Adhesive is a substance with good adhesion properties. Through the adhesion and cohesion from the surface adhesion to play the role of connecting objects.

 

Substance introduction

Organic or inorganic, natural or synthetic substances that can connect the same or two or more homogeneous or heterogeneous parts (or materials) together with sufficient strength after curing, collectively referred to as adhesives or Adhesives, adhesives, and conventionally referred to as glue.
 

 

 

Divided into natural polymer compounds (starch, animal skin rubber, bone glue, natural rubber, etc.), synthetic polymer compounds (epoxy resin, phenolic resin, urea resin, polyurethane and other thermosetting resins, polyvinyl acetal, perchloroethylene resin, etc. Thermoplastic resin, and synthetic rubber (such as neoprene, nitrile rubber), or inorganic compounds (silicate, phosphate, etc.). According to the requirements of use, curing agents, accelerators, reinforcing agents, ene release agents, fillers, etc. are often incorporated into the adhesive. Classified by purpose, it can also separate warm glue, sealant, structural glue, etc. There are room temperature curing adhesives and pressure-sensitive adhesives according to the use process. Adhesive can be used to connect dissimilar materials and sheet materials, and the stress distribution at the joint is even. Epoxy resin, neoprene and sealant are commonly used in container manufacturing and repair.
 

In recent years, organic adhesives have been used more and more widely, and the bonding technology has also matured, and has become one of the three major connection technologies of bonding, welding and mechanical connection.
