ALKA · AUSTRALIAN COATINGS MANUFACTURER
Tank Farms & Terminals
A coating schedule for tanks, transfer areas and supporting steel.
SERVICE & APPLICATIONS
Protection matched to the asset.
Terminal coating decisions extend from exposed tank shells to internal linings and containment. ALKA systems help separate these duties while supporting practical maintenance planning around storage operations and access.
Tank exteriors
Shells, roofs, stairs and pipe supports need atmospheric corrosion protection and a suitable finish.
Storage and transfer
Internal tank linings and loading-area containment follow the specific stored product and contact conditions.
Maintenance planning
Survey coating condition and define preparation, repair boundaries and the full cure window before returning assets to service.
ALKYD PRIMERS · ENAMELS · SINGLE-PACK FINISHING
Coordinate exterior colours and practical maintenance
Selected access items, equipment housings, workshop-finished parts and suitable tank exteriors in mild atmospheric service can be considered for single-pack primer/enamel finishes. Fuel-transfer, spill and containment surfaces need distinct specifications even when they share the same asset colour.
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 403 · Red oxide anti-corrosive primer
A primer option for prepared ferrous metal, fabricated steel and general maintenance; confirm the selected finish compatibility.
- ALKA 410 · Rapid-cure protective enamel
A gloss finishing option for machinery, fabricated components and maintenance work over a compatible prepared and primed surface.
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
Separate atmospheric exteriors, bunds, transfer points, tank bases and internal linings in the asset schedule. Record the fluids and temperatures involved.
Assess contamination and existing paint before planning local repair. Pay particular attention to seams, bolted details and areas that retain water.
Agree identification colours, access for future inspection and the coating repair procedure. Keep lining cure and release requirements separate from exterior finishing.
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
Fuel contact, tank interiors, chemical bunds and persistent wetting need an approved system for that service.
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-9937 Severe Maintenance | Combines surface tolerance, high build and glass-flake barrier performance for demanding maintenance work Prepared steel, galvanised steel, aluminium or stainless steel in difficult maintenance environments, subject to technical approval | Alka 418 MIO glass-flake surface-tolerant epoxy; one or two coats as specified | Nominal 250–600 µm depending on coat schedule |
| ALKA-9936 Chemical-Resistant Lining | Higher chemical resistance than standard epoxy systems for demanding process environments Prepared steel or concrete in tanks, bunds, process areas and secondary containment | Alka Tanklin 100 and/or Alka Tanklin Chem system selected to suit the chemical service | 450–600 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.
- 01Stored product and service changes
- 02Liquid and vapour exposure
- 03Existing lining condition
- 04Outage and filling requirements
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.
Can the same lining be used when a tank changes service?
A change in contents, temperature or cleaning can change compatibility. Review the existing lining condition and new exposure before approving continued use or specifying a replacement.
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.
Tank integrity, hazardous-area controls and terminal operating procedures remain part of the wider asset design. Lining compatibility and any fuel-quality requirements must be addressed for the actual stored material.
