Also called powder coating, it is a painting process used for coating metal parts of all kinds. It is a thermosetting coating, which therefore solidifies with heat.
Its application is carried out most often with a spray gun. You first apply a thin layer of powder paint – of various colors, finishes, and textures – and then you bake the piece in a specialized oven at 400 degrees Fahrenheit. The result is a durable and resistant coating.
Types of powder paint
Epoxy powder is mainly used for its anti-corrosion properties. Ideal for coating parts used in the composition of pipes, tanks, and valves. Its corrosion resistance makes it the best choice for marine environments. We also appreciate its resistance to heat and chemicals.
Hybrid Epoxy Polyester Powder Coating
An interesting compromise for ultraviolet (U), harsh climatic conditions and corrosion resistance.
Polyester Powder Coating
The main properties of this type of powder coating are its resistance and flexibility. Its high resistance to ultraviolet rays reduces the risk of discoloration due to sunlight and its durability under various climatic conditions makes it suitable for outdoor use on fences, outdoor furniture and agricultural equipment, among others. It’s a great choice for indoors and outdoors.
Common Uses for Industrial Powder Coating
This industrial process is reserved for professional, commercial and industrial uses because of its complexity and the expertise and equipment required. Electrostatic powder coating can be applied to large formats of metal parts, as well as large quantities. It is used among others in the following contexts:
Manufacturing of agricultural equipment
Manufacture of aluminum doors and windows
Powder paint has many possible applications. Contact us to find out more about the possibilities.
Advantages of electrostatic powder coating
Reduced environmental impact
Since it doesn’t require the use of any solvent, it is an environmentally friendly process in comparison to other coating application methods. Its LEED approval makes it a method of choice for use in architecture and building design. The powder coating also complies with the RoHS standard, limiting its impact on public health and the environment. It is also free of VOCs.
Speed of application
Electrostatic powder coating is a monolayer technique that requires no drying time. It is a fast method that allows us to produce large quantities and meet tight deadlines, especially in large industrial and commercial mandates.
Wide variety of coatings
Powder coating is a coating method that offers a variety of colors, finishes, and textures. It, therefore, provides great control over the aesthetics and design of the finished products.
Key condition for the success of electrostatic powder coating: surface preparation
Surface preparation is the most important step since it is a crucial factor that determines the uniformity and durability of the coating after its application. The preparation of the piece can be done in two ways:
Oxyblast (aluminum oxide sandblasting)
Shotblasting or glass blasting
The mechanical operation chosen will ensure the bare metal is ready to receive the powder.
To ensure the quality of the final result, a pre-treatment by chemical soaking is then carried out in 5 phases using zinc phosphate.
