Highly-filled sealant compositions
A sealant composition comprising a binder and a filler material. The binder comprising a residual pitch product and an elastomeric material and, optionally, asphalt, a microcrystalline wax, and/or oil. The filler material is present in an amount of between about 11 vol. % and about 67 vol. % of the sealant composition. In one embodiment, the filler material is present in an amount of between about 25 wt. % and about 70 wt. % of the sealant composition.
1. A sealant composition comprising:
a binder comprising:
an asphalt;
a residual pitch product; and
an elastomeric material; and
a filler material in an amount of between about 11 vol. % and about 67 vol. % of the sealant composition, wherein the sealant composition is not an aqueous-based emulsion.
2. The sealant composition of claim 1 wherein the residual pitch product comprises tall oil pitch.
3. The sealant composition of claim 1 wherein the binder further comprises a microcrystalline wax.
4. The sealant composition of claim 3 wherein the binder further comprises an oil.
5. The sealant composition of claim 1 wherein the elastomeric material comprises rubber.
6. The sealant composition of claim 1 wherein the filler material comprises calcium carbonate.
7. The sealant composition of claim 1 wherein the residual pitch product is at least about 34 wt. % of the total weight of the binder.
8. The sealant composition of claim 1 wherein the filler material is present in an amount of between about 25 wt. % and about 70 wt. % of the sealant composition.
9. A sealant composition comprising:
a binder comprising:
an asphalt from the distillation of petroleum;
a residual pitch product; and
an elastomeric material; and
a filler material in an amount of between about 11 vol. % and about 67 vol. % of the sealant composition, wherein the sealant composition is not an aqueous-based emulsion.
10. A sealant composition comprising:
a binder comprising:
an asphalt having a softening point of between about 85° F. and about 200° F.;
a residual pitch product; and
an elastomeric material; and
a filler material in an amount of between about 11 vol. % and about 67 vol. % of the sealant composition, wherein the sealant composition is not an aqueous-based emulsion.
