Beginning with the Right Coating Process

Coating refers to the process of applying a paint finish to a particular substrate such as metal, wood, or plastic. The coating of a product is done for various purposes such as protection, durability, and decoration. HERR provides systems for three different coating processes;  powder, electrocoat, and liquid spray/dip.

A Coatings Comparison Table is also available by clicking here. This table compares powder, electrocoat, and liquid coatings with respect to substrates, performance, operating cost, capital cost, environment, and operational issues.

Powder Coating
Powder coating is a dry finishing process that results in an attractive, durable, high-quality finish. The powder coating process is also environmentally friendly because no solvents are used resulting in only negligible amounts of V.O.C’s released into the air. Another advantage is minimal waste because unused or oversprayed powder can be recovered and disposed of easily and safely.

For additional information on powder coating, please
visit the Powder Coating Institute (PCI) website at

Electrocoating
The electrocoating (e-coat) process is an organic coating method that uses electrical current to deposit paint onto a part or assembled product. E-coat makes the product last longer because of its unique ability to resist chipping, scratching, rusting, and UV. The e-coat process can keep costs down because many parts or products can be coated at once and run through an e-coat tank at high speed. A popular advantage for e-coat is its environmentally friendly process which produces ultra-low V.O.C’s and is OSHA and EPA compliant.

Liquid Spray/Dip
Liquid coatings are available in a variety of chemistries and are generally recognized as epoxies, alkyds, polyesters, acrylics, urethanes, and waterbase. Liquid coatings are typically applied by spray, dip, or flow applications. The optimal application method depends on the part to be painted, its configuration, and performance requirements.
