Disadvantages: high brittleness, poor weather resistance and aging resistance, flammable. If it is directly used in reinforcement engineering, it will cause great creep and creep, and its long-term performance will be unstable.
Considering the characteristics of reinforcement engineering (strong adhesion, durability, aging resistance and fire resistance, etc.). ), it is necessary to make use of the advantages of epoxy resin and avoid its disadvantages, so it is necessary to modify epoxy resin. That is to change its shortcomings. This problem is solved by adding various additives. From the content and acceptance standard of the code (GB50367), modified epoxy is mainly recommended. This is the mainstream.
Bonded steel and carbon fiber cloth glue, not involving vinyl, are both modified epoxy. www.njmkt.com/Products.asp
