What is electrostatic spray powder coating?
Electrostatic spray applies charged powder particles to a grounded metal surface using a spray gun.
The electrostatic attraction ensures even coverage and reduces overspray.
How does fluidised bed powder coating work?
Preheated parts are dipped into a bed of fluidised powder, which melts and adheres to the surface.
This method is ideal for consistent coating of small or complex parts.
Can powder coating be applied by hand?
Yes, hand spraying is used for touch-ups, small parts, or complex assemblies.
Automatic or robotic systems are preferred for large-scale, consistent results.
What are the advantages of electrostatic application?
Electrostatic spraying provides even coverage, minimal waste, and faster application.
It also allows powder to reach corners and recesses more effectively than conventional methods.
What thickness can powder coating achieve?
Typical powder coating thickness ranges from 60 to 120 microns.
Multiple layers or specialty powders can increase thickness for enhanced durability or texture.
Are there special considerations for complex shapes?
Yes, corners, recesses, and overlapping surfaces may require adjustments in powder flow and electrostatic settings.
Pre-heating or multiple passes can help achieve uniform coverage.
Can powder coating be applied to welded metal parts?
Yes, welded assemblies can be coated after removing weld residues and properly preparing the surface.
Care must be taken to avoid uneven coating or overheating at weld joints.
How does powder coating prevent runs and drips?
Powder coatings are dry, so they do not sag or drip like liquid paint.
When cured, they form a smooth, even layer, even on vertical surfaces.
Explain how a Powder Coating Spray Gun works
A powder coating gun charges the powder electrostatically and sprays it onto the grounded workpiece.
The charged particles are attracted to the surface, sticking until cured in the oven for a durable finish.
Can powder coating be applied to non-metal surfaces?
While powder coating is primarily designed for metals like steel and aluminium, some specially formulated powders can coat non-metal surfaces such as certain plastics, MDF, and composite materials.
These applications often require a primer or surface treatment to ensure proper adhesion and durability.
