Aluminium Powder Coating

Powder coating is applied as a free-flowing, dry powder. Unlike conventional liquid paint which is delivered via an evaporating solvent, powder coating is typically applied electrostatically and then cured under heat.

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 various metals including aluminium extrusions.

The powder coating process begins with a series of pre-treatments that clean the aluminium and prepare its surface for optimum adhesion.

Bar length profiles are loaded into baskets and manually processed through a number of tanks, before being loaded on to a conveyor.

The powder coating is applied via an automated process for the best results, before being cured in the oven at a temperature of 160 to 200 degrees C for around 20 minutes.

A wide range of colours and finishes are available depending on the products application and aesthetic requirements.
