What is Aluminium Powder Coating?
"Transforming aluminium surfaces with advanced electrostatic coating technology for superior durability and aesthetics"
Aluminium powder coating is an advanced surface finishing technique that applies dry paint to aluminium products through electrostatic charging. This innovative process involves electrostatically charging powder particles and spraying them onto the aluminium surface, where they adhere uniformly before being cured in high-temperature ovens. The result is a durable, attractive, and highly protective coating that significantly outperforms traditional liquid paint systems.
