Protection against chemical attacks: securing your industrial equipment
Chemical attacks can cause rapid degradation of metal equipment: corrosion, blistering, cracking, loss of sealing, or production shutdowns. At Xtrem Coatings, we select and apply technical coatings adapted to aggressive environments.
Acids, bases, solvents, immersion, splashes, chemical vapors, or combined abrasion: each situation requires precise analysis. Our goal is to create a durable protective barrier to extend the lifespan of your tanks , pipes, pumps, flanges, agitators, and process components.
What types of chemical attacks?
The choice of coating depends on the fluid, its concentration, the temperature, the mode of exposure and the mechanical constraints.
Acids and corrosive environments
Acids can quickly attack metals and cause corrosion, pitting, or loss of thickness.
Bases and alkaline products
Basic environments require compatible protection to prevent degradation of the substrate and coating.
Solvents and aggressive products
Some solvents can weaken conventional protective coatings. Fluoropolymers are often preferred.
Chemical immersion
Equipment in permanent contact with a fluid requires a continuous, homogeneous and well-dimensioned barrier.
Splashes and fumes
Areas of chemical spray or vapor can be very aggressive, even without continuous immersion.
Chemistry + abrasion
When chemical attack is added to abrasion or turbulence, the system must combine chemical inertness and mechanical robustness.

Parameters to know before choosing a coating
Effective chemical protection is not chosen solely by product name: it is tailored to your actual conditions.
Nature of the fluid
Acid, base, solvent, contaminated water, chemical mixture or effluent: each fluid requires specific compatibility.
Concentration
The same product can be compatible at low concentrations and too aggressive at high concentrations.
Temperature
Temperature often accelerates chemical attack and strongly influences the choice of coating.
Exposure mode
Permanent immersion, projection, condensation, steam or occasional cleaning: the risk is not the same.
Mechanical constraints
Abrasion, shocks, turbulence or handling may necessitate a thicker or more robust system.
Geometry of the room
Angles, welds, flanges, threads or confined areas require appropriate preparation and application.

Our solutions for protection against chemical attacks
We choose the protection according to the corrosion mechanism, the criticality of the part, the exposure and the process constraints.
Halar® / ECTFE
Fluoropolymer solution recognized for corrosion protection in harsh chemical environments.
Tanks, reactors, piping
Good chemical resistance
Thicknesses suitable for harsh environments
PTFE / PFA
Fluoropolymer coatings adapted to the needs of low adhesion, chemical resistance and thermal stability.
Process parts and technical components
Specific chemical applications
Selection based on temperature and fluid
Multilayer systems
When there are multiple constraints, a complete system can combine preparation, primer and functional layer.
Reinforced chemical barrier
Optimized adhesion and continuity
Controls adapted to the specifications
Atmospheric corrosion protection – zinc flake / industrial paint
Chemical corrosion protection – fluoropolymer coating (Halar/PTFE/PFA)
Our methodology
Lasting protection depends as much on preparation and controls as on the product itself. We frame, apply, and monitor.
1. Analysis of the environment
Fluid, concentration, temperature, duration of exposure, immersion, splashes or vapors.
2. Choice of coating
Halar®, PTFE, PFA or other system depending on chemical compatibility and mechanical constraints.
3. Surface preparation
Sandblasting / preparation adapted to the substrate to guarantee adhesion and hold.
4. Application & Controls
Controlled application + thickness control/inspection. Traceability as needed.
In our workshops: resources, processes, rigor and control.
Large rooms?
We handle parts up to 12m (depending on geometry). Send us your plan and photos, and we'll review your case.
