Case Study:
Chimney Stack Protection Against SO₂ sulphur dioxide
Chimney Stack Protection Against SO₂ sulphur dioxide gas at 110°C (230°F).
A chimney stack in Poland, crucial for emissions management, needed protection against rapid corrosion caused by continuous exposure to sulphur dioxide (SO₂) gas at 110°C (230°F). To combat this harsh environment, a durable protection solution was essential to prevent further deterioration and extend the structure’s lifespan.
Resimac’s coating system was chosen for its proven resilience and ability to withstand extreme temperatures and corrosive conditions.
Resimac’s Chimney Stack Protection Solution: sulphur dioxide (SO₂) gas at 110°C (230°F).
- Surface preparation by abrasive blasting to SA2.5 standard with a 75-micron profile.
- Stripe coating of weld joints with 206 Ceramic HTA Fluid applied at 400 microns.
- Full surface coating with 206 Ceramic HTA Fluid, achieving a total dry film thickness of 1mm.
Application Details:
The chimney stack surface was abrasive blasted to ISO 8501-4 SA2.5 (SSPC SP10/NACE 2) standards, achieving a 75-micron angular profile to remove corrosion and ensure optimal coating adhesion. To reinforce corrosion-prone areas, all weld joints were stripe coated with 206 Ceramic HTA Fluid at a 400-micron thickness for added protection. While the stripe coat remained wet, the entire chimney surface was coated using brushes, rollers, and plastic applicators, building up a seamless, highly durable protective layer with a nominal dry film thickness of 1mm.
This robust coating effectively shields the structure from the corrosive impact of SO₂ gas and high temperatures.

Results and Benefits of Resimac Solutions.
The application of Resimac 206 Ceramic HTA Fluid provided superior corrosion protection while reinforcing vulnerable areas, such as weld joints, to enhance the chimney’s structural integrity. Its smooth, non-porous surface minimized contaminant buildup, simplifying future inspections and reducing maintenance costs.
Additionally, the coating improved operational safety by mitigating the risk of structural failure due to ongoing corrosion. By extending the chimney’s service life, this solution minimized unplanned maintenance, ensuring continuous emissions management and compliance with environmental regulations.
