Compared with the commercial polymerization inhibitor PBQ and hs-905s, the DSC test, sheet storage time, sheet gelation time, sheet curing time and physical properties of sheet molding compound (SMC) products show that the polymerization inhibitor lx-6 has the highest DSC curve characteristic parameter temperature, the lowest exothermic enthalpy, the longest storage time and gelation time, and the shortest curing reaction time. The SMC products have the best physical properties, smooth surface and high brightness.展开更多
