Arcdip AN 230 Pigmented Anodic Electrocoat
Arcdip AN 230 is a pigmented anodic electrocoat for interior components and decorative fabrications where corrosion demand is moderate and a simpler, lower cost anodic bath is justified. It builds a self-limiting film at lower deposition voltage than a cathodic system, with corrosion performance below that of a cathodic epoxy of equal thickness.

1. Product description
A pigmented anodic grade for interior components and decorative fabrications where corrosion demand is moderate and the simpler, lower cost anodic bath is justified. It reaches into recesses as any electrocoat does and builds a self-limiting film at lower deposition voltage than a cathodic system, although throw is normally below that of a high throw cathodic epoxy. Because metal dissolves from the part at the anode and is carried into the film, corrosion performance sits below a cathodic epoxy of equal thickness, so this grade is not specified for exterior structural steelwork.
2. Features
- Pigmented anodic grade for interior service
- Self-limiting film at lower deposition voltage than a cathodic system
- Reaches into recesses, with throw below that of a high throw cathodic epoxy
- Simpler, lower cost bath than a cathodic line
3. Recommended uses
Interior enclosures, shelving, furniture frames, fittings and appliance internals in phosphated or zirconium pretreated steel and aluminium. Not specified for exterior structural steelwork.
Substrates. Phosphated or zirconium pretreated cold rolled steel and aluminium, in interior enclosures, shelving, furniture frames, fittings and appliance internals. Zinc-coated steel is taken only where the pretreatment and the bath have been proved on that coating type, because anodic dissolution attacks the zinc layer preferentially.

Typical values, not a specification. Values for each batch are given on its Certificate of Analysis.
5. Application
| Parameter | Guidance |
|---|---|
| Method | Anodic electrodeposition by immersion in a circulating bath, with the part as anode and catholyte cells removing the alkali released at the counter electrode so bath pH holds |
| Surface preparation | Phosphate or zirconium conversion coating, rinsed to demineralised water quality; zinc-coated steel only where pretreatment and bath have been proved on that coating type, because anodic dissolution attacks the zinc layer preferentially |
| Bath make-up and replenishment | Pigmented feeds added to the circulating bath with demineralised water as bath analysis requires |
| Bath temperature and deposition | 22 to 28 °C; 100 to 200 V DC applied over 90 to 150 s, below the rupture voltage of the bath |
| Rinse | Ultrafiltrate rinse followed by a demineralised water rinse, with dragout returned to the tank |
| Cure schedule | 150 to 180 °C metal temperature for 20 min at temperature, confirmed by attached thermocouple oven profile |
| Next step or overcoat | Normally the single coat on interior parts; any topcoat is proved for intercoat adhesion on the combined system to ISO 2409 |
Process. Immersion in a circulating anodic bath at 22 °C to 28 °C, 100 V to 200 V DC applied over 90 s to 150 s, ultrafiltrate and demineralised water rinses, then bake at 150 °C to 180 °C metal temperature for 20 min at temperature.
6. Storage and handling
Store the feed components in closed original containers in a cool, dry place, protected from frost and direct sunlight; the operating bath is kept circulating and is not left standing. Shelf life is stated on the label and Certificate of Analysis. Handle and use the product in line with its Safety Data Sheet.
7. Safety and regulatory information
Read the Safety Data Sheet before use. Safety Data Sheets and regulatory declarations are issued by our technical centre against the product and batch supplied, so they are sent on request rather than published. Request a Safety Data Sheet or declaration.
