Single molecular weight low molecular weight epoxy resin (SLEEP) is a bisphenol A-type epoxy resin with zero polymerization degree (n=0). It is colorless and transparent, with a viscosity of only 4000-5000 mPa · s, which is only 1/3~1/4 of that of ordinary epoxy resin (E 51). Therefore, it is particularly suitable for certain application fields that do not want to use diluents, such as high-performance fiber winding composite materials, solvent-free insulation paints with high voltage resistance, and fields that require high optical properties or color. In addition, it can also be used as a monomer for synthesizing high relative molecular weight epoxy resins, with no by-products generated, no purification required, and a wide range of relative molecular weight adjustment.

The distillation temperature isepoxy resinAn important parameter in the distillation process，It will affect the yield and purity of the target product. Considering that high distillation temperature can easily cause material decomposition, although the higher the temperature, the higher the yield, at this time heavy molecules will enter light molecules, resulting in a decrease in the purity of the target product.
