IDB-Phoretar-312 is a kind of halogen-free flame retardant curing agent. He solidified with epoxy resin, and through this reaction grafted the flame retardancy onto epoxy resin, so as to achieve the purpose of curing epoxy resin and improving the flame retardancy of epoxy resin.
In order to cure epoxy resin and improve the flame retardancy of epoxy resin, the usual way is to first use DOPO and other flame retardants to react with epoxy resin to get flame retardant epoxy resin, then use Phenol novolac or dicyandiamide (DICY) as curing agent.
However, the flame retardant epoxy resin prepared by this method tends to become brittle in wet environment, and the thermal properties of epoxy resin are reduced sharply. When mixed with other epoxy resins, the overall flame retardancy of the mixed epoxy resin decreased with the decrease of phosphorus content.
IDB-Phoretar-312 is a high technology and innovative product in the field of flame retardance epoxy resin preparation. He made good use of the flame retardancy to give the curing agent the way to make up the shortcomings of the above methods for the preparation of flame-retardant epoxy resin. It not only improves the flame retardancy of epoxy resin, but also improves the thermal properties of epoxy resin, reduces the moisture absorption rate, and can be used with many kinds of epoxy resins. It is not only ordinary epoxy resin, but also can be used with high-end epoxy resin.
