DC Current
Direct electrical current.
Decorative Coating
A coating designed primarily for cosmetic and secondary for protection.
Deflector
Conical shaped disc attached to the end of the powder gun to evenly distribute the powder in a 360o pattern. Used to shape and direct the powder pattern.
De-ionised Water
Water containing no ions other than hydrogen, oxygen and hydroxyl ions. Usually produced through the use of ion exchange resins and used for the final rinse in pre-treatment processes.
Delamination
Separation between two layers of coatings or between coatings and substrate.
Delivery
The process of moving the powder through the application equipment to the end product.
De-mineralised Water
Water containing no ions other than hydrogen, oxygen and hydroxyl ions. Usually produced through the use of ion exchange resins and used for the final rinse in pre-treatment processes.
Detergent
An alkali or ionised cleaning or emulsified agent.
Dew Point
Temperature at which water condenses from air at atmospheric pressure. Dew point varies with relative humidity.
Diffuser
A porous material used in an airline to evenly distributes the air.
Dispersion
Suspension of one substance in another.
Dry Blend
Material generally added into the final coating as a dry additive without any melting.
DFT
Dry Film Thickness. Depth of applied coating before curing.
Dry Flow
The properties of a coating powder that relates to the ease of movement or transportation with air or vibration.
Dry Flow Additive
An additive that improves the properties of the coating in the powder state. It improves the free flowing characteristics (for better fluidisation or transporting via feed lines) along with the sieving.
