1. Unstructured adhesives (or universal adhesives)
A component that is mainly used for adhesive bonding without force or force. It is less stringent on mechanical properties than structural adhesives, but other properties must meet certain requirements.
2. Special adhesive
It is mainly used for some connectors with special performance requirements, such as conductive adhesives, thermal conductive adhesives, magnetic conductive adhesives, spot welding adhesives, photosensitive adhesives, compression adhesives, strain gels, underwater adhesives, hydrophobic adhesives, liquid sealants, etc.
