An adhesive is a compound material capable of joining two or more substrates together by surface adhesion and internal cohesion forces. It can form stable bonding joints after physical drying or chemical curing, widely used to connect various materials in industry and daily use.

Core Terms

• Adhesion: surface sticking force 附着力

• Cohesion: internal binding force 内聚力

• Curing: solidification process 固化

• Substrate: bonded material 基材
