The influence of the reactive diluents on properties of epoxy-thiokol adhesive compositions

The influence of mono- and diglycidyl diluents on the adhesion, deformation strength, and dynamic mechanical properties of the adhesive composition based on a product previously prepared by the thioetherification reaction between epoxy resin and liquid thiokol has been investigated. It has been shown that the introduction of the diluents into the composition leads to an increase in the tensile strength, failure strain, and the work of fracture of the material at a moderate change in the adhesion strength. The magnitude of the effect depends on the chemical nature of the diluent.
