Basic classification of epoxy resins

Release time:


Classification standard

At present, the classification of epoxy resins has not been unified. Generally, they are classified according to strength, heat resistance grade and characteristics. There are 16 main varieties of epoxy resins. Including general adhesive, structural adhesive, high temperature resistant adhesive, low temperature resistant adhesive, water and wet surface adhesive, conductive adhesive, optical adhesive, spot welding adhesive, epoxy resin film, foam adhesive, strain adhesive, soft material bonding adhesive, sealant, special adhesive, latent curing adhesive, civil construction adhesive 16 kinds.

Several classifications

The classification of epoxy resin adhesives in the industry is also divided into the following ways:

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, it is divided into mechanical epoxy resin adhesives, architectural epoxy resin adhesives, electronic epoxy resin adhesives, epoxy resin adhesives for repair, transportation adhesives, ships and so on;

3. According to its construction conditions, it is divided into normal temperature curing type glue, low temperature curing type glue and other curing type glue;

4. According to its packaging form, it can be divided into single-component glue, two-component glue and multi-component glue, etc.

There are other methods, such as solvent - free glue, solvent - based glue and water - based glue. However, the classification of components is more applied.
