Abstract
The possibility of regulating the curing rate and the complex of adhesive and deformation-strength properties of adhesive materials based on diphenylolpropane thioglycidyl ether (thiirane) has been studied as depending on the chemical nature of amine hardeners, as well as on the composition and ratio of components in curing agents based on their mixtures. The following have been used as initial hardeners: diethylenetriamine of the DETA brand, diethylenetriaminomethylphenol of the UP-583 brand, and aminopolyamide of the PO-300 brand. The ratio of the components of the mixed hardener has been selected to provide the best complex of adhesive and deformation-strength properties. It has been shown that, at the initial stage of curing, the compositions containing the mixed hardener significantly exceed the compositions cured by individual components of the mixture in terms of cohesive strength.
