1. Selection based on bonding materials: Different materials have different surface characteristics, requiring the selection of a matching PU adhesive type. For example, porous materials are best suited for adhesives with lower viscosity.
2. Selection based on the application environment: Consider factors such as temperature, humidity, and chemical media. High-temperature environments require heat-resistant PU adhesives, while humid environments favor moisture-curing adhesives.
3. Selection based on performance requirements: When there are special requirements for bond strength, flexibility, or curing speed, a PU adhesive with an appropriate formulation should be selected.
4. Selection based on construction conditions: Consider existing equipment, operating skills, and time constraints. Slower-curing types can be used for manual operations, while fast-curing types are suitable for automated production lines.
