Powder coating is covering a steel or aluminium surface with a layer of powder. The biggest difference between painting and a powder coating is that the powder coating in applied as a dry powder, without the need for a solvent. After the powder has been applied, it is melted in a hot oven to create a homogeneous skin.
The advantage of powder coating is that the result is harder than traditional paint: tougher, more scratch resistant and wear resistant. This makes powder coating a cost-efficient and high-quality finish for metal product series.
