Claims16
A urethane-based composition comprising:
- a main composition part comprising an ester-based polyol resin;
- a curing agent composition part comprising a non-aromatic polyisocyanate;
- and
- a filler,
- wherein the ester-based polyol resin comprised in the urethane-based composition consists of an ester-based polyol resin having a viscosity of 2,000 cP or less at room temperature,
- wherein the ester-based polyol resin is an amorphous polyol, in which a crystallization temperature (Tc) and a melting temperature (Tm) are not observed in a DSC (differential scanning calorimetry) analysis, or has a melting temperature (Tm) of less than 15° C.,
- wherein the filler is comprised in an amount of 50 to 2,000 parts by weight relative to 100 parts by weight of the sum of the ester-based polyol resin and the polyisocyanate contents,
- wherein a mixture of the ester-based polyol resin and polyisocyanate has a glass transition temperature (Tg) of less than 0° C. after curing, and
- wherein the urethane-based composition is a two-component room temperature curable composition formulated to be able to be cured when the main composition part and the curing agent composition are mixed at room temperature.
