Wet Painting

Wet painting has been used for many years as the conventional finishing coat. When manually performed it is a time consuming and the end result may not be even on all surface areas. It is a slow work with a brush and requires more skill (and feeling) from the painter to evenly apply the paint.

With the advent of technological advances, the process has seen various changes. Wet painting makes use of a pump, spray, or another form of pressurized applicant to evenly deliver the paint over the metal surface.

Powder Coating

Powder coating involves the electrostatic application of a dry powder, free-floating coating on a surface which then settles into place with the application of heat. This powder coating can come in a number of varieties depending on whether it’s made of polyurethane, polyester, acrylics, straight epoxy, or polyester-epoxy.

The end result of powder coating finishing is a tough, thick finish, which is harder and more durable than common paints. Powder coating is popularly used on a number of products, including automobile parts and various household appliances, especially outdoor items like fences, railings, and doors that are constantly exposed to heat and the weather.

Why is Powder Coating Better than Wet Painting?

The battle between the two types of painting is essentially the battle between the wet and dry method of painting. Traditional solvent-borne paints require mixing with other liquids in the correct proportionso the end result may not be identical. It is also more prone to heat and weather than powder coating.

Powder coating particle contains resins, modifiers, pigments, extenders and in case if it’s a reactive system it also consists of the curing agent.Even a single coat provides high film thickness and stronger effect which is the main reason it is highly used in architectural and metal finishing industries. It provides a superior finish that eliminates many issues associated with wet paint.

Why should you choose powder coating rather than wet painting?

  • More environmentally-friendly – It contains near zero volatile organic compounds and about 99% of over spray powder can be recovered and reused.
  • Due to the thermal bonding process coated surface stays secure from scratching, fading, chipping and wearing and colors stay vibrant and bright for a longer period of time. It also provides a more uniform coating.
  • Can be heated easily at high temperature.
  • Does not require any solvent to keep the binder and filler parts in liquid form.
  • A large variety of texture, color and design can be used.
  • Extremely durable and resistant to ultraviolet rays.
  • Costs – Using powder reduces labor costs, lower energy costs, and less waste, which means savings for the consumer.
  • Safety – While wet paint contains carcinogenic, is flammable and full of VOC’s (Volatile Organic Compounds), powder contains no solvents and is generally VOC-free. None of the health issues or fire threats from paint is associated with powder.
  • Environment – Powder meets the air and water pollution control standards of the EPA (Environmental Protection Agency). It is a clean, economic process because any overspray can either be reused or returned to a hopper for recirculation. Another operational savingsfor the consumer.
  • Includes many customized finishing colors and textures, because the powders can be expertly manipulated and can withstand bending without flaking or cracking.
  • Fast result – The main advantage of powder over paint is that it is cured in just 20 minutes, which means the piece is ready to put to work almost immediately.

The application of powder coating is done using an electrostatic spray. It applies the same principle in which a magnet attracts steel. The part to be coated is grounded and the powder is charged so that it can stick to it, resulting in at hick and strong coating. Your metal furnishings will still look good even after years of usage.
