What Is Electrostatic Spray Coating?

Traditional wet painting involves a liquid paint being applied to a surface, often by spraying, and allowing it to dry. Binders in the liquid paint enable it to adhere to the surface being painted. Electrostatic spray coating involves the same spraying technique, but instead of binders, negatively charged surfaces attract positively charged coatings, creating a powerful bond at the molecular level.

Are Electrostatic Spray Coating and Electrostatic Painting the Same Thing?

The terms electrostatic painting and spray coating are often used interchangeably, but they refer to different processes. Both produce a smooth, even coating

Electrostatic Spray (Powder) Coating

• Uses charged, powdered polymer
• Heat cured
• Most durable
• Applied in shop

Electrostatic Painting

• Uses charged, liquid paint
• Air cured
• More durable than traditional painting but less durable than powder coating
• Applied in shop or on site

Applications for Electrostatic Spray Coating

Powder coating is one of the best protections for metal products. Specific coating formulations should be selected for the additional benefits they offer, for example:

• Ultra-smooth Halar is exceptionally durable and has minimal friction
• Durable, corrosion-resistant epoxy is popular for electrical and industrial applications
• UV-tolerant, colorful polyester is commonly used for patio furniture and many household goods
• Exceptional durability and resistance to wear and damage, polyolefin coatings are found on playground equipment and other outdoor applications
• Nylon is environmentally friendly, with applications in medical (including sterilization coating), industrial, and automotive applications, among others
