What WPC additives enhance resistance to barbecue grease stains?
Wood-plastic composites (WPC) are popular for outdoor applications like decking and furniture, but they can be vulnerable to stubborn barbecue grease stains. To enhance resistance, specific WPC additives are used. Lubricants like stearates improve surface smoothness, reducing grease penetration. UV stabilizers, such as hindered amine light stabilizers (HALS), prevent degradation that can make surfaces more porous. Nano-sized fillers, including silica or clay, create a denser matrix that repels grease. Additionally, hydrophobic additives like fluoropolymers form a protective barrier. Combining these additives ensures WPC materials remain stain-resistant and easy to clean, even after exposure to barbecue spills.
