Beschreibung
Zusammenfassung:	The present invention relates to polyurethane polyol compositions comprising the reaction product of a polyisocyanate, a polyol, and a Guerbet alcohol having at least (12) carbon atoms or a Guerbet alcohol mixture having an average of at least (12) carbon atoms. Preferred polyols are alpha , beta diols and alpha , gamma diols. The polyurethane polyol compositions exhibit very low viscosity and are particularly useful in very low VOC coating compositions. The resulting cured coating provides surprisingly improved properties.
