What is Powder Coating?
Powder coating is a dry finishing technique that has grown in popularity since its introduction to North America in the 1960s. Since then, it has been used on a wide range of products, accounting for around 15% of the overall industrial finishing sector.
Powder coatings are more frequently used by businesses that want a high-quality, long-lasting finish that improves production efficiency and reduces waste.
Powder coatings, which are often utilized as protective (anti-graffiti) and decorative treatments, come in an almost endless spectrum of hues and textures. Technological advancements have resulted in exceptional performance.
How Powder Coating Works
Powders are formed from polymer resins, curatives, pigments, levelling chemicals, flow modifiers, and other additives that are melted down and cooled.
A method known as ESD is used to coat metal substrates with a powder coating. The spray gun in this application technique charges the powder particles with an electric charge and draws them toward the grounded surface.
The parts are placed in a curing oven and heated to promote the paint’s chemical reaction and formation of long molecular chains with high cross-link density. These molecular strands are extremely durable. Powder coatings may also be used on non-metallic substrates such as polymers and medium-density fiberboard (MDF).
Powder coating is sometimes used in the fluidized bed procedure.
The parts are dipped in a hopper of fluidizing powder and the coating melts, running off the part. Depending on the amount and temperature of the components, post-cure may be necessary.
Powder coatings are simple to apply and environmentally beneficial, regardless of the application process. They’re also cost-effective and durable!
The durability of Powder Coating
Powder coating is a high-end finish that may be found on thousands of items you use regularly. Powder coating protects not just the most robust, durable equipment, but also the tools and everyday objects on which you rely. It gives a more long-lasting look than liquid paint while still being both attractive and durable.
The coating on powder-coated parts is more resilient to deterioration as a result of the impact, wetness, chemicals, UV light, and other harsh weather conditions. As a consequence of this, scratches, cracking, abrasions, corrosion are all more likely.
It’s tough. It has a lovely finish. And it holds up for a long time. Powder coating, which has environmental benefits, also contributes to its longevity.
