What kind of epoxy resin in the beauty joint agent-beauty joint agent factory

Epoxy resin is the general term for a class of polymers containing more than two epoxy groups in the molecule. It is a polycondensation product of epichlorohydrin and bisphenol A or polyol. Due to the chemical activity of epoxy group, a variety of compounds containing active hydrogen can be used to open the ring, cure and crosslink to form a network structure, so it is a thermosetting resin. Bisphenol A epoxy resin has the largest output and the most complete varieties, and new modified varieties are still increasing, and the quality is constantly improving. The basic classification and classification standard of epoxy resin The classification of epoxy resin has not yet been unified. It is generally classified according to strength, heat resistance grade and characteristics. There are various types of epoxy resin, including general-purpose adhesive, structural adhesive, high-temperature adhesive, and low-temperature resistance. Glue, glue for water and wet surface, spot welding glue, epoxy resin film, strain glue, soft material bonding glue, sealant, special glue, latent curing glue, civil construction glue. There are several classifications of epoxy resin adhesives in the industry as follows: According to its main composition, it is divided into pure epoxy resin adhesives and modified epoxy resin adhesives; Professional uses are divided into epoxy resin adhesives for machinery, epoxy resin adhesives for construction, electronic epoxy resin adhesives, epoxy resin adhesives for repairs, and adhesives for transportation and ships; Its construction conditions are divided into normal temperature curing glue, low temperature curing glue and other curing glue; According to its packaging form, it can be divided into one-component glue, two-component glue and multi-component glue, etc.; there are other Sub-methods, such as solvent-free glue, solvent-based glue and water-based glue, etc. However, there are many applications based on component classification.
