Curing and Oven Processes
Curing transforms applied powder into a durable, protective finish. In this section, you’ll learn about temperature control, oven types, and best practices for achieving optimal results.

What is curing in powder coating?
Curing is the process where powder coating melts, flows, and chemically bonds to the metal surface.
This transforms the powder into a durable, continuous protective and decorative layer.
How hot should a powder coating oven be?
Powder coating ovens typically operate between 160°C and 200°C, depending on the powder type.
Proper oven temperature ensures full curing without degrading the coating.
How long does powder coating need to cure?
Curing usually takes 10–30 minutes at the recommended temperature.
Time varies with part thickness, powder type, and oven efficiency.
Can powder coating be under-cured or over-cured?
Yes, under-curing leads to weak adhesion and poor durability, while over-curing can cause discoloration or brittle coatings.
Accurate temperature control and timing are essential for quality results.
What is the ideal temperature for aluminium vs steel?
Aluminium typically requires slightly lower curing temperatures due to its thermal conductivity.
Steel can withstand higher temperatures, which helps achieve uniform flow and adhesion.
How do you prevent powder coating defects in the oven?
Ensure consistent temperature, clean oven interiors, avoid overcrowding, and use proper racking.
This prevents uneven curing, runs, or texture defects.
What are the signs of poor curing?
Signs include powder flaking, sticky surfaces, dull finish, or reduced corrosion resistance.
Testing adhesion and surface hardness can confirm proper curing.
Can outdoor conditions affect the curing process?
No, curing occurs inside the oven under controlled conditions.
However, post-cure exposure to moisture or dust should be minimised until the part cools.
How do conveyor ovens work for powder coating?
Conveyor ovens move parts through a controlled heat zone for continuous, consistent curing.
They are ideal for high-volume production with repeatable quality.
Is post-curing ever necessary for powder coatings?
Post-curing is rarely required but can enhance chemical resistance or durability for specialty powders.
It involves additional heat treatment after the main curing cycle.
