Keeping your powder dry

MANUFACTURING - The story of keeping your powder dry and making sure its thermally insulated

The problem 

Powder coating was first commercially used in the 1970s, but has only recently become the fastest growth area in the painting industry. It is a type of coating that is applied as a free-flowing, dry powder, which is ‘cured’ in a specialist oven at high temperature for a short period (usually around 200 °C for 10 minutes). Powder coatings are increasingly popular as nearly all wet paint systems require more than one coat and take a long time to dry. But powder coating can be applied, cured and ready to pack in under an hour. 

While it is relatively easy to apply a thin powder coating it is very difficult to apply a thick coating. As the film thickness is increased, the film becomes more and more orange peeled and textured eventually starting to sag and run.It is important to find a way of increasing the film thickness to allow the development of a powder coating with improved thermal insulation for handrails. This is to comply with new Building Regulations. 

The solution 

This highly innovative company are serial problem solvers in their sector. They have solved all the considerable production problems to produce a commercial powder coat that includes a glass or ceramic micro sphere, which significantly improves its insulation properties. It can now be used on handrails and comply to the new rules.
