Powder coating: eco-friendly magic from "flour" to "armor"

What exactly is it?

"Freeze-drying" the paint into a fine powder like flour is powder coating. The biggest difference from traditional paint: it does not contain any solvents, and you can paint the wall with water? No, it doesn't add even a drop of water, it's 100% solid powder, truly zero VOCs.

Why is it called "zero waste" paint?

1. The unused powder can be recycled and resprayed, with a utilization rate of up to 99%, and there is almost no waste in the factory.

2. One-time film formation: 70-100 μm thickness can complete the protective decoration, eliminating the repeated process of primer and middle coating.
3. Fast curing: 180-200 °C for 10-15 minutes, the coating immediately turns into a dense "plastic armor", and the hardness and adhesion are instantly full.

Construction is three steps

1. Pretreatment: Degreasing→phosphating→ washing to make the metal surface "hairy" and increase adhesion.

2. Electrostatic spraying: The spray gun makes the powder negatively charged, the workpiece is grounded, and the powder is evenly adsorbed as if it is attracted by a magnet.
3. High-temperature curing: 180-200 °C in the oven, the powder is melted into a liquid, then cross-linked into a solid coating, and cooled.

How to calculate the environmental protection account?

1. VOC emissions: 0 g/L (200-400 g/L for conventional paints)

2. Waste: <1% (30% > conventional spraying)
3. Energy consumption: 15-25% lower energy consumption than water-based paint drying for the same thickness

Common misconceptions

1. "Powder can only be sprayed with metal" ❌

Low-temperature curing powder (130 °C) is now available, which can be sprayed with MDF boards and plastic housings.
2. "Powder color is monotonous" ❌
Through Bonding technology, thousands of effects such as metal flash silver, wrinkles, sand patterns, and imitation wood grain can be achieved.

Summary in one sentence

Powder coating is like putting a "customizable, zero-pollution, lifetime maintenance-free" colored armor on an industrial product, allowing beauty, durability, and environmental protection to shake hands with the same product.
