Polyester Powder Coating Explained

Polyester Powder Coating Explained

When specifying fencing for your site, along with aesthetics and security, the finish should be carefully considered. Budget, climate and location can all influence which finish will be most suitable for your requirements. Polyester powder coating (PPC) is just one of the high-quality finishes we offer, so we’ve answered a few questions to help you decide if powder coating is the best option for you:

What is polyester powder coating?

Polyester powder coating is a type of material refinishing that provides a robust alternative to conventional paint; essentially, it is paint in a powder form. Providing an inherently strong finish, it can be applied to any surface that will not be affected by heat.

How is it applied?

Using compressed air, an electrostatic gun pushes the powder onto the object to be painted, which is kept grounded, to ensure a uniform application and therefore better performance. Positively charging the powder ensures the paint is attracted to the surface and, once fully covered, the object is baked in an oven where a chemical reaction causes the powder to form a skin that cools into a hard finish.

Why should I specify powder coated products?

Aesthetically speaking, powder coating delivers a thicker coating than traditional paints, without any running or dripping, resulting in minimal difference in appearance between horizontally and vertically coated surfaces. A comprehensive range of colours provides specifiers with flexibility in terms of design and appearance.

Along with being visually appealing, the resulting finish is high-quality, high-performance and durable. Designed for external use, the powder coating has excellent colour and gloss retention, which are paramount with frequent exposure to the sun and inclement weather.

Powder coating is an especially exceptional choice for metal parts because of its strength, durability and resistance to abrasion, fading and wear.

What are the environmental benefits?

Significantly, solvents aren’t used during the coating process, so fewer volatile organic compounds are emitted than with conventional paint, making the process more environmentally-friendly.

Waste is kept to a minimum through recycling and reusing any overspray produced during the powder application, and powder coatings also enjoy shorter processing times than liquid coatings, reducing lead time, space and energy.
