Abstract
The sealing material composition of the present disclosure includes a lactone-based compound having at least two functional groups A represented by the Chemical Formula (1) and a curing agent that is thermally reactive with the lactone-based compound and contains a compound having at least two of one or more kinds of functional groups B selected from the group consisting of a mercaptan group, a hydroxyl group, and a secondary amine group where, a is an integer of 0 or 1, and * is an atomic bond.
Claims6
A sealing material composition comprising:
- a lactone-based compound comprising a molecular chain represented by one of Chemical Formulas (2-1) to (2-8), the molecular chain having, at each of both ends thereof, a functional group A represented by Chemical Formula (1);
- and
- a curing agent being thermally reactive with the lactone-based compound and comprising a compound comprising at least two of one or more kinds of functional groups B selected from the group consisting of a mercaptan group, a hydroxyl group, and a secondary amine group,
- in Chemical Formula (1), a is an integer of 0 or 1, and * is an atomic bond,
- wherein the lactone-based compound comprises an enol lactone-based compound for which a in Formula (1) is 0,
