Abstract

The article presents the results of studies of the effect of corrosion inhibitors of various chemical compositions on the time of crosslinking, the thermal effect and the structural formation of a polysulfide sealant in which they are included. The data on the dependence of the crosslinking rate of a polysulfide sealant with corrosion inhibitors on temperature and relative humidity are presented; the phase transitions and the change in the heat capacity of the sealant samples are determined; the microstructure of the sealant is investigated and its effect on the protective properties of the composition is described
