Powder coating questions, answered

WANAN manufactures thermosetting powder coatings in five documented series — E epoxy anti-corrosion, EZ zinc-rich epoxy primer, and P480, P720 and P1680 weather-resistant polyesters — plus functional and decorative grades: electrical insulation, high temperature, low-temperature cure, MDF, heavy-duty anti-corrosion, bonded metallics, textures and heat-transfer base coats, across epoxy, polyester, hybrid and polyurethane chemistries.

Use a weather-resistant polyester: P480, P720 or P1680 (salt spray 480 / 720 / 1000 h, xenon-arc 500 / 1000 / 1000 h). Choose by exposure — P480 for basic outdoor hardware, P720 for higher humidity or weathering, P1680 for the most demanding projects. Architectural aluminium projects that require the QUALICOAT label use the approved systems on certificates P-1436 (Class 1) and P-1982 (Class 2).

Yes. WANAN supplies RAL K7 shades and matches custom colours from a physical panel, a paint chip or a reference from another colour system such as Pantone, then issues colour panels for approval before production. Specify from a physical reference, because on-screen colours are approximate. A library of about 100,000 formulated sample panels shortens matching for repeat and near-match shades.

Source: Colours & finishes

Smooth gloss, satin and matt; sand texture, wrinkle and hammer; bonded metallics (silver, champagne, bronze and colour metallics); heat-transfer base coats and art effects. Gloss is agreed per project and measured at 60° (ISO 2813). For outdoor use, metallic and textured finishes are built on a weather-resistant polyester such as P480, P720 or P1680.

Yes. For energy-storage cabinets, EV charging stations, battery-pack housings and brackets, candidates are E (1440 h salt spray) or EZ zinc-rich primer (≥ 2000 h) for structural corrosion protection and P480 / P720 / P1680 as weather-resistant topcoats, qualified as a system on trial panels. For steel enclosures of outdoor-use electrical equipment, model WA-DQ 001A is a UL 1332 recognized coating.

Yes. WANAN's CNAS-accredited laboratory runs gloss (ISO 2813), impact (ISO 6272-2), bend (ISO 1519), cross-cut (ISO 2409), pencil hardness (ISO 15184), humidity (ISO 6270-1), neutral salt spray (ISO 9227) and xenon-arc (ISO 16474-2) for project files. Tests outside the accreditation scope are arranged with third-party laboratories such as SGS; to test a specific colour, send the RAL number and the standard you need.

FDA food-contact compliance is not part of WANAN's published certifications. If your part needs it, send the application and the regulation you must meet to the technical team, who will tell you what can and cannot be documented.

Production runs under ISO 9001 and IATF 16949. Every batch is tested in WANAN's own CNAS-accredited laboratory — appearance and colour difference, 60° gloss, particle-size distribution, gel time and cured-film properties — and ships with a certificate of analysis. Customer and third-party audits of the Zhangzhou headquarters are part of the system.

WANAN holds two QUALICOAT approvals: P-1436 for a Class 1 system (gloss category 3, metallic extension) and P-1982 for a Class 2 super-durable system (gloss category 2), both valid until 31 December 2026. The approvals apply to the systems named on the certificates; the P480, P720 and P1680 series are specified by their own ISO test values. Ask for the approved system matching your project's class.

Yes. WANAN issues colour panels — smooth, metallic and textured — for approval before production. For metallics and textures, approval panels are sprayed under production-like settings because film build and gun parameters change the final effect.

Source: Applications

Electrostatic spray at 40–100 kV, 80–120 µm dry film, cured at 190–200 °C object temperature for 10–15 minutes. The same cure window applies to E, EZ, P480, P720 and P1680, so primers and topcoats can run on one line.

Source: Series comparison

80–120 µm dry film, with a working range of 80–180 µm on the flat panel. Thin films reduce hiding and corrosion protection, especially at edges; very thick films can orange-peel, trap gas on castings or galvanised parts and waste powder. Measure edges and recesses separately.

Source: How to measure film thickness

Steel, galvanised steel and aluminium, as well as MDF with dedicated MDF grades. Published test values are generated on phosphated steel panels; on other substrates and pretreatments, performance is confirmed on trial panels. Galvanised and cast substrates may need a degassing preheat or an outgassing-forgiving grade.

Source: Powder coating 101

Iron or zinc phosphate on steel, chrome-free conversion coatings on aluminium, or zirconium / silane systems. Degreasing, rinsing and drying before the booth decide adhesion and corrosion life; weld spatter, oil and fingerprints show through any powder.

Source: Powder coating 101

Orange peel often comes from film that is too thick — stay within 80–120 µm. Pinholes and blisters on galvanised or cast parts usually point to outgassing: add a degassing preheat or ask for an outgassing-forgiving grade. Poor coverage at edges and inside corners is the Faraday-cage effect: adjust gun settings or hanging, and measure edges separately. Under-cure shows as poor solvent resistance and low impact.

Source: How to reduce outgassing

Standard series cure at 190–200 °C object (metal) temperature for 10–15 minutes — the oven set-point must be higher, and heavy parts need longer. For heat-sensitive parts or lines that want cooler ovens, WANAN develops low-temperature-cure grades against the project requirements.
