Ask for some introduction of thermosetting materials, it is best to have advantages and disadvantages are issued
Characteristics of epoxy resins (usually bisphenol A epoxy resins)1., the application of epoxy resin is very low value, it needs to be used in conjunction with the curing agent, it has practical value.2. high bonding strength: in synthetic adhesive, the adhesive strength of epoxy resin is in the forefront.3. curing shrinkage is small, in the adhesive, the shrinkage of epoxy resin is the smallest, which is also the reason for the high adhesion of epoxy resin adhesive
The concept of epoxy resin:Epoxy resin refers to the macromolecular chain structure containing two or more than two epoxy groups of generic compounds, belongs to thermosetting resin, representative resin is bisphenol A epoxy resin.
Chemical resistance: the ether group, benzene ring and fatty hydroxyl group in the curing system are not susceptible to acid and alkali corrosion. In the sea water, oil, kerosene, 10%H2SO4, 10%HCl, 10%HAc, 10%NH3, 10%H3PO4 and 30%Na2CO3 can be used in two years; and in the 50%H2SO4 and 10%HNO3 soaking at room temperature for half a year; 10%NaOH (100 DEG C) for a month, performance remains unchanged.
