The active toughening agent of epoxy resins is a kind of oligomers with various active end groups and various effects such as toughing, diluting etc. It can be widely applied to the manufacture of coatings, adhesive agents, packing materials, casting materials, soaking materials, as well as the manufacture of glass steel, carbon fiber compound materials, basic resin etc. It has very good using effects and convenient using process.
Its varieties are as follows: :
I. Active Polyether
