Sensitive to heat

When subjected to high temperatures, wood, plastic and other heat sensitive substrates (HSS) can deteriorate, melt, bend or bubble.

Powder coating heat sensitive substrates is as much art as it is science and requires an experienced team to implement correctly. That’s why we’re with you every step of the way, providing a Safe and Easy process to mitigate risks and support your objectives. Our holistic approach respects current factory processes and ensures a smooth integration between software and hardware. And it isn’t just about process; we work in global partnerships with line manufacturers to provide our customers with through-the-line support at every stage of the manufacturing process, pre- and post-production.

How it's done

With Interpon W, the process is faster, safer and greener than traditional coatings. One coat is enough to cover all of an item’s corners, all in one go. And by removing the need to stack the items differently after curing, you can save time and money.

Stage 1: Loading: We start by loading objects that need to be coated on the line.

Stage 2: Pre-heat: In this stage, by pre-heating the substrate we activate moisture which makes the surface suitably conductive to attract the powder when it is coated. While this isn’t necessary for all materials (e.g metal, as metal is highly conductive and allows the powder to stick to the substrate uniformly), it is required for poor conductors such as wood. For the most challenging substrates, including plastics, a conductive primer is required to allow an even coverage.

Stage 3: Spray booth: The object goes into the spray booth and is sprayed with the powder coating.

Stage 4: Melting, flow and cure: The object is placed into the oven to cure, with temperatures varying between 80°C-140°C.


For UV powders, a UV curing section is needed after the main oven.

Stage 5: Cooling: The object is cooled.

Stage 6: Unloading: The cooled object has chemical, scratch, heat and moisture resistance and is Ready to Ship.
