What are the effects of prolonged exposure to pesticides on WPC surfaces?

Prolonged exposure to pesticides can significantly impact Wood Plastic Composite (WPC) surfaces, leading to various adverse effects. Over time, chemical interactions between pesticides and the composite material may cause surface degradation, including discoloration, fading, or staining. The plastic and wood fibers in WPC can react differently to pesticides, potentially weakening the structural integrity. Some pesticides may accelerate weathering effects, making the surface more brittle or prone to cracking. Additionally, certain chemicals might alter the hydrophobic properties of WPC, reducing its resistance to moisture absorption. The extent of damage depends on factors like pesticide concentration, exposure duration, and WPC composition. Regular cleaning and protective coatings can help mitigate these effects. For outdoor WPC applications in agricultural or pest-prone areas, selecting pesticide-resistant formulations is advisable to ensure long-term durability.
