ABSTRACT:
The present invention includes a bio-based carpet material that includes tufts, a backing, a pre-coat, and a backing material wherein the pre-coat includes the reaction product of a pre-coat A-side having a pre-coat isocyanate and a pre-coat B-side and the backing material includes the reaction product of a backing material A-side having a backing material B-side. The pre-coat B-side and the backing material B-side may include a polyol at least partially derived from petroleum, a vegetable oil, and/or a transesterified polyol and a cross-linker and a catalyst.
