Abstract
A carpet backing composition that includes a frothable aqueous composition and a froth aid. The frothable aqueous composition includes a polymeric binder, and the froth aid includes a polypropylene glycol, a polypropylene glycol ether, or a combination thereof. The froth aid has a weight average molecular weight of 130 to 2000. The carpet backing composition can be used to prepare a carpet product.
Claims10
A carpet product prepared with a carpet backing composition where the carpet backing composition is present over a primary backing of the carpet product, the carpet backing composition, comprising:
- a frothable aqueous composition having 11% to 100% by weight of a polymeric binder and up to 89% by weight of an inorganic filler, based on a total weight of the polymeric binder and the inorganic filler;
- and
- a froth aid comprising a polypropylene glycol, a polypropylene glycol ether, or a combination thereof, where the froth aid has a weight average molecular weight of 130 to 2000.
A method of coating a carpet, comprising:
- frothing a frothable aqueous composition having a polymeric binder, an inorganic filler, and a froth aid, the froth aid comprising a polypropylene glycol, a polypropylene glycol ether, or a combination thereof to form a froth, where froth aid has a weight average molecular weight of 130 to 2000;
- and
- applying the froth to a primary backing of the carpet.
