Powder coating how-to guides
Step-by-step guides for coaters, fabricators and specifiers: checking cure, measuring film thickness, calculating coverage, choosing a series, qualifying systems and matching colours. Every value comes from WANAN technical data sheets.
How to check powder coating cure with an object-temperature profile
Attach a temperature data logger to a real production part, run it through the oven, and confirm the metal surface holds 190–200 °C for 10–15 minutes. The oven set-point…
6 steps →How to measure powder coating film thickness, including edges
Measure dry film thickness on cured production parts, not only on flat test panels, and record edges and inside corners separately. WANAN series are specified at 80–120…
5 steps →How to calculate powder coating coverage and consumption
Theoretical coverage in m²/kg is 1000 ÷ (specific gravity in g/cm³ × dry film thickness in µm). At 1.5 g/cm³ and 100 µm a powder covers about 6.7 m²/kg before transfer…
5 steps →How to choose a WANAN powder coating series for your part
Start from the part, not the catalogue: substrate, service environment and whether you need a single coat or a primer + topcoat system. E epoxy suits indoor parts and…
6 steps →How to qualify a primer + topcoat powder coating system
Spray the primer and topcoat on trial panels or real parts using your production cure, then test the combined system for inter-coat adhesion, mechanical properties and…
6 steps →How to run a powder coating line trial with WANAN samples
Send your part data, receive candidate series with sample powder and colour panels, spray them on your own line while recording the object-temperature profile, then…
5 steps →How to read a powder coating technical data sheet (TDS)
Read each value together with its test method and conditions: salt spray (ISO 9227), humidity (ISO 6270-1) and xenon-arc (ISO 16474-2) are hours in a laboratory test on…
5 steps →How to reduce outgassing on galvanised and cast parts
Galvanised and cast substrates can release trapped gas during cure, leaving pinholes and blisters. A degassing preheat before coating, an outgassing-forgiving grade and…
6 steps →How to request a powder coating colour match
Send a RAL K7 reference or a physical sample, state the gloss, finish and series, and approve the matched colour panels before production. WANAN’s library of about…
5 steps →How to specify powder coating for a QUALICOAT architectural project
State the QUALICOAT class (Class 1 or Class 2) and gloss category the project needs, ask WANAN for the approved system under certificate P-1436 or P-1982, and have the…
