It is important to coat metals in order to make them durable. The coating reduces the chances of rusting and the day-to-day wear-and-tear of the metals. Most metal fabrication companies use either powder or wet coating for metals.
Metal Coating and the Environment
Metal coating practices have now become more-friendly to the environment than before. Today, the chemicals used in wet coating by either contract manufacturing companies or the manufacturing companies are fast drying – hence less pollution. Emissions from powder coating are not as high and can also be recycled and this makes them very friendly to the environment right here in Oshawa, Ontario.
The Difference between Powder and Wet Coating
Coating generally means painting.
In wet coating, liquid paint is applied on the metal by the use of a pressurized vessel or a spray gun. This coating is recommended for metals that cannot undergo any form of heating or metals that require a specific colour.
Powder coating, on the other hand, refers to the electrostatic application of dry powder on the metal. Unlike wet coating, powder coating does not require a carrier. Once the powder has been applied to the metals, they are baked in an oven at 450 degrees. The heat transforms the powder into a liquid and then a solid form resulting in a thick and solid coating that is much more durable than wet coating.
