Powder painting is a process of painting with dry powder paint that is given a negative electrostatic charge (10,000-90,000 volts). Sometimes powder painting is also called dry painting. After coating the object with paint, it is put into an oven, where the paint melts to cover the surface evenly. In the oven the chemical compounds in the paint powder react with each other and polymerize to improve the properties of the paint. A powder coated surface is characterized by hardness, color, attractiveness, durability, high quality, resistance to scratches and environmental effects. Wet paint requires a solvent, while powder coating does not. This creates a harder a surface layer that better protects the object’s surface from the effects of the environment.
Powder coating itself consists of 3 main processes:
Surface preparation – when the surface is cleaned, chemically treated, if necessary, sandblasted and prepared for painting. Surface powder coating – when paint is sprayed onto the surface using professional equipment in our booth. In a heating oven, where the paint melts to completely cover the surface of the object.
Advantages of powder coating:
- Protects the surface from rust
- Contains no toxic substances
- Lots of options to choose from
- The longest lasting color
- Extra long-lasting coverage
- Contains no harmful volatile organic compounds
- Can be covered with a much thicker layer than ordinary wet paint
- Paints are used economically
- Paints are recycled as needed
- Less environmentally harmful production compared to liquid paints
- Highly resistant to cracking, scratching, chipping, scratching, fading
- Suitable for steel, galvanized metal, aluminum, steel, brass, copper, bronze, titanium, lead, etc.
- Perfectly and fully covers any details
- Protects the surface from UV rays
With special paints and technology, you can paint ceramics, plastic, porcelain, MDF panels, glass and even specially prepared wood.
Differences between powder and wet painting
| Powder coating | Liquid coloring |
|---|---|
| Appeared in the 20th century. in the middle - this was due to the invention of paint powder | It has been used for 40 000 years |
| Cheaper | More expensive - often requires additional surface preparation, more work and application of several layers to achieve a satisfactory result |
| Faster | Slower |
| A thicker layer of paint | A thin layer of paint |
| Can be used on heat-resistant surfaces | Can be used on all surfaces |
| Evenly coated surface | The smoothness of the surface coating depends on the professionalism of the painter and the surface coating |
| More resistant to environmental influences | Not recycled, produced using harmful chemicals |
| More resistant to environmental influences | A thin layer of paint does not allow you to get the same resistance as when painting with powder paint |
| A large selection of effects and colors | Large selection of colors |
| Both horizontal and vertical surfaces are coated equally | It is extremely difficult to obtain completely uniform coverage |
