What are the challenges in bonding different plastics together in modular outdoor ottomans?

Bonding different plastics together in modular outdoor ottomans presents several challenges. First, material compatibility is a major issue, as not all plastics adhere well to each other due to differences in chemical composition and surface energy. Second, outdoor conditions like UV exposure, temperature fluctuations, and moisture can weaken adhesives over time, reducing durability. Third, selecting the right adhesive is critical—some may not withstand mechanical stress or environmental factors. Additionally, surface preparation, such as cleaning and roughening, is essential for strong bonds but can be labor-intensive. Finally, aesthetic concerns arise, as visible adhesive lines or discoloration may affect the ottoman's appearance. Addressing these challenges requires careful material selection, advanced adhesives, and precise manufacturing techniques.
