Pekotek provides modern powder coating lines with a strong focus on environmental sustainability.
What is powder painting?
Powder coating lines can be designed with either chemical and/or mechanical pretreatment, such as centrifugal wheel blasting.
The powder itself is a coating applied as a free-flowing, dry powder. Unlike conventional liquid coatings, which are applied using a volatile solvent, powder coating is typically applied electrostatically and then cured by heat or ultraviolet light. The powder can be either a thermoplastic or a thermosetting polymer.
Powder coating requires either an oven or infrared heating to cure the powder, resulting in a durable surface that is harder than conventional paints.
How environmentally friendly is it?
Powder coating offers several ecological advantages compared to other methods.
The greatest benefit lies in the low environmental impact, as no solvents are used. In powder coating, no liquid solvents are applied, which reduces the emission of harmful substances into the air. This is a significant advantage over traditional wet painting, which uses liquid paints and solvents that may contain hazardous substances such as VOCs (volatile organic compounds).
Further environmental benefits include:
-
Minimal waste: The powder coating is applied electrostatically to the surface, so no excess material is lost — everything can be reused. Additionally, no hazardous waste is generated that requires special disposal.
-
Energy-efficient process: Powder coating usually requires thermal pretreatment of the objects. However, modern technologies allow for low-temperature processes, reducing energy consumption compared to traditional wet painting methods.
-
Durability: Powder coating provides a tough and resilient surface that is more durable than many other coating methods. As a result, coated objects have a longer lifespan and need to be repainted less often, which reduces resource consumption and waste generation in the long term.
In summary, powder coating is a more environmentally friendly surface treatment method compared to other processes.
