Popis: To obtain sealants with high heat resistance based on epoxy resin, the latter has been modified using tris-(p-isocyanatophenyl)thiophosphate and SKTN-A rubber dimethylsiloxane. Cyclic amine has served as a structuring agent. Products of the modification have been studied by spectral methods. Their physicomechanical and rheokinetic characteristics, as well as relaxation properties, have been determined. It is shown that an increase in heat resistance, glass transition temperature, and water resistance is achieved with the introduction of silicone rubber in an amount of 10 wt parts or more in the epoxyurethane system.
