  • High production capability
  • Versatile equipment options
  • Large- and small-part coatings capability.

What is Electrocoating?

E-coating, also known as electrodeposition coating, is a method of painting that uses electrical current to deposit paint on a surface. The process works according to the principle that “opposites attract.”

The electrocoat process can be divided into four distinct steps:

  • Step one is the pretreatment process, during which metals are cleaned and phosphated to prepare the surface for application of the electrocoat.
  • In step two, the electrocoat bath is applied using ancillary and process control equipment. The electrocoat bath consists of 80% - 90% deionized water and 10% - 20% paint solids.
  • Step three is the post-rinse, where excess paint solids are returned to the tank.
  • Step four is curing in the electrocoated part in the bake oven. The minimum bake schedule is 20 minutes with a part temperature at 375°F for most electrocoat technologies.

What materials can be e-coated?

  • Cold/Hot Rolled Steel
  • Galvanized Steel
  • Iron Castings
  • Zinc Castings
  • Copper/Brass
  • Conductive Composites
  • Aluminum Extrusions and Castings
  • NiZn Plated Steel
  • Stainless Steel
  • Magnesium
  • Chrome Plate


Pretreatment Requirements

Selecting the proper pretreatment is essential to success. PPG Coatings Services can deploy multiple technologies to meet most OEM specifications, including zinc- and iron-phosphating, impellers and air blasters, chrome conversion coatings, and chrome and non-chrome sealers.

What are the benefits of Powder coating?

Electrocoating produces the ideal base for a variety of topcoats, yielding a “dual application advantage,” that results in demonstrably more decorative and durable finishes. As a premier applicator, PPG Coatings Services has the technology and technical expertise needed to pretreat and electrocoat vi0rtually any metal substrate in-house.

Why Outsource Electro Coating?

An e-coat system with the appropriate supporting equipment, such as the treatment system for process fluids represents a significant capital and staffing investment. For low-to-moderate production volumes, outsourcing can be a cost-effective way to obtain the advantages of professional e-coat application for a given part or product.
When production volumes reach the levels that could justify an in-house system, the decision to outsource electrocoating becomes more complex than a "make or buy" evaluation. At that point, it also becomes a “strategic” decision that requires answers to two fundamental questions: “What is our business?” and “Do we want to run a coatings operation?”.
Here are a few of the advantages of outsourcing with PPG Coating Services:

  • Project Analysis: PPG Coatings Services will assist with development and then support the most effective process to meet and exceed the customer's goals.
  • Equipment: PPG Coatings Services can design, build and manage the coating application equipment for maximum efficiency specific to the customer’s product.
  • Coating Application: PPG Coatings Services will provide highly trained personnel for total custom coating system management.
  • Parts Handling: PPG Coatings Services is experienced in packaging, logistics, assembly, inventory control, masking and specialized fixturing.
  • Long-Term Management: PPG Coatings Services' unique "bundle" of skills related to painting technologies allows the customer to focus on the core business without the worries of operating a coating facility.
