What is Powder Coating?

Powder coating is a relatively new form of painting, developed over the past 20/30 years from plastic to powder paint.

It is extremely environmentally friendly, because the over spray can be reused and with no solvents in powder paint, there is no pollution to the air we breathe.

The technology involves applying dry, powdered organic coatings to metals by means of electrostatic powder spray guns.

Powdercoat adheres to the article until transferred to a baking oven where the baking process transforms the powder into a smooth, continuous and durable coating that is designed to provide the right combination of protective and decorative properties. Cleaning is simple. Wash down with a wet sponge & mild detergent. These days your fridge freezer & washing machine are all powder coated.

Cost

 

Is it expensive? NO. The cost of powder coating to normal wet painting is similar and in many cases is much cheaper when done in bulk. It costs less to apply one coat of Powder than to apply equivalent thickness of wet paint.

Many and varied uses

Can be used for fencing, handrails, gates, indoor and outdoor furniture, architectural extrusions (shop fronts etc.) wheel trims, bikes, bull bars,  signs, roof racks, in fact almost any metal

Advantages

 

Higher resistance to corrosion through weather, acids, alkalis & solvents. Flexibility, hardness, higher resistance to impact, (chip or abrasion) Superior protection & is much more resistant than other paints so extends the life of everything coated, which in turn lowers maintenance costs.

Primers are not always necessary but if necessary then the zinc rich epoxy primers add a longer lasting finish to mild steel that is subject to the weather. There are no runs or drips as with wet paint.

New innervations are now being used on coating glass for kitchen backings.

Disadvantages are few

 

The powder is generally applied only to metals.

The size of the object to be coated is limited to the oven size.

Very thin coats are harder to obtain.
