What is Powder Coating? A Complete Guide

Powder coating is a dry finishing process where electrostatically charged polymer powder is applied to a grounded metal surface and cured under heat (180?200?C), delivering a uniform, durable film that outperforms liquid paint in every key metric.

How It Works

1. Surface Preparation: Degreasing, shot blasting or zinc phosphating.
2. Application: Electrostatically charged powder clings uniformly to all surfaces.
3. Curing: Heat melts and crosslinks the powder into a durable film.

Key Advantages Over Liquid Paint

• Zero VOCs ? no solvents, no harmful emissions
• Superior impact resistance and flexibility
• No runs or sags on complex geometries
• Overspray recovery ? virtually zero waste
• Wide finish range: gloss, matt, texture, metallic
