When people talk about durable and flawless finishes in modern manufacturing, they’re almost always referring to electrostatic powder coating. And for decades, Statfield has been the name industries trust when they want precision, speed, and uniform coating quality.
1. What Exactly Is Electrostatic Powder Coating?
Electrostatic powder coating is a dry finishing process where fine powder particles are electrostatically charged and sprayed onto a grounded metal surface.
The moment charged particles reach the surface, they cling tightly due to its attraction. Then the coated part goes through heating, where the powder melts, flows and cures into a seamless protective layer.
This process is also known as:
- Electrostatic coating
- Electrostatic powder spraying (EPS)
The result? A durable, uniform, corrosion-resistant finish with excellent aesthetics.
2. How It Works (Step-by-Step)
Step 1: Surface Preparation
Good coating starts with a clean base.
Oil, rust, dirt, and oxidation are removed through chemical pretreatment or shot blasting. Proper prep ensures the powder bonds evenly and lasts longer.
Step 2: Charging methods
There are two primary charging methods:
a) Corona Charging
A high-voltage field charges powder particles negatively inside the spray gun. They instantly move toward the grounded component.
Best for high-speed production and large surface areas.
b) Tribo Charging
Powder is charged through friction while passing through a PTFE tube.
Ideal for recessed, complex shapes where deeper penetration is needed.
Step 3: Powder Spray Application
Step 4: Curing and Baking
Once coated, the part goes into a curing oven.
At high temperature, powder melts, cross-links, and forms a strong, continuous coating film.
This coating is now resistant to:
- Impact
- Moisture
- Chemicals
- UV exposure
- Abrasion and corrosion
3. Why Statfield Powder Coating Machines Lead the Industry
Key reasons industries choose Statfield:
- Uniform coating thickness with outstanding film quality
- High transfer efficiency → less powder consumption
- Fast color change booths for high-mix production
- Optimized air flow and extraction inside the powder coating booth
- Safe, controlled static sharged environment
- Long-life equipment designed for 24/7 industrial operations
From automotive to appliances, from fabrication units to heavy engineering Statfield’s deliver consistent, repeatable results.
4. Types of Electrostatic Coatings Uses
Different coatings serve different purposes. Industries commonly choose between:
Epoxy powders → Strong chemical resistance
Polyester powders → UV resistance for outdoor use
Epoxy-polyester hybrids → Balanced protection
Metallic and textured powders → Aesthetic finishes
Particle size and resin blend also influence:
- Melt flow
- Adhesion
- Final coating thickness
This is why selecting the right powder is as important as the right machine.
