What are the ingredients of epoxy Ab adhesive? What is the specific composition of Ab glue?

1、 epoxy resin ab rubber composition

Epoxy resin AB adhesive refers to a general term for a three-dimensional cross-linked curing compound that contains two or more epoxy groups in a molecular structure and can be formed under appropriate chemical reagents and appropriate conditions. There are many kinds of them, and according to their chemical structure, they can be divided into glycidyl ethers, glycidyl esters, glycidyl amines, alicyclic epoxies, epoxies containing inorganic elements, and new epoxies (Hyne epoxies, imide epoxies, etc.). Among all kinds of epoxy resins, bisphenol A epoxy resin is one of the most productive and widely used varieties. According to its different molecular weight can be divided into low, medium, high, ultra-high molecular weight epoxy resin (polyphenoloxy resin). The low molecular weight resin can be cured at room temperature or high temperature, but the high molecular weight epoxy resin must be cured at high temperature, and the ultra-high molecular weight polyphenoloxy resin does not need the help of curing agents, and can form a tough film at high temperatures.


2、what is the specific composition of ab glue

AB rubber is mainly composed of polyacrylates and epoxy resins. Generally, AB adhesives are divided into two groups, one group is divided into the small molecule state of the polymer, and the other group is divided into the curing agent and the filler. The curing agent is mixed into the polymer to trigger the polymerization reaction, and the filling material plays a role in adjusting the reaction speed and the physical properties of the solidified colloid.

AB glue is another name for two liquid mixed hardening glue, one liquid is this glue, one liquid is hardener, two liquid phase can be mixed to harden, it does not need to rely on temperature to harden, so it is a kind of normal temperature hardening glue.
