FIELD: chemistry.
SUBSTANCE: invention relates to a curable sealing resin composition. The curable composition contains at least one anhydride-functionalised polymer in amount of 30-60 wt %, a polyol in amount of 10-25 wt %, an epoxide-functionalised polymer, oligomer or monomer in amount of 15-40 wt %, a urethane polyol-functionalised compound selected from a group consisting of urethane diol, polyurethane diol and combination thereof in amount of 5-15 wt % and a catalyst with respect to total weight of the resin. The resin composition can be cured at room temperature. Components used to prepare and cure the resin composition can be provided in form of two or more parts.
EFFECT: hydrolytic stability, high hardness, flexibility and low cost of production of the sealing resin which can be used to restore insulation and/or for environmental protection of cable joints, sealed articles etc.
