ITC three-product system:
On Refractory Surfaces:
Layer 1: ITC 100HT (refractory base coat — heat reflection + refractory protection)
Layer 2: ITC 296A (top coat — chemical resistance + deposit resistance)
On Metal Surfaces:
Layer 1: ITC 213 (metal base coat — corrosion + oxidation protection)
Layer 2: ITC 100HT (thermal barrier — reduces heat transfer through metal)
Layer 3: ITC 296A (top coat — chemical resistance + deposit resistance)
The full three-product system on metal (ITC 213 + ITC 100HT + ITC 296A) provides the most comprehensive protection available. It is particularly effective for steel structures exposed to acid dew point corrosion — the primary failure mechanism in baghouses, scrubbers, and ductwork in waste-to-energy, cement, biomass, and power generation facilities.
Documented Results with ITC 296A
TXI Cement, Texas — Baghouse
A 12-compartment baghouse (each compartment 20'x25'x60' high) was corroding from acidic flue gas condensation. The full three-product system was applied: ITC 213 on the metal shell, ITC 100HT as a thermal barrier, and ITC 296A as the top coat. Steel shell life was extended 4–5x. Filter bag and cartridge corrosion was also reduced. This application — using all three ITC products — represents the highest revenue per job in the ITC product line.
Industries Where ITC 296A Is Commonly Used
Waste-to-Energy: Baghouse internals, SDA surfaces, HRSG casings — anywhere exposed to acidic flue gas condensation from waste combustion
Cement & Lime: Kiln burning zones exposed to direct flame, baghouse structures, preheater tower surfaces exposed to aggressive raw meal chemistry
Power Generation: Boiler surfaces, economizers, and air preheaters exposed to sulfur-bearing flue gases and acid dew point corrosion
Steel: EAF delta sections and roofs exposed to slag splash, ladle interiors in contact with molten metal, reheat furnace areas near burner zones
Petrochemical: FCCU cyclone interiors exposed to catalyst erosion, SRU surfaces exposed to sulfur compounds, fired heater burner zones
Biomass: All flue gas path components in biomass combustion facilities, which produce particularly corrosive exhaust due to chlorine and alkali content in biomass fuels
Frequently Asked Questions: ITC 296A
Can ITC 296A be used by itself?
ITC 296A is designed to be used as a top coat over ITC 100HT (on refractory) or ITC 213 (on metal). It is not typically applied as a standalone coating. The base coat provides the primary bonding, heat reflection, and substrate protection, while ITC 296A adds chemical resistance and deposit resistance as the outermost layer.
What does ITC 296A add that ITC 100HT doesn't already provide?
ITC 100HT provides heat reflection and refractory protection. ITC 296A adds a higher level of chemical resistance against deposits from firing gases, molten metal, slag, and corrosive condensation. In environments with aggressive chemistry (acid dew point, alternative fuels, molten metal contact), the top coat provides a critical additional barrier that extends the entire coating system's life.
How much area does one gallon of ITC 296A cover?
ITC 296A covers approximately 100 sq ft per gallon, similar to ITC 100HT on hard refractory. Actual coverage may vary based on surface texture and application method.
Is ITC 296A the most expensive ITC product?
Contact ITC Coatings for current pricing. ITC 296A is a premium product designed for the most demanding applications. The cost of the top coat is typically offset many times over by the extended equipment life and reduced maintenance it provides. For pricing, contact info@itccoatings.com or call 904.759.0152.
