Classification of epoxy resin
The classification of epoxy resins has not yet been unified. Generally, they are classified according to strength, heat resistance grade and characteristics. There are 16 main types of epoxy resins, including general-purpose adhesives, structural adhesives, temperature-resistant adhesives, low-temperature-resistant adhesives, underwater, and wet surfaces. 16 kinds of glue, conductive glue, optical glue, spot welding glue, epoxy resin film, styrofoam, strain glue, soft material bonding glue, sealant, special glue, suspected curing glue, civil construction glue: At present, the classification of epoxy resin adhesives is distributed in the industry as follows:
1 According to its main composition, it is divided into pure epoxy resin adhesive and modified epoxy resin adhesive;
2 according to its professional use Divided into epoxy resin adhesives for machinery, epoxy resin adhesives for construction, epoxy resin adhesives for electronic eyes, epoxy resin adhesives for repairing, adhesives for transportation, adhesives for ships, etc.;
3 Construction according to them Conditions are divided into room temperature curing type glue, low temperature curing type glue and other curing type glue;
4 According to its packaging form can be divided into one-component glue, two-component glue and multi-component glue, etc.; There are other classification methods , Such as solvent-free glue, solvent-based glue and water-based glue. But at present, there are many applications based on component classification.
