POWDER COATING VS PAINTING
Dry powder is shot through an electrostatic gun. Liquid paint is dispensed in a fine spray. Both processes are electrostatically charged but painting is less effective. Some textures can be attained equally well by powder coating or wet paint, but others are easier to achieve with a particular medium.
- Textured finishes are much easier to attain with powder coats. Thinner powder coats are naturally more textured, while thicker layers are smoother. It is technically possible to attain a high-gloss finish with powder coating, but it is much easier with wet paint.
- Powder coating has much strength, but wet paint is the unequivocal winner when it comes to color matching.
- Custom colors of liquid paint can be mixed on-site, and with a high degree of precision, by almost any paint supplier. A blue and red pigment can be mixed to produce purple paint. There is no solvent in powder coating, so an attempt to blend blue and red powder will just create a blue and red speckle pattern. Powder coating is usually produced in large batches of standard colors because it is hard to color match.
- Wet paint technology has been around a lot longer, so the equipment and materials are more widely available.
- Powder coating is safe to store and apply. Wet paint is dangerous for several reasons. First of all, it’s flammable. Careless storage can easily lead to a dangerous chemical fire. Wet paint emits volatile organic compounds (VOCs). Long term exposure to VOCs, especially in enclosed spaces, causes respiratory irritation and compounding health problems. VOCs are also a major source of industrial pollution. Powder coat don’t emit any VOCs, and are completely free of the associate health and safety risks because powder coatings don’t contain any fluids to evaporate.
- Powder coating provides better performance than wet paint. It is more resistant to chipping, scratching, and other wear.
