Surface Coating

Definition
Surface coating is the application of a coating to a substrate utilizing some form of application method.

Pollutants of Concern

 * PM - from spray atomization
 * PM10 - from spray atomization
 * PM2.5 - from spray atomization
 * VOC - from evaporative losses during dry time and curing
 * HAPs - from evaporative losses during dry time and curing

Application Methods
The application method used to apply a surface coating will determine the coatings transfer efficiency and compliance with coating rules intended to limit overspray and particulate emissions from the surface coating operation. The most common application methods include the following:

Spray application methods

 * Airless
 * Air-assisted airless
 * High-volume, low-pressure spray (HVLP)
 * Aerosol
 * Powder coating
 * Thermal spray

Non-spray application methods

 * Roll coating
 * Flow coating
 * Brush coating
 * Dip coating
 * Manual application
