A polyurethane foam-forming reaction mixture composition including: (I) an organic isocyanate; and (II) an admixture of: (a) at least one autocatalytic polyol; (b) at least one ethylene oxide (EO)-capped polyol; (c) at least one reactive blowing catalyst; (d) at least one surfactant; and (e) water; and a polyurethane foam prepared from the above polyurethane foam-forming reaction mixture composition.

Polyurethane foam system

The present invention discloses polyurethane dispersions based on aliphatic isocyanates which form hard coatings wherein the coatings also have good solvent resistant properties. The enhanced properties of the coatings are achieved by including from 1 to 8 weight percent of a high functional polyol in the polyol formulation for producing the dispersions.
