  • 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.

  • Publication number: 20120253001
    Abstract: Insulated glass units are sealed with polyurethane made using a natural oil-based polyol (NOBP). In one embodiment the NOBP is made using a monol-rich monomer containing high levels of mono-hydroxy functional fatty acid methyl esters. Insulated glass sealants based on these compounds provide enhanced resistance to UV and oxidative degradation as compared to conventional products while still providing the required barrier and mechanical properties.

  • Publication number: 20110015292
    Abstract: A prepolymer and products made from the preopolymer is described. The prepolymer includes the reaction product of at least one isocyanate and at least one natural oil based polyol. The natural oil based polyol includes at least two natural oil moieties separated by a molecular structure having an average of at least about 19 ether groups between any 2 of the natural oil moieties or by a polyether molecular structure having an equivalent weight of at least about 480.

  • Publication number: 20090012230
    Abstract: The instant invention is a sealant composition comprising an ultra-high solid polyurethane dispersion comprising. The ultra-high solid polyurethane dispersion comprises (1) a first component comprising a first polyurethane prepolymer or a first polyurethane prepolymer emulsion, (2) a second component comprising a media phase selected from the group consisting of a second polyurethane prepolymer emulsion, a low solid content polyurethane dispersion, a seed latex, and combinations thereof; and (3) a chain extender. The ultra-high solid polyurethane dispersion has at least a solid content of at least 65 percent by weight of solid content, based on the total weight of the ultra-high solid polyurethane dispersion, and a viscosity of less than 5000 cps at 20 rpm at 21° C. using spindle #4 with Brookfield viscometer.
