Claim 0:
1. A urethane-based composition comprising:
a main composition part comprising an ester-based polyol resin;
a curing agent composition part comprising a polyisocyanate;
a filler; and
a moisture scavenger,
wherein the ester-based polyol resin is an amorphous polyol or a crystalline polyol,
wherein the amorphous polyol does not have a crystallization temperature (Tc) or a melting temperature (Tm) in a DSC (differential scanning calorimetry) analysis performed at a rate of 10° C./minute within a range of −80° C. to 60° C.,
wherein the crystalline polyol has a melting temperature (Tm) of −5° C. or lower,
wherein the filler is contained in an amount of 100 to 2,000 parts by weight relative to 100 parts by weight of the sum of the ester-based polyol resin and polyisocyanate,
wherein the curing agent composition part comprises the filler and the moisture scavenger, and
wherein the ester-based polyol resin is represented by the following formula 1 or 2:, wherein, X is a carboxylic acid-derived unit, Y is a polyol-derived unit, n is a number within a range of 2 to 10, and m is a number within a range of 1 to 10.
