What are the effects of prolonged exposure to saltwater mist on WPC?

Prolonged exposure to saltwater mist can significantly impact the performance and durability of Wood-Plastic Composite (WPC). Saltwater mist, common in coastal environments, accelerates the degradation of WPC by causing moisture absorption, swelling, and eventual weakening of the material. Over time, this exposure may lead to discoloration, surface erosion, and reduced structural integrity. Additionally, the salt crystals can embed into the composite, promoting microbial growth and further deterioration. To mitigate these effects, manufacturers often apply protective coatings or UV stabilizers. Regular maintenance and choosing high-quality WPC with enhanced resistance are recommended for long-term use in salty conditions. Understanding these effects helps in selecting the right materials for coastal applications.
