☑️ Definition of furnace color
Furnace paint is produced in the industry in the form of powder coatings or sometimes in liquid form
Electrostatic coating is the official name of a wide range of these products.
This type of metal heat-resistant coating, at first glance, is no different from the usual combination of paint or varnish.
Differences are felt during work.
If the structure of simple colors collapses at high temperatures,
Therefore, the heat-resistant coating on the metal preserves the structure and physical properties of the metal.
Also, heat-resistant paints perform their direct protective function as anti-corrosion.
By protecting the metal from high temperatures, they also protect it from aggressive agents such as corrosion.
By choosing the right color combination for metal and taking into account all the design components, you can
Achieve maximum effect in protection and ergonomic properties.
☑️ Electrostatic powder coating
Powder coating is the process of using a fine, dry, free-flowing powder material on a metal layer and baking it to
It can create a durable and decorative coating in the form of an oven paint.
The powder coating may be a polymer or a thermoset that
They create heat removal from chemicals and react to the powder when heated. Thermoplastics are melted and placed on it after heating and
No additional chemicals are involved in this process.
The method of using both polymers is almost the same and the final appearance is the same.
During the use phase, the powder coating changes shape and
An electrostatic process causes the powder to adhere to the surface.
At that time, the powder granules and the surface are jointly charged with electrostatic energy.
The powder coating should be heated in an oven for 10 minutes at a high temperature of approximately 400°F (200°C).
This temperature melts the powder paint and allows it to be absorbed.
☑️ Types of electrostatic powder coating
Powder coating is one of the most popular furnace colors as part finishing tools.
This coating creates countless different colors from glossy to matte
It has many advantages over ordinary paint.
Powder coated items have many applications from home to industry.
We divide powder coatings based on types of polymer resins, pigments and other additives that are added in powder form.
There are variations in powder coating depending on whether it is made of acrylic, polyurethane, polyester, polyester-epoxy or straight epoxy.
Electrostatic powder coating is also cheaper, more durable and environmentally friendly
It is one of the best ways to complete any metal piece.
☑️ The benefits of electrostatic powder coating over other coating processes
Powder coatings are solvent-free and release a small amount of volatile organic compounds (VOC) into the atmosphere;
Therefore, there is no need to buy expensive pollution control equipment.
Powder coatings can produce much thicker coatings than conventional liquid coatings without damage or sag.
A wide range of special effects are easily achieved using powder coatings that are impossible to achieve with other coating processes.
Cure times are significantly faster with powder coatings compared to liquid coatings, especially when using purple powder coatings or low-curing advanced thermogenic powders.
☑️ Liquid furnace color
Another type of furnace paint is electrostatic liquid coating.
Liquid electrostatic painting is done in a way that
The paint is sprayed onto the surface by the action of an electric field from the gun.
Of course, it should be noted that depending on the type of application, more equipment may be needed;
Like any other spray painting.
The application of liquid paint by electrostatics is a threefold process that is carried out as follows:
A primer must be applied (Zinc Polyester, Epoxy Barrier Primer, E Coating).
Apply the base color.
A protective coating is applied to the part.
Some products that are painted using liquid electrostatics,
There are cars, wooden furniture, metal structures, etc.
☑️ The benefits of electrostatic liquid coating
In most cases, parts are air dried.
Depending on the colors used, the drying time may be between 1 and 24 hours.
Only in a few cases can drying be done by heat.
In this case, a lower temperature than that used for powder coating should be required.
Electrostatic liquid painting has another advantage: changing colors is easy.
This is especially important for small and medium-sized manufacturing companies that may have only one or a few specific locations for painting;
Therefore, the color change is very important for them to be fully produced.
In general, the advantages of electrostatic liquid furnace paint can be summarized in the following cases:
Affordable
Easy to use
It does not require expensive equipment
Can be used in any area, not just your workplace
Equipment parts are easier and cheaper to find
A wide range of colors can be mixed
If needed, you can touch the desired part while painting
The cover layer is lighter
☑️ Specialty of operator in using furnace color
At the time of painting and working with various types of furnace paint, the expertise of the operator is another factor
It should be more strict.
In the case of powder coating, if operators do not clean the parts properly,
The entire process will fail.
So the surfaces must be completely smooth and polished and covered from the beginning.
