  • Publication number: 20130177733
    Abstract: Disclosed are carpet products comprising at least one flexible substrate and at least one coating layer associated with the at least one flexible substrate. The coating layer is formed from an aqueous composition comprising: A) an emulsifier-stabilized vinyl acetate/ethylene (VAE) emulsion copolymer dispersion wherein the VAE copolymer therein comprises co-monomers which include at least vinyl acetate copolymerized with ethylene and optionally also with other additional functional and/or non-functional co-monomers; and B) at least one particulate filler material selected from particulate inorganic compounds and particulate plastic material. The vinyl acetate/ethylene copolymer in the copolymer dispersion has a particle size, dw, ranging from about 50 to about 500 nm as determined by Laser Aerosol Spectroscopy.

  • Publication number: 20130156997
    Abstract: Disclosed are carpet products comprising at least one flexible substrate and at least one coating and/or adhesive layer associated with the at least one flexible substrate. The coating and/or adhesive layer is formed from an aqueous composition comprising: A) an emulsifier-stabilized vinyl acetate/ethylene (VAE) emulsion copolymer dispersion and B) at least one particulate filler material selected from particulate inorganic compounds and particulate plastic material. The vinyl acetate/ethylene copolymer in the copolymer dispersion has a selected ethylene content or glass transition temperature. It is also preferably substantially free of cross-linkable co-monomer moieties which generate formaldehyde upon curing and preferably has a particle size, dw, ranging from about 50 to about 500 nm. The carpet product is substantially free of polyvinyl chloride and bitumen and exhibits a Class B1 flame-retardancy in accordance with DIN 4102-14, corresponding to a critical heat flux of ?about 4.5 kW/m2.
