How to choose epoxy resins and additives?
Epoxy resins are generally used at the same time as additives to obtain application value. Additives can be selected according to different uses, commonly used additives are curing agent, modifier, filler, diluent, other. Among them, curing agent is an essential additive, whether it is used as adhesive, coating, castable, it is necessary to add curing agent, otherwise the epoxy resin can not cure. Due to the different performance requirements, there are also different requirements for epoxy resins and additives such as curing agents, modifiers, fillers and diluents.
Flexible epoxy resin preparation technology
Bisphenol A epoxy resin is widely used in various fields of national economy because of its good bonding property, mechanical strength and electrical insulation, but it is difficult to meet the increasingly strict requirements of engineering technology because of its brittleness and low impact strength structural defects. The traditional flexible group modified epoxy resin can improve the toughness of epoxy curing system to a certain extent, but it is still difficult to solve the requirement of engineering materials for ultra-high elongation at break (more than 80%). In order to solve the comm

Toughening modification method of epoxy resin
Epoxy resin (EP) is an important thermosetting resin formed by the reaction of EP oligomers with curing agents. According to the chemical structure and binding mode of EP groups, they are generally divided into five categories: glycerol amines, glycerol esters, glycerol ethers, aliphatic epoxides, and alicyclic epoxides. Due to the presence of a large number of EP groups in pure EP, the chemical crosslinking density of the cured structure is high, the molecular chain flexibility is low, and the internal stress is high, resulting in high brittleness, poor impact resistance, and poor fati
What are the main uses of epoxy resin?
What is epoxy resin? Epoxy resin is a high molecular polymer. The Molecular formula is (C11H12O3) n, which is the general name of a class of polymers with more than two epoxy groups in their molecules. It is the condensation product of Epichlorohydrin and bisphenol A or polyol. Due to the chemical activity of epoxy groups, various compounds containing active hydrogen can be used to open rings, solidify and crosslink to form a network structure, making it a thermosetting resin. Bisphenol A type epoxy resin not only has the largest output and the most complete variety, but also has a cont
Performance characteristics of epoxy resin
Generally speaking, epoxy resin structures contain hydroxyl and ether bonds, which give them high adhesion. Due to these polar groups, electromagnetic forces can be generated at adjacent interfaces. During the curing process, there is less chemical interaction with the curing agent, which can further generate hydroxyl and ether bonds. This not only has high cohesion, but also generates strong adhesion. Therefore, epoxy adhesive is suitable for various materials such as metal, plastic, glass, wood, etc., and materials such as fibers have strong bonding strength, commonly known as "universal adh
Epoxy adhesive with excellent performance
Bonding (Bonding, Bonding, Bonding) refers to the technique of using adhesives to bond the surfaces of homogeneous or heterogeneous objects together. It has the characteristics of continuous stress distribution, light weight, or sealing, and most processes have low temperatures. Adhesive bonding is particularly suitable for connecting complex components with different materials, thicknesses, ultra-thin specifications.
