ALKA · AUSTRALIAN COATINGS MANUFACTURER
Agricultural Equipment
Finish and protection for working agricultural steel.
SERVICE & APPLICATIONS
Protection matched to the asset.
Farm machinery and fabricated equipment face weather, cleaning and seasonal storage. ALKA industrial coating systems support external steel finishing and refurbishment, combining suitable primers with epoxy barriers or polyurethane finishes.
Machinery frames
Select the complete build for external weathering, cleaning and the desired colour and gloss.
Refurbishment
Remove soil, oils and residues before preparing sound existing coatings and exposed steel for repair.
Special exposure
Fertiliser, chemical sprays and persistent wetting should be identified separately from normal atmospheric use.
ALKYD PRIMERS · ENAMELS · SINGLE-PACK FINISHING
Enamel, chassis-black and hammer-tone finish options
Fabricated implements, trailer frames, machinery covers and workshop equipment can be assessed for single-pack protective primers and enamels. Choose a gloss industrial finish, satin black or a hammer-tone effect according to the component, then match the primer to the substrate and preparation.
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 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.
- 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 normal weather exposure from fertilisers, crop chemicals, animal waste and aggressive cleaning. Record actual contact, concentration and cleaning practice where relevant.
Remove oil, soil and residues before preparing the metal. Assess galvanised components and existing paint separately; do not assume one primer suits the entire assembly.
Agree colour, finish and assembly timing, including repair of handling damage. Use current product data for the return-to-use period before field exposure.
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
Continuous chemical contact, immersion and direct soil or material abrasion require separate evaluation rather than an ordinary enamel recommendation.
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-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 |
| 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 |
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.
- 01External steel condition
- 02Cleaning and storage regime
- 03Fertiliser or chemical contact
- 04Colour and appearance 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.
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.
What changes when fertiliser or chemicals contact the equipment?
Name the material, concentration and contact period, including cleaning. Chemical-contact areas may need a different coating from ordinary external panels, and severe wear surfaces need their own protection.
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 systems do not establish food-contact approval, universal agricultural-chemical resistance or suitability for soil-cutting and high-wear components.
