Chemcote Power Generation Coating Solutions
Advanced Anti-Corrosion, Extreme Temperature and Asset Integrity Coatings for Power Generation & Transmission Infrastructure
Protecting power generation and energy transmission infrastructure requires specialised engineering coating systems capable of withstanding aggressive chemical exposure, high thermal cycling, continuous salt water immersion and severe mechanical wear. Critical power utility assets including heat exchangers, demineralisation vessels, cooling water (CW) conduits, hydro penstocks, transformers and high-voltage transmission structures face rapid pitting corrosion, galvanic degradation and micro-fouling. Without advanced surface protection, these harsh operating conditions lead to forced outages, unexpected capital equipment failure and escalating maintenance costs.
Chemcote provides industry-leading, Australian-owned protective coating applications, NACE and ACA certified inspections, design specifications and asset refurbishment services across Australia. Servicing major utility providers including Energy Australia and co-generation facilities, Chemcote deploys high-performance vinyl ester glassflakes, copper-flake anti-foul systems and surface-tolerant epoxies to extend power asset service life while maximising fluid dynamics and operational uptime.
The Power Generation Corrosion Challenge
Operating thermal, hydro and co-generation power infrastructure presents severe chemical and structural degradation hurdles:
Persistent Salt Water Leaks & Aggressive Immersion: Pipe services and structural steelwork in turbine halls frequently endure continuous salt water leaks from faulty valves, reclassifying atmospheric areas into harsh immersed environments.
Marine Fouling in Heat Exchangers & CW Systems: Intake screens, seawater conduits, butterfly valves and condenser water boxes suffer from rapid marine growth and micro-fouling, severely choking cooling fluid throughput.
Chemical Attack in De-Salination & Water Treatment: Anion, cation, polisher and ferric sulphate storage vessels experience severe chemical attack across extreme pH ranges (0 to 13).
High Maintenance Costs & Access Restrictions: Traditional dry abrasive blasting in turbine halls or high-voltage switchyards creates prohibitive containment costs and severe dust hazards.
Why Chemcote? The Technology Advantage
Chemcote shifts the maintenance paradigm by deploying surface, wet and environment-tolerant glassflake coatings combined with high-pressure water blasting (up to 20,000 psi). Our specialised technologies eliminate the need for costly abrasive blasting containment, allowing full restoration of critical power assets on site or within our workshop.

Key Technical Benefits
1. Long-Life Seawater & Marine Fouling Barriers
Our Chem-tect 300 series glassflake vinyl esters top-coated with long-life copper-flake filled polyester resin prevent marine growth, outlasting original OEM heat exchanger and condenser water boxes.
2. Confined Space & Water Treatment Vessel Protection
Solvent-free, low-odour Epo-Chem RS 500P (MIO Zinc) and RA 500 series provide impermeable chemical barrier linings for polisher, anion, cation and demineralisation vessels with rapid cure times.
3. Immersed-Grade Armour for Structural Steelwork
Using high-pressure water blasting up to 20,000 psi and surface-tolerant epoxies, Chemcote transforms corrosion-prone pipe supports into heavy-duty, immersed-rated assets, saving hundreds of thousands of dollars in replacement costs.
4. Extreme Temperature & High Voltage Resistance
Our specialised high-temperature coatings (Hot-cote 900 series) and dielectric barriers withstand operating temperatures up to 850°C and protect transformers, high-voltage transmission towers and terminal structures.
Specialised Power Generation Solutions
1. Heat Exchanger, Condenser Water Box and Strainer Overhauls
Complete rebuilding of badly corroded condenser water boxes, tube sheets and self-cleaning seawater strainers using Chem-tect 300 series. Applying copper-flake anti-foul technology guarantees long-term flow efficiency.
2. Demineralisation, Polisher and Water Treatment Vessels
Internal re-lining of anion, cation, filter, polisher and ferric sulphate storage tanks. Applied on site or in our workshop, our vinyl ester glassflakes withstand aggressive water treatment chemicals.
3. Critical Support Structures, Pipe Bridges and Turbine Halls
Surface preparation using small-footprint high-pressure water blasters (20,000 psi) and application of Epo-Chem RS 500P and RA 500 topcoats to safeguard critical overhead pipe services against active salt water leaks.
4. Hydro Penstocks, Cooling Towers and Substation Assets
Heavy-duty internal linings for hydro penstocks, CW conduits and concrete cooling tower structures, combined with specialized external coatings for transformers, terminal structures and high-voltage transmission towers.

Frequently Asked Questions
How does Chemcote protect cooling water heat exchangers from marine fouling?
We apply Chem-tect 300 series glassflake vinyl ester to rebuild damaged water box metal, top-coating the surface with a specialized copper-flake filled polyester anti-foul resin. This non-toxic barrier prevents bio-fouling and marine growth, maintaining maximum fluid flow and cooling efficiency.
Can Chemcote coat structural steel in turbine halls without using dry grit blasting?
Yes. We utilise small-footprint high-pressure water jetting machines operating up to 20,000 psi combined with surface-tolerant epoxies like Epo-Chem RS 500P. This eliminates abrasive blasting dust and containment costs, allowing work to be completed safely inside active turbine halls.
How do Chemcote internal linings withstand water treatment chemicals in polisher vessels?
Our Epo-Chem RA 500 and Chem-tect 300 series vinyl ester glassflake linings are formulated for continuous immersion across an extreme pH range of 0 to 13. They form an impermeable chemical barrier inside anion, cation and demineralisation vessels, preventing chemical attack and structural steel loss.
What options does Chemcote provide for high-temperature power station components?
For power plant components operating at elevated thermal conditions, we deploy our Hot-cote 900 and RF 300 series coatings. These systems offer continuous high-temperature resistance up to 180°C in immersed conditions and up to 850°C for dry external surfaces such as exhaust stacks and steam lines.
