Uses and methods:
DOPO can be used as an additive or reactive flame retardant mainly for the flame retardancy of epoxy resins. At the same time, it is widely used for flame retardancy of materials such as electronic device plastics, copper lining laminates, circuit boards, etc. It can also be used for flame retardancy treatment of various molecular materials such as linear polyester, polyamide, epoxy resin, polyurethane, etc. In addition, it can also be used as an optical material and soldering flux.
