RAL1023 traffic yellow electrostatic thermoset powder coating for Tool Boxes
Powder coating is a type of dry coating, which 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." The powder may be a thermoplastic or a thermoset polymer. It is usually used to create a hard finish that is tougher than conventional paint. Powder coating is mainly used for coating of metals, such as "whiteware", aluminium extrusions, and automobile and motorcycle parts. Newer technologies allow other materials, such as MDF (medium-density fibreboard), to be powder coated using different methods
Advantages and disadvantages of powder coating
There are several advantages of powder coating over conventional
liquid coatings:
- Powder coatings emit zero or near zero volatile organic compounds (VOC).
- Powder coatings can produce much thicker coatings than liquid coatings without running or sagging.
- Powder coating overspray can be recycled and thus it is possible to achieve nearly 100% use.
- Powder coating production lines produce less hazardous waste than conventional liquid coatings.
- Capital equipment and operating costs for a powder line are generally less than for conventional liquid lines.
- Powder coated items generally have fewer appearance differences between horizontally coated surfaces and vertically coated surfaces than liquid coated items.
A wide range of specialty effects is easily accomplished which would be impossible to achieve with other coating processes.

Food service areas.
Goods display, etc.
When thermoset powder is exposed to elevated temperature, it begins
to melt, flows out, and then chemically reacts to form a higher
molecular weight polymer in a network-like structure. This cure
process, called crosslinking, requires a certain temperature for a
certain length of time in order to reach full cure and establish
the full film properties for which the material was designed.
Normally the powders cure at 200°C (390°F) for 10 minutes. The
curing schedule could vary according to the manufacturer’s
specifications
