What are the effects of prolonged exposure to de-icing salts on WPC?
Prolonged exposure to de-icing salts can significantly impact the performance and longevity of Wood-Plastic Composite (WPC) materials. De-icing salts, commonly used in cold climates to melt ice, can cause chemical reactions that weaken the polymer matrix in WPC, leading to reduced structural integrity. Over time, this exposure may result in surface degradation, discoloration, and increased brittleness. Additionally, moisture absorption can accelerate these effects, further compromising the material's durability. To mitigate damage, regular cleaning and protective coatings are recommended for WPC surfaces exposed to de-icing salts. Understanding these effects helps in making informed decisions for outdoor applications like decking and fencing.
