| 摘要 |
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.
