FIELD: personal demand items.
SUBSTANCE: intended for use in production of carpets. Polyurethane bases of carpet coatings are produced with application of polyurethane-forming composition, where polyurethane is a product of interaction of polyisocyanate component and polyol component, containing mixture of isocyanate reaction materials, from which one or more of unnecessarily alkoxylated hydroxymethyl-containing (polyester) polyols make 25-90 wt %.
EFFECT: formula provides for considerable replacement of traditional polyols with polyols produced from yearly renewable energy sources, with preservation of important properties, like edge curling, strength of bundle fixation, viscosity and proper hardening rates.
