ALKA · AUSTRALIAN COATINGS MANUFACTURER
Mining Equipment
Corrosion protection for the equipment behind production.
SERVICE & APPLICATIONS
Protection matched to the asset.
Haulage and mobile equipment need coating systems that protect external steel and support practical refurbishment. ALKA primers, maintenance epoxies and polyurethane finishes address chassis, frames, guards and other suitably prepared components.
External frames
A coordinated primer, barrier and finish helps address weather exposure and the appearance of large fabricated components.
Refurbishment
Cleaning and removal of unsound coatings come before repair coating. Assess contamination around oils, grease and hydraulic components.
Finish and identification
Agree colour, gloss and touch-up requirements for visible steelwork and equipment identification.
ALKYD PRIMERS · ENAMELS · SINGLE-PACK FINISHING
Enamels for equipment fabrication and refurbishment
Equipment frames, removable guards, covers, toolboxes and service assemblies can have different finish requirements from the working surfaces of mining plant. Single-pack primers and enamels are useful candidates for appropriately prepared components in atmospheric service, particularly workshop finishing and planned refurbishment.
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 411 · Satin black / chassis enamel
A black finishing option for chassis, frames, transport assemblies and suitable equipment refurbishment.
- 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
Separate appearance surfaces from wear surfaces. Document whether the part sees weather, oil, cleaning chemicals, hot service or repeated impact before choosing a finish.
Pay attention to weld spatter, sharp edges, crevices and bolted assemblies. Confirm how inaccessible faces will be prepared and coated before assembly.
Agree handling and assembly times as well as the repaint interval. A touch-dry film is not automatically ready for clamping, transport or operating loads.
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
Direct ore contact, severe abrasion, continuous wetting and aggressive chemical exposure need a duty-specific system rather than a general enamel finish.
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-9931 General Industrial | Balanced protection, appearance and cost without requiring a zinc-rich primer Prepared steel; moderate internal or external industrial atmospheric exposure | Alka 416 single-pack epoxy coating → Alka 413 high-build epoxy → Alka 421 polyurethane finish | 225–275 µm |
| ALKA-9932 Maintenance / Refurbishment | Reduces preparation demands and supports practical maintenance programs Existing steel where full abrasive blasting is restricted; hand- or power-tool prepared areas | Alka 412 surface-tolerant epoxy × 2 coats → optional Alka 421 polyurethane finish | 200–400 µm plus optional 50–75 µm finish |
| ALKA-9934 Industrial Finish | Efficient two-coat system with attractive finish, cleanability and UV resistance Prepared steel in moderate atmospheric exposure where appearance and cleanability are important | Alka 416 or project-approved Alka epoxy primer → Alka 421 polyurethane finish | 150–200 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.
- 01Component and substrate
- 02Oil and grease contamination
- 03Existing paint condition
- 04OEM requirements and service temperatures
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.
A coordinated coating build
Schematic, not to scale. Follow the selected system for products, layer count and thickness.
TECHNICAL QUESTIONS
Details that affect system selection.
Can protective paint replace a wear liner?
No. Direct impact, cutting and severe mineral abrasion call for an engineered wear solution. Separate these surfaces from the external chassis, guards and frames in the coating scope.
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.
These are protective paint systems for external surfaces. They do not replace engineered wear liners, hardfacing or OEM requirements for load-bearing, moving or high-temperature components.
