ALKA · AUSTRALIAN COATINGS MANUFACTURER
Power Generation
Protect structural and service assets across generation facilities.
SERVICE & APPLICATIONS
Protection matched to the asset.
Generation sites contain external structures, internal plant steel and wet-service assets. ALKA systems support atmospheric protection and maintenance for these surfaces, with separate assessment for process temperature and specialist equipment duties.
External steel
Exposed frames, platforms and supports need protection matched to weather and local corrosion conditions.
Internal service steel
Mild-to-moderate atmospheric areas can use a practical epoxy maintenance build.
Wet utility areas
Pump bases, sumps and selected water-service surfaces need substrate and exposure-specific barrier selection.
ALKYD PRIMERS · ENAMELS · SINGLE-PACK FINISHING
Single-pack finishes for ambient-temperature service assets
Prepared cabinet exteriors, dry equipment supports, workshop parts and ancillary frames at ambient service temperatures may suit single-pack primers and enamels. The finishing requirement should be distinguished from hot plant, cooling-water exposure and other demanding generation duties.
Products to assess for the job
- ALKA 401 · Alkyd zinc phosphate primer
Prepared carbon steel; a corrosion-inhibiting primer for compatible alkyd and enamel finishing routes.
- ALKA 402 · Single-pack acrylic etch primer
A substrate-specific adhesion option for steel and suitable galvanised or aluminium components. This is a thermoplastic acrylic primer, not an alkyd.
- ALKA 410 · Rapid-cure protective enamel
A gloss finishing option for machinery, fabricated components and maintenance work over a compatible prepared and primed surface.
- ALKA 415 · Hammer-tone finish
A decorative textured finish for machine covers, cabinets, enclosures and fabricated metal items where appearance is part of the brief.
Select a complete, compatible primer and finish. The products above are options by role, not a blanket approval to combine every primer and topcoat.
What the applicator or specifier needs
Record actual surface temperature, condensation, cleaning and cooling-water exposure by component. Separate the requirements for identification and finish from operating duty.
Prepare around edges, welds and enclosure details without coating labels, seals or functional interfaces. Check old-paint compatibility before maintenance recoating.
Allow the specified handling and full-cure periods before assembly or service. Include installation damage and subsequent touch-up in the coating schedule.
Write a usable coating schedule
Specify the substrate and preparation, exact primer and finish, individual-coat dry-film thickness, application method, thinning limits, recoat interval and service-cure requirement from current product data. For repainting, document the retained coating and a representative compatibility trial before full application.
Choose the coating for the exposure
Hot surfaces, continuous cooling-water exposure, chemical treatment areas and immersion require purpose-selected systems.
A single-pack route can simplify small batches and routine repainting because it does not require mixing a separate hardener. It still depends on sound preparation, suitable film build and the correct recoat window. Where exposure or the required maintenance interval is more demanding, assess the relevant two-pack epoxy, polyurethane or specialist lining system.
Does fast drying mean the part is ready for service?
No. Touch-dry, recoatable, handleable and fully cured describe different stages. Use the selected product data and actual application conditions to plan each stage. Excessive film build, early overcoating or premature handling can compromise the finish; adding extra thinner or a hardener is not a substitute for the specified application procedure.
SELECT THE COMPLETE BUILD
ALKA systems for this application.
| System | Why select it | Coating build | Total DFT |
|---|---|---|---|
| ALKA-9930 Premium External | Premium corrosion protection combined with a UV-stable, colour-retentive finish Abrasive-blasted carbon steel; external industrial and coastal atmospheric exposure | Alka 404 zinc-rich epoxy primer → Alka 413 high-build epoxy → Alka 421 polyurethane finish | 250–300 µm |
| ALKA-9940 Economical Maintenance | Cost-effective protection for routine maintenance where exposure is not severe Prepared steel in mild to moderate industrial atmospheric conditions | Alka 416 single-pack epoxy coating → Alka 412 or Alka 413 maintenance epoxy | 200–250 µm |
| ALKA-9935 Glass-Flake Barrier Lining | High-build glass-flake barrier delivers strong resistance to permeation, wet service and abrasion Prepared steel or concrete exposed to wet service, abrasion, splash, spillage or aggressive industrial conditions | Substrate-specific primer where required → Alka 414 Glass Flake Epoxy → optional approved build or finish coat | 400–750 µm |
DFT = dry-film thickness. These are nominal system totals; individual-coat thicknesses and application conditions belong in the final coating schedule.
SPECIFICATION & APPLICATION
From surface preparation to return to service.
Build the coating schedule around the substrate and the work that can be achieved on site. For refurbishment, assess the adhesion and compatibility of retained coatings before defining repair boundaries.
- 01Coated-surface temperature
- 02Internal and external zones
- 03Water and chemical exposure
- 04Outage and inspection access
Record surface preparation, environmental conditions, coverage at details and coat thickness. Allow for the specified recoat and cure periods, then inspect and repair defects before release to service.

TECHNICAL QUESTIONS
Details that affect system selection.
How should temperature be described in a coating enquiry?
Provide the temperature at the coated surface, including startup, shutdown and cycling. Ambient air temperature alone does not define the duty of equipment near a heat source.
What belongs in the final technical submission?
Include current TDS and SDS, substrate preparation, the product and thickness schedule, application conditions, inspection criteria and cure requirements. For chemical or immersed service, include written suitability for the actual exposure. Any required certification or durability commitment must be supported by the relevant evidence.
Boilers, exhausts, hot pipework, turbine internals, electrical insulation and nuclear qualification are outside a general protective-paint selection. Record specialist requirements separately.
