Powder coating is a modern coating technology invented by Dr. S. Erwin Gemmer in the early 1950s. According to the outstanding development of science, powder coating technology is increasingly perfect in terms of quality standards and applications.
Thus, why is powder coating used for high-end aluminium doors and windows? Let’s find out with EBM to better understand this question.
The working principles of powder coating
Powder coating is simply understood as a type of adhesive paint under electrostatic attraction.
The requirement when painting is that the aluminium profile bars must be cleaned from impurities on the surface, creating adhesion during the time of painting.
Need-to-paint materials mentioned here are aluminium bars that are treated to carry (+) ions, electrified paint and gas that carry (-) ions. Under electrostatic attraction, the paint particles adhere to the aluminium bars, creating a strong adhesion.
Advanced and modern coating technology
The paint which is used for this high-grade aluminium doors and windows is a specialized powder coating. With many prominent features, this is the most suitable paint for high-grade aluminium doors and windows.
Powder coating is environmentally friendly and safe for users’ health. Unlike other water-based paints, there are hidden substances that are potentially harmful to users. These substances are contained in the solvents of water-based paints, which can cause adverse effects on the skin or respiratory system.
With the appearance of powder coating, high-grade aluminium doors and windows have high durability when integrating to corrosion resistance and oxidation in outdoor conditions. Aluminium door and window surface will be protected by weather and external forces.
The advantages of powder coating
- When it is powdered coating, the surface of the aluminium door and window frame will have no cracking, peeling, rust, oxidation in outdoor conditions.
- Standard paint thickness is immune to oxidation and corrosion when exposed to heavy rain.
- Powder coating is multi-step tested meeting quality standards; paint colors are even, consistent, and shiny compared to other paints.
- Thanks to using advanced technology, the paint particles firmly adhere to the aluminium bar. Aluminium doors and windows will be not peeled and faded easily.
- Closed coating technology line with synchronous and advanced machinery can save materials, bring high economic efficiency.
- The aluminium door and window surface which is powdered coating is hard to get dirty, so it is easy to clean and maintain.
Extremely high aesthetics, durable paint color and harsh weather resistance are the main reasons that powder coating is popularly used for high-end aluminium doors and windows.
Especially, for European aluminium doors and windows, their powder coating technology meets European standards with extremely good paint quality. This is one of the reasons why European high-end aluminium doors are trusted and widely used for building villas, villas, high-class apartments…
