1. A resin composition comprising a main resin and a curing agent,
wherein the main resin comprises a polyol resin comprising an ester polyol resin, the curing agent comprises a polyisocyanate, and at least one of the main resin or the curing agent comprises a filler in an amount of 100 parts by weight to 2,000 parts by weight relative to 100 parts by weight of the sum of the polyol resin and the polyisocyanate, and
wherein the resin composition satisfies Equations 1 and 2:
10≤initial load value(Li)≤40  [Equation 1]
1≤load change rate(Lf/Li)≤3  [Equation 2]
wherein, Li is an initial load value (kgf) measured immediately after the main resin and the curing agent are mixed and Lf is an aging load value (kgf) measured at 3 minutes after the main resin and the curing agent are mixed.
