Metallic parts and plastic parts are commonly bonded in toys, machine components, and electronic components, among other applications. When bonding metal to plastic, the adhesive typically needs to meet three key requirements:

1. Fast-drying; using fast-drying glue is more convenient and can improve production efficiency.

2. No discoloration, as it may affect the product's appearance.

3. Eco-friendly, these products are generally used for daily commodities.
