The coil coating of a flat metallic substrate such as zinc-coated steel or aluminium has a number of advantages over painting the finished articles (commonly known as “post-painting”). These include:

• Wastage of the paint is virtually eliminated.
• The consistent application process allows a reduced paint film thickness, so using less paint.
• Paint drying and curing is carried out in a controlled way to dramatically cut emissions of harmful VOCs and to minimise overall energy consumption.

The environmental impact of the process has been quantified through an independently verified life cycle assessment and is shown to be lower than an equivalent post-painting process.

The prepainted product also allows fabricators and users of the product to eliminate cleaning, painting, and curing processes and so operate under simplified regulatory regimes.
