A self-curing sealant composition comprising:
- at least one polymer selected from acrylic polymers, polyurethanes or polyureas, and silane-modified polymers,
- between about 35% and about 70% by weight, based on total weight of the composition, of a mineral filler, and
- at least one C4 to C8 alkyl terephthalate.
A method comprising applying a self-curing sealant composition to at least one location under conditions effective to cause the self-curing sealant composition to form a connecting bond between two or more objects, articles or bodies or to fill at least a portion of an opening, junction or other space in, on or between one or more objects, articles or bodies, wherein the self-curing sealant composition comprises:
- at least one polymer selected from acrylic polymers, polyurethanes or polyureas, and silane-modified polymers,
- between about 35% and about 70% by weight, based on total weight of the composition, of a mineral filler, and
- at least one C4 to C8 alkyl terephthalate.
A method of making a self-curing sealant composition, comprising combining at least the following components:
- at least one polymer selected from acrylic polymers, polyurethanes or polyureas, and silane-modified polymers,
- between about 35% and about 70% by weight, based on total weight of the composition, of a mineral filler, and
- at least one C4 to C8 alkyl terephthalate.
