Aspects described herein generally describe epoxy resins and methods of epoxy resin formation. In some embodiments, a resin includes the reaction product of one or more polythiols, one or more polyepoxides, one or more fillers and one or more amine catalysts. Polythiols have between two and about ten thiol moieties. Polyepoxides have between two and about ten epoxy moieties. One or more amine catalysts of the formula NR1R2R3, wherein each of R1, R2, and R3 is independently linear or branched C1-20 alkyl or two or more of R1, R2, and R3 combine to form cycloalkyl. The resin has a compressive strength of at least 14 ksi at 2% offset at 70°F and at least 8 ksi at 2% offset at 190°F.
