Powder coating is a versatile surface treatment used to protect metals and other materials from corrosion, dents, and scratches. Let’s dive into the details:

Powder coating involves applying a free-flowing powder electrostatically to a surface.

The powder can be either a thermoplastic or a thermoset polymer.

Unlike traditional liquid paint, which uses an evaporating solvent, powder coating doesn’t require solvents.

It provides excellent rust prevention, color uniformity, and scratch protection.

Metals tend to corrode under normal conditions, even stainless steel.

Powder coating offers a protective surface layer that is corrosion-resistant and tough.

It’s commonly used on steel, aluminum, and plastic.

Advantages include:

• Rust Prevention: Protects against corrosion.

• Tougher Than Paint: Provides a durable finish.

• High-Quality Surface Finish: Uniform color and texture.

• Wide Aesthetic Range: Available in various colors and finishes.

• No Volatile Compounds: Environmentally friendly.

• Fast Curing Time: Efficient process.

Powder coating is divided into three categories:

• Thermoset: Generally less expensive and easy to apply.

• Thermoplastic: Offers higher performance.

• UV Curable: Cures under UV light.

The process involves:

• Preparation: Cleaning the surface to remove impurities.

• Application: Electrostatically applying the powder.

• Curing: Heating to harden the powder into a protective coating.

Jazan employs various methods based on size, material, and cleanliness.

For ferrous or iron-based items, they use a phosphate coating followed by quick drying in the oven.

Aluminum parts undergo an etching, degreasing, and chromate conversion process.
