What are the effects of ozone exposure on the surface integrity of resin-based outdoor planters?

Ozone exposure significantly affects the surface integrity of resin-based outdoor planters, leading to visible and structural damage over time. Prolonged exposure to ozone, a reactive gas present in polluted air, accelerates the degradation of resin materials. Common effects include discoloration, loss of gloss, and surface cracking due to oxidative stress. Additionally, ozone weakens the polymer chains in resin, reducing flexibility and making planters more prone to brittleness and breakage. UV radiation often exacerbates these issues, causing further fading and material breakdown. To mitigate ozone damage, manufacturers may use UV stabilizers and anti-oxidant additives, but long-term outdoor use still poses challenges. Regular maintenance and protective coatings can help extend the lifespan of resin planters in ozone-rich environments.
