A polyester powder mixed with colour pigments are ionized through a pressure gun and sprayed onto the chemically pre-treated mill finish profiles, which are earthed and hung on a conveyor. The profiles which pass through the polyester powder ‘cloud’ are then subjected to deposits of powder onto the profile in a controlled manner to give a uniform layer. This profile with the dry powder on its surface is then passed through an oven for curing. The cured coloured powder provides a lush durable texture to the surface. Various types of powder and pigments provide a large range of colour shades and gloss texture to Polyester powder coating, also known as colour coating on aluminum, is a solvent-free, durable, factory-applied coating for aluminum substrates. It is a thermosetting coating where the resin cross links after stored at around 200°C (curing).
