Powder coating is a type of coating that is applied as a free-flowing, dry powder. The main difference between a conventional liquid paint and a powder coating is that the powder coating does not require a solvent to keep the binder and filler parts in a liquid suspension form. The coating is typically applied electrostatically and is then cured under heat to allow it to flow and form a "skin". It is usually used to create a hard finish that is tougher than conventional paint.
Advantages of powder coating:
While powder coatings have many advantages over other coating processes, there are some disadvantages to the technology. While it is relatively easy to apply thick coatings which have smooth, texture-free surfaces, it is not as easy to apply smooth thin films. As the film thickness is reduced, the film becomes more and more orange peeled in texture due to the particle size and glass transition temperature (TG) of the powder. Also powder coatings will break down when exposed to UV rays between 5 to 10 years.
The powder coating process:
The powder coating process involves three basic steps:
Is it Environmentally Friendly?
Powder coating is an environmentally friendly process unlike solvent-based wet paint systems. With stricker EPA regulations, powder coating is quickly becoming the technology of choice. Since the powder coating process does not use solvents in any way, VOC emission problems are eliminated.
What Colors Do You Offer?
B & B Powder Coating offers hundreds of "stock colors", including metallics, textures and special effects. B & B Powder Coating can assist you in matching and/or choosing the correct coating and color for your application.
What Can Be Coated?
Anything metal! It is ideal for the following items:
Can I Use Body Filler?
The high oven temperature makes the use of plastic and resin body fillers impossible. Metal fillers such as JB Weld, Lab Metal, All Metal, etc.
