| Abstract: |
| The cured thermosets exhibit excellent properties such as good dimensional stability, rigidity, corrosion
resistance and wear resistance, which are widely used in aerospace, national defense military, electronic and electrical
field, as well as construction and transportation. Controllable viscosity adjustment serves as a crucial means to optimize
the processing and enhance the performance of the cured thermosetting resins. This paper reviews the research progress
in viscosity regulation of thermosetting resins, focusing on typical methods such as adding thickener, adding diluent,
resin modification, filler modification, copolymerization modification and adjusting the degree of pre-polymerization.
The change of viscosity of modified thermosets is also discussed, and the development trend of this process is
prospected |
