What adhesives are compatible with bonding WPC to metal components in modular outdoor sofas?

When assembling modular outdoor sofas, bonding WPC (Wood-Plastic Composite) to metal components requires adhesives that ensure strong, durable, and weather-resistant connections. Here are the top adhesive options:

1. Polyurethane Adhesives: Known for their flexibility and waterproof properties, polyurethane adhesives create a strong bond between WPC and metal, ideal for outdoor use.

2. Epoxy Resins: Offering high strength and chemical resistance, epoxy adhesives are excellent for load-bearing joints but may require surface preparation.

3. Acrylic-Based Adhesives: These provide fast curing and good UV resistance, making them suitable for outdoor furniture exposed to sunlight.

4. Silicone Adhesives: While less rigid, silicone adhesives excel in sealing and bonding uneven surfaces, accommodating thermal expansion.

For optimal results, clean and roughen both surfaces before application, and follow the manufacturer’s curing instructions. Choose adhesives labeled for outdoor use to ensure longevity against moisture and temperature changes.
