  • FLEXIBLE POLYURETHANE FOAM AND PROCESS TO MAKE
    Publication number: 20190375881
    Abstract: Disclosed is a composition and process for making a flexible polyurethane foam from a polyol mixture that contains a copolymer polyol, a polyether polyol having a functionality equal to or greater than 3, an autocatalytic polyol, a hydroxyalkyltriethylenediamine and/or a hydroxytriethylenediamine catalyst, and a tertiary amine catalyst. Said foams have excellent resiliency and low compression sets and are particularly suited for use in low emission automobile seating applications.

  • Polyurethane dispersions and coatings produced therefrom
    Patent number: 8362142
    Abstract: 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.
