Abstract: Acid-catalyzed condensation of alcohols with epichlorohydrin produced monoepoxide compounds, which are 2,3-epoxypropyl esters of cyclohexanol, benzyl alcohol and 2-ethoxyethanol. In terms of dilution ability, they surpass the widely used phenylglycidyl ether (EFG) and cresylglycidyl ether of the UP-616 brand. It is shown that the properties of composite materials depend both on the type of diluent and on the curing mode (without heating and with heat treatment at 120 °C). Some diluents contribute to an increase in the parameters of tensile strength and deformation at break, as well as the adhesive strength of adhesive joints during shear, others – the modulus of elasticity and adhesive strength at separation. At the same time, the best combination of properties is provided by 2,3-epoxypropyl ethers of cyclohexanol and 2-ethoxyethanol. The synthesized epoxy diluents are suitably used for the preparation of low viscosity epoxy compositions, in particular for the production of filler materials, solvent-free varnishes, flooring materials with an improved complex of deformation-strength and adhesion properties.

Keywords: epoxy composites, monoglycidyl diluents, epoxypropyl ethers of cyclohexanol, benzyl alcohol and 2-ethoxyethanol curing mode, deformation-strength and adhesive properties.
