Metal Powder Coating for Interiors: An In-Depth Analysis of Aesthetics and Durability
The metallic powder coating for interiors represents the perfect synthesis of cutting-edge design and industrial functionality. This technology offers a superior alternative to traditional liquid paints, providing a stunning finish that captures light and durability that lasts for decades.
Let’s delve into the technical details of this versatile finish and explore the extensive list of objects and surfaces that benefit from its use.
Powder Composition: Resins and Specialised Pigments
For indoor applications, the choice of resin is crucial, as the same UV resistance as outdoors is not required. Indoor coatings are usually based on:
- Epoxy Resins: They offer excellent chemical and corrosion resistance, as well as exceptional adhesion. They are ideal for industrial or functional environments.
- Hybrid Resins (Epoxy-Polyester): These combine the best of both types, offering a highly impact-resistant surface and slight yellowing over time, and are a popular choice for furniture and appliances.
The metallic effect is achieved by incorporating finely ground metallic particles, such as aluminium or bronze. These flakes act as micro-mirrors that reflect light, creating a shine or glow. The way these particles are integrated determines the quality of the finish.
Technical Insight: The Science Behind Metallic Shine
The attractive metallic finish is the result of precise chemical engineering and a controlled application process.
The Application Process: Electrostatic Precision
The success of the metallic finish lies in meticulous control during application:
- Controlled Charging: A low microamperage (around 15 µA) and a specific kilovoltage (60-70 kV) are recommended to prevent metal particles from separating and altering colour uniformity.
- Thermal Curing: Baking at specific temperatures (typically 200°C or 400°F for 10-15 minutes) allows the powder to melt, flow and cross-link, forming a monolithic and extremely durable coating.
