What Is Electropainting?
On site refinishing is exactly what it sounds like. Steeltech
Electropainting, Inc.® shall send a team of
experienced craftsman to electrostatically apply two component chemical coating primers
and finishes tailored to meet the needs of each individual substrates refinishing needs.
Leaving a finish, which is either equal to or in most cases far superior to a factory
looking or performing finish.
On a scheduled day a team of Steeltech®
skilled craftsmen arrive with their mobile unit at the client's workplace. The
items to be refinished are first washed to remove dirt and grease, and then wet sanded to
provide a tooth between the surface substrate and the new finish system. Masking is
applied where necessary. The electrostatic coating process applies a mild negative
electrical ground charge to the item to be refinished.
A special electrostatic spray gun charges the refinishing material with a positive
electrical charge. The material is attracted like a magnet to the item. This assures
uniform coating application with no overspray, or fog.
Cleanliness is maintained at all times. A light tack coat is applied first, followed by
a full wet coat, which dries within 30 minutes. Coatings are available in an array of
decorator colors, including blends and matches to existing office décor. All materials
are nontoxic and all equipment is UL and FM approved.
THE HISTORY OF ELECTROSTATIC
Electrostatic is a term used for a special type of coating application equipment, which
was developed back on March 6th, 1938, by a young man whose last name was Ransburg. He
developed a system (primitive by today's equipment) where an efficiently applied electric
charge could be sent into liquid paint and then in turn ground the object they intended to
coat, the particles of paint should be attracted to the surface of the object and there
should be little waste. The demonstration of this technique was done using a metal salt
The shaker was hung in front of a small spray gun, and when the spray was turned on for
a few seconds only one side was coated. Then four fine wires, spaced evenly around the
shaker were charged with electrical current and the shaker was grounded. When the spray
was repeated, it was coated on all sides, top, and bottom.
This is the same example that can be used today. A conventional spray paint application
only goes to the surface directly in front of the spray gun. An electrostatic coating
application wraps the material around the substrate ensuring an even mill thickness of the
coating system. This leaves behind a finished coating without the unevenness, high and low
spots of conventional paint spray applications. Brush painting of these types of
substrates can not even be considered here due to their historically poor non scientific
applications as well as being a non atomized applied finish.
Atomization is the breaking down of a liquid by air pressure into a small particle mass
therefore creating a spray. This is how conventional paint spray equipment basically
works. Air pressure is used to breakdown the paint and by doing so creates a radical
forward velocity to blow paint onto the surface directly in front of the spray gun. As
well as create a tremendous amount of damaging unsightly overspray.
Modern Ransburg #2 process electrostatic equipment breakdown the coatings by an
electrostatic charge and not by air pressure or any type of mechanical atomization.
The advantage this has over conventional spray painting is that there is minimal
forward velocity, which keeps the particles of coating under the control of the electrical
field. This positively charged coatings are in turn drawn onto the grounded substrate,
wrapping the material around the object just as the salt shaker was coated due to positive
vs. negative attraction. And of course no overspray.
The Steeltech Electropainting, Inc.®
electrostatic application system is the only way to refinish existing on site
architectural aluminum and decorative metal back to a once again new product finish. All
work is backed by written warranties against cracking, peeling, and delaminating, from
exposure to Florida's normal harsh environmental conditions.
