Belzona polymeric metal repair composites and protective coatings are specifically formulated for repairing and protecting machinery and equipment in the power industry.
Belzona’s comprehensive range of cold curing, 2-part polymeric coatings and repair composites have been used by the power industry for over 60 years. Our materials are engineered to withstand demanding operating conditions and offer exceptional continual wear resistance plus erosion and corrosion protection.
Whether your plant generates power by nuclear, fossil or renewable means or your facility distributes energy to end users, it is likely you will experience routine or unexpected maintenance challenges that result in increasing operating costs. Belzona provides cost-effective solutions to such maintenance problems by minimizing downtime, labor and equipment replacement costs, whilst increasing the efficiency of the plant and ensuring environmental compliance.
Aggressive erosion and corrosion can seriously impact fluid handling equipment and cooling water systems. Belzona offers cold-applied repair materials like Belzona 1111 to rebuild damaged pumps and protect against chemical attack.
Coatings like Belzona 1321 and 1341 provide long-term erosion and corrosion resistance—1341 even boosts pump efficiency by up to 20%. For water boxes, tube sheets, and end covers, Belzona 5811 delivers reliable corrosion protection. And for cavitation-prone areas like turbine runners, Belzona 2141 helps prevent wear and reduce maintenance costs.
Belzona polymeric coatings and metal repair composites can help to slow down the effects of erosion in solids handling and FGD systems, whilst resisting corrosion even in areas where chemicals and high temperatures are present.
Our high build erosion resistant materials, such as Belzona 1311 (Ceramic R-Metal), Belzona 1811 (Ceramic Carbide) and Belzona 1812 (Ceramic Carbide FP), will restore eroded steelwork, whilst ceramic filled coatings such as Belzona 1321 (Ceramic S-Metal) can extend equipment life.
External corrosion causing thin-wall or through-wall defects can be repaired with Belzona’s cold-applied wraps or bonded plates using materials like Belzona 1111 or Belzona 1212, even on oil- or water-contaminated surfaces.
For pressurized or holed pipes, Belzona SuperWrap II offers a fast, ISO/ASME-compliant in-situ solution—no hot work needed.
Belzona 3412 protects flanges from corrosion and can be peeled back and resealed for easy inspection.
For Corrosion Under Insulation (CUI), use Belzona 3211 (Lagseal) to encapsulate insulation and prevent further damage with a microporous, flexible barrier.
With the ability to be applied by brush or by airless spray, areas such as chemical bunds, channels and sumps can be effectively lined ensuring long-term environmental protection. Belzona’s comprehensive range of polymeric coatings such as Belzona 4311 (Magma CR1) provide chemical resistance against a wide range of aggressive chemicals.
Environmental problems can occur as a result of deterioration of aging equipment resulting in leakage. Belzona 1161 (Super UW-Metal) has the unique attribute to bond strongly to oily and wet metal surfaces. Dependent on their location, even live leaks on pipework and other metallic equipment can be stemmed and sealed in situ using a Belzona leak sealing kit due to its high adhesion and cold curing capabilities.
These cold applied materials eliminate hot work and have been designed to be easy and safe to use. They are resistant to a wide range of chemicals and provide excellent corrosion protection offering long-term solutions.

Cavitation had caused erosion of the parent metal and loss of performance of the turbine. Belzona 1341 and Belzona 1421 had been applied in 1998 but had suffered erosion in this aggressive environment.
Customer had a leak in one of their oil transformer units. They could not replace the flange without emptying the oil in the transformer which would take more time and money.
Customer was looking for a solution to stem and seal oil leakages from flanges and under the high voltage bushing pockets.
