New type of high temperature curing agent of epoxy resin F-51A, F52B
MODEL F-51A, F-52B NEW TYPE HIGH TEMP RESISTANT EPOXY SOLIDIFICATION AGENT
This series is a solidifying agent of hydroxybenzene base of high temp resistance, the A type, of 200 mesh, can be directly applied in epoxy resins and B type, of 100 mesh, can be solved in industrial alcohol to be prepared into alcohol solution of 45% concentration. The test result at 15~20MPa (room temp) shearing strength can be gained on the steel strip sample bound with epoxy glue prepared with the said solidifying agent, even it can reach 6~10MPa when it is at 300 oC and it still assumes optimistic strength in case the steel strip sample under 400oC/1h sudden cooling then down to room temperature. It can make epoxy-coating materials of HTR too, with the features of HTR and acid/alkaline resistance.
Model F solidifying agents and Model Epoxy E-51 at iso-weight ratio show the solidification substance’s decomposition temperature at approx 380 oC and remains 38% residual carbon at 800 oC.
When the customers have the epoxy resin solidified with F alcohol solution, the solidification method of 180oC/3h should be adopted.
