Key features
Technical data
Coating properties measured on cured films under the conditions stated in the WANAN E series technical data sheet. Every value is tied to its test method.
| Property | Result | Test method |
|---|---|---|
| Gloss, 60° | As agreed | ISO 2813 |
| Impact | 50 kg·cm | ISO 6272-2 |
| Flexibility (mandrel bend) | ≤ 3 mm | ISO 1519 |
| Cross-cut adhesion | Class 0 | ISO 2409 |
| Pencil hardness | H | ISO 15184 |
| Neutral salt spray | 1440 h | ISO 9227 |
| Resin chemistry | Epoxy resin with matched hardener |
| Specific gravity | 1.2–1.7 g/cm³ (depends on colour) |
| Appearance | Free-flowing powder |
| Colours | Full colour range available |
| VOC | Essentially no VOC emission during application; RoHS-tested (SGS) |
Application parameters
| Application method | Electrostatic spray, 40–100 kV |
| Cure schedule | 190–200 °C (374–392 °F) for 10–15 minObject (metal) surface temperature, not oven set-point |
| Film thickness | 80–120 µm recommended; 80–180 µm working range |
| Appearance | Free-flowing powder |
| Packaging | 25 kg carton, non-hazardous for transport |
| Storage | Cool, dry, below 35 °C (low-temperature-cure grades below 25 °C) |
| Shelf life | 6 months |
Cure temperature is the object surface temperature. Oven set-points must be adjusted to the part mass, line speed and oven type so that the metal itself reaches 190–200 °C for 10–15 minutes. Pretreatment must meet the agreed specification; film thickness and application method influence colour, gloss and appearance, and laboratory panels differ from production parts, so gun settings are finalised on the customer's line.
Where E series is used
Epoxy chemistry gives dense, chemically resistant films with strong adhesion to prepared steel, which is why E series is used as the anti-corrosion coating on industrial equipment, switchgear, transformer housings, racking, pipe clamps, fitness equipment and general metal structures. Epoxy films chalk under UV, so E series is specified for indoor, sheltered or non-UV-critical parts; for outdoor colour and gloss retention, see the P series polyesters or an E/EZ primer under a P topcoat.
Typical applications
- Industrial equipment & machinery
- Home appliances (indoor parts)
- Energy storage & electrical enclosures
- Furniture & metal products
- Automotive & transport components
Compliance & quality system
WANAN powder coatings are produced under quality, environmental and occupational-health management systems certified to ISO 9001:2015, ISO 14001:2015 and ISO 45001:2018, and the design and manufacturing of thermosetting powder coatings is certified to IATF 16949:2016. Batch testing is carried out in WANAN's in-house laboratory, accredited by CNAS (L15415) to ISO/IEC 17025:2017.
SGS reports (2026) on WANAN powder coating samples show compliance with RoHS Directive (EU) 2015/863, REACH SVHC candidate list screening at ≤ 0.1 % (w/w), soluble heavy metals, and California Proposition 65 limits for lead, cadmium and phthalates. Results apply to the tested samples; see certifications & compliance for report numbers and scopes.
Colours & finishes
Full colour range available. RAL K7 shades, custom colour matching from a sample panel, and gloss levels agreed per project (measured at 60°, ISO 2813). WANAN maintains a library of roughly 100,000 formulated sample panels, which shortens matching time for repeat and near-match colours. See colours & finishes.
Packaging, storage & supply
- 25 kg cartons; non-hazardous for road, sea and air transport.
- Store in a cool, dry place below 35 °C; 6-month shelf life from date of manufacture.
- Produced across 7 production bases in China and Southeast Asia with a group capacity of about 80,000 t/year.
- Minimum order quantity, lead time and Incoterms are confirmed per project on request.
Frequently asked questions
Is E series suitable for outdoor use?
E series is an epoxy coating and is specified for indoor or non-UV-exposed parts. Epoxy films lose gloss and chalk under sunlight. For outdoor colour and gloss retention WANAN recommends the P480, P720 or P1680 weather-resistant polyesters, or an E series primer under a P series topcoat after inter-coat compatibility has been verified on trial panels.
What is the difference between E and EZ?
Both are epoxy anti-corrosion powders cured at 190–200 °C object temperature. E series is a single-coat protective finish tested to 1440 h neutral salt spray (ISO 9227). EZ series adds high-purity zinc as the functional filler, provides cathodic protection and is tested to at least 2000 h; it is used as a primer under a topcoat on heavy-duty steel structures.
Can E series be used for FBE pipeline coating?
No. E series is a general industrial anti-corrosion epoxy powder. Fusion-bonded epoxy (FBE) and 3PE pipeline systems require dedicated grades with specific gel time, cathodic disbondment, impact and hot-water resistance data, plus qualification to the project standard. WANAN supports pipeline projects through a separate specification and qualification process; contact us with the standard and line conditions.
