Epoxy resin adhesive generally refers to the adhesive made of epoxy resin as the main body, and epoxy resin adhesive generally should also include epoxy resin curing agent, otherwise the adhesive will not cure. Epoxy resin adhesives can be classified according to their main components, professional uses, construction conditions and packaging forms. Epoxy resin glue is divided into soft glue and hard glue. Epoxy soft adhesive: It is a liquid, two-component, soft, self-drying soft adhesive, colorless, transparent and elastic, and will automatically recover after the surface is slightly scratched. Suitable for the decoration of signs such as polyester, paper and plastic. Epoxy resin hard glue: liquid, two-component hard glue, colorless and transparent, suitable for metal signs, and can be used to make crystal buttons, crystal bottle caps, crystal wooden combs, crystal handicrafts and other high-end decorations.

At present, the classification of epoxy resin is not uniform, generally according to strength, heat resistance grade and characteristics. The main varieties of epoxy resin are 16, including general adhesive, structural adhesive, temperature-resistant adhesive, low-temperature resistant adhesive, underwater and wet surface adhesive, conductive adhesive, optical adhesive, spot welding adhesive, epoxy resin film, foam adhesive, strain adhesive, soft material adhesive, sealant and special adhesive. There are several ways to classify epoxy resin adhesives in the industry: according to their main components, they are divided into pure epoxy resin adhesives and modified epoxy resin adhesives; According to their professional uses, they are divided into mechanical epoxy adhesives, building epoxy adhesives, electronic eye epoxy adhesives, repair epoxy adhesives, transportation adhesives, and ship adhesives. According to its construction conditions, it can be divided into normal temperature curing adhesive, low temperature curing adhesive and other curing adhesives; According to its packaging form, it can be divided into one-component adhesive, two-component adhesive and multi-component adhesive.
