POWDER COATING

What is Powder Coating?

Powder coating is a type of coating that is applied as a dry powder.

The powder is a mixture of finely ground particles of pigment and resin, which is electrostatically charged and then sprayed onto a surface to be coated.

The charged powder particles are attracted to the grounded surface, where they are then cured under heat to form a hard, durable finish.

This process is often used for coating metal surfaces, as it provides a more consistent and durable finish compared to traditional liquid coatings.

Advantages of Powder Coating

DURABILITY Powder coating creates a thick, hard finish that is more resistant to chipping, scratching, and fading than liquid coatings.

CONSISTENCY: Powder coating provides a more consistent finish than liquid coatings, as there is less overspray and fewer runs or drips.

VARIETY OF COLOUR & FINISH OPTIONS: powder coating can be formulated to achieve a wide range of colours and finishes, including gloss, matte, and textured.

COST-EFFECTIVE: Powder coating is often less expensive than liquid coatings, as it requires less material and has a lower labour cost.

ENVIRONMENTALLY FRIENDLY: Powder coating does not emit volatile organic compounds (VOCs) and does not involve the use of solvents. This makes the process more environmentally friendly than traditional liquid coatings.

VERSATILITY: Powder coating can be applied to a wide range of materials, including metals ,plastics, and ceramics.

EFFICIENCY: The process of powder coating is faster than traditional liquid coating methods, which helps to reduce labour costs and increase production efficiency.

RECYCLABLE: Powder coating can be recycled and can be used again, which help to reduce waste and costs.

The process typically involves the following steps:

 

  • Surface preparation: The surface to be coated is cleaned and sandblasted to remove any rust, dirt, or other contaminants.
  • Applying the powder: The powder is electrostatically charged and then sprayed onto the surface using a spray gun.
  • Curing: The coated surface is then heated to a high temperature,typically between 150-200°C, to cure the powder and form a hard finish. Inspection and
  • Quality control: After curing, the part is inspected for any defects and is then packaged for shipment.
