Definition And Application Of Waterborne Epoxy Resin

Jul 08, 2020

Aqueous epoxy resin generally refers to an emulsion or aqueous dispersion formed by the epoxy resin dispersed in water in the form of particles, droplets or colloids. In addition to the advantages of ordinary epoxy resins, the modified water-based epoxy resin coatings and adhesives also have environmental protection characteristics. Water-based epoxy resins usually exist in the form of emulsions. Therefore, the emulsification method of water-based epoxy resins is studied Has a very important meaning.


  All compounds containing epoxy groups are collectively called epoxy compounds. Epoxy resin refers to a class of high polymers containing two or more epoxy groups in the molecular structure of epoxy compounds. Because of the chemical activity of epoxy groups, 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 classified as thermosetting resin.


Water-based epoxy resin has some shortcomings, but it can be improved by certain means. The reasonable choice of water-based epoxy resin base material, curing agent and various modifiers and additives can be prepared with different properties. Waterborne epoxy resin coatings and adhesives. There have been many fruitful applications, and many of them are not suitable for solvent-based epoxy resins.


At present, the application of waterborne epoxy resin mainly has several aspects: concrete sealing primer, industrial floor coating, wood paint, anticorrosive coating, waterproof material and anti-leakage material, cement mortar repair material, adhesive, glass fiber infiltrant, Anticorrosive primer for aluminum foil, paint for nuclear facilities, etc
