Why is Powder Coating Better than Liquid Painting?

If you are a manufacturer of metal products, parts or components, you will probably have to decide which process is better for your company: liquid painting or powder coating. While many manufacturers view wet painting as the “traditional” finishing process, more companies in the automotive, appliance and construction industries are discovering the advantages powder coating offers.

Why is Powder Coating a Smarter Option?

Powder coating is a metal finishing technique that involves the electrostatic application of a dry powder. The coated part or component is then placed in a curing oven to finalize the coating and promote adhesion. The curing process enables the coating to flow and form a protective “skin” on the surface of the workpiece. The powder can consist of either a thermoset or thermoplastic polymer material.

Powder Coating Benefits

Powder coating can produce thicker finishes than conventional paint and will not produce dripping, running or sagging. Unlike paint, powder coatings do not contain or emit harmful VOCs. It is also possible to recycle the overspray, which reduces the amount of material waste. From an aesthetics perspective, powder coated surfaces typically have fewer appearance deficiencies. Like paint, powder coatings come in numerous attractive colors.

Powder Coating Drawbacks

There are few disadvantages to selecting powder coating as a finishing technique. If you require a custom color for your workpieces, it can be more difficult and costly to create with powder coating than paint. Powder coating also does not work well with materials other than metals — for instance, the intense heat produced by a curing oven can melt many natural or synthetic rubber materials.

Liquid Paint vs. Powder Coating: Which One Makes Sense for Your Manufacturing Applications

More companies are making the transition to powder coating to reduce operating costs, improve long-term product performance and durability, achieve higher safety standards and leave less of a carbon footprint. If speed is a factor, powder coating can be a necessity, as it eliminates the extensive drying time required during the wet painting process. This enables manufacturers to meet their increasingly tight production deadlines.
