Abstract
A class of alkanol amine ligands reacted with bismuth carboxylates lends unique curability properties to isocyanate and polyols for production of polyurethane for CASE applications, including growing demand for polyurethane spray-foam. The amino-alcohol ligand, when associated with bismuth neodecanoate, offers improved moisture and solvent resistance during B-side (polyol) storage, cure rates analogous to tin-based curatives, and overall good final physical properties of the cured polyurethane.
