The self-curing sealant composition of claim 3 wherein the di(2-ethylhexyl) terephthalate, and the 2,2,4-trimethyl-1,3-pentanediol diisobutyrate are present in equal amounts. 5. The self-curing sealant composition of claim 1, wherein at least one polymer is a polyurethane or polyurea. 6. The self-curing sealant composition of claim 1, wherein at least one polymer is an acrylic polymer. 7. The self-curing sealant composition of claim 1, wherein at least one polymer is a silane-modified polymer. 8. The self-curing sealant composition of claim 1, wherein the C4 to C8 alkyl terephthalate is present at a weight percent of about 3% to about 25% based on the total weight of the sealant composition. 9. The self-curing sealant composition of claim 1, wherein the C4 to C8 alkyl terephthalate is present at a weight percent of about 15 to about 25% based on the total weight of the sealant composition. 10. The self-curing sealant composition of claim 1, wherein the C4 to C8 alkyl terephthalate is present at a weight percent of about 5 to about 15% based on the total weight of the sealant composition. 11. The self-curing sealant composition of claim 1, wherein the C4 to C8 alkyl terephthalate is present at a weight percent of about 40 to about 60% based on the total weight of the sealant composition. 12. The self-curing sealant composition of claim 1, wherein the composition further comprises di-isoheptyl phthalate, butyl benzyl phthalate, diethylene glycol dibenzoate, dipropylene glycol dibenzoate or triethylene glycol dibenzoate. 13. An article comprising the self-curing sealant composition of claim 1. 14. The article of claim 13, wherein the article comprises two or more members and the self-curing sealant composition is disposed at the junction of two or more members of the article. 15. The article of claim 13, wherein the article comprises an opening, seam, or space, and the self-curing sealant composition is disposed in the opening, seam, or space in a manner that is effective to fill the opening, seam, or space. 16. 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, andat least one C4 to C8 alkyl terephthalate. 17. The method of claim 16, wherein the at least one location is an opening located at the junction of two or more architectural members and the method comprises obstructing the opening. 18. The method of claim 16, wherein the opening, junction, or other space is a seam between the two or more architectural members, automotive parts, or components of an aircraft, or a watercraft. 19. 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, andat least one C4 to C8 alkyl terephthalate. 20.
