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.
