Best Coatings for Outdoor Applications

Choosing the best plastic coating for any project is a balancing act weighing such aspects as functional requirements, appearance, budget, and safety and regulatory guidelines. Performance under anticipated environmental conditions will also influence your choice of material.

UV Exposure

Among the biggest threats to lasting powder coating is exposure to the ultraviolet rays of the sun. Extended UV exposure can cause chalking (when coatings develop a faded, powdery, even flaky surface) as pigments and other components in the coating formulation start to lose their bond with the surface. Most coatings offer reasonable resistance to UV light, including nylon, and polyethylene. Many epoxy formulations do not perform well over time with prolonged UV exposure. Plastisol and vinyl have high tolerance for UV exposure when additives are included in their formulations. Polyolefin, polyester, and Halar, however, are standouts for UV tolerance, making them popular as a coating for playground equipment, outdoor furniture, and fencing.

Other Outdoor Exposures

Powder coatings provide excellent protection against numerous common outdoor exposures, creating a durable barrier between vulnerable parts and the elements. The best protection against harsh weather includes:

• Proper cleaning and surface preparation
• Careful coating material selection
• Thorough coating appropriate to coating material and the part or product being protected
• Complete heat curing
• Appropriate care, cleaning, and maintenance

Working with an experienced powder-coating team who can help you choose the best material for coating your project can mean the difference between durable, long-lasting results and a poor-quality finish that doesn't offer adequate protection.
