Para quem anda aqui para aprender algo fica aqui a explicação científica sobre o que são os adesivos estruturais utilizados nos mais variados ramos industriais:
2 Structural Adhesive
A structural adhesive can be defined as a material used to transfer loads between adherends in service environments that are typically load bearing, i.e., an adhesive is a substance that is capable of holding materials together by surface attachment. Since a structural adhesive is capable of transmitting loads from one joint to another in a uniform manner, these adhesives permit the fabrication of structures that are mechanically equivalent or superior to conventionally fastened assemblies. In addition to improved reliability, the use of structural adhesives can reduce cost and weight.
