  • Patent number: 7148287
    Abstract: Compositions incorporating water-curable urethane constituent(s) are formulated with favorable viscosity and viscosity stability characteristics, while at the same time, preserving desired hardness characteristics. The present invention is particularly useful in applications in which water-curable compositions include NCO-functional resins having relatively high NCO content and/or incorporate MDI-based constituents. Preferred modes of practicing the invention include implementing one or more formulation strategies to help retain hardness while preserving good viscosity characteristics. These preferred strategies involve (i) balancing scavenger, polyisocyanate and polyfunctional polyol content of the compositions or resins thereof, as the case may be, (ii) formulating an NCO-functional resin with chain extender constituent(s) to enhance viscosity stability, (iii) formulating with one or more plasticizers that enhance viscosity performance, and (iv) combinations of two or more of these strategies.

  • Patent number: 7125950
    Abstract: A solvent-free process for making a polyol fatty acid polyester composition useful for preparation of polyurethanes is described. These compositions are preferably made by reaction of a natural oil (from plant or animal) with a multi-functional hydroxyl compound derived from a natural source, such as sorbitol, in presence of an alkali metal salt or base such as potassium hydroxide as a catalyst which also acts to saponify the reaction mixture. The hydroxyl content of the prepared composition depends on the amount of the multi-functional hydroxyl compound used in the preparation. In another embodiment, the hydroxyl groups of these compositions are reacted with an isocyanate, such as the polymeric diphenylmethane diisocyanate (also known as 4,4?-diphenyl methane diisocyanate, or MDI) to form polyurethanes in a conventional manner.
