Hardenable mixture of epoxy resin material containing polyoxyalkylene dithiol and polyamine

PURPOSE: To form a hardenable mixture which provides a crosslinked product having increased flexibility and strong elasticity by blending a specific dithiol and polyamine in epoxy resin. CONSTITUTION: The subject hardenable mixture comprises (a) epoxy resin, (b) a dithiol represented by formula I or II. In formula I and II, R 1 is each independently a hydrogen atom or methyl group; (x) is an integer of 2-50; (y) is an integer of 1-30, and (c) a polyamine having at least two primary amino groups. As for the epoxy resin (a), polyglycidyl ether of polyhydric phenol, especially diglycidyl ether of bisphenol A is preferable. As for the mixing ratio of each component based on the sum of the component (a) to (c), 5-30 wt.%, especially 10-25 wt.%, of component (b) and 3-35 wt.%, especially 5-20 wt.%, of component (c) is preferable.
