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.

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.

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.
