Polyurethane polyols and high solids coatings therefrom.

摘要

A polyurethane polyol is provided, which comprises the reaction product of a particular isocyanate component and a particular diol component in a specified ratio, which polyol component is selected from substantially monomeric, diols wherein the hydroxyl groups are seperated by 3 carbon atoms or less. Such polyurethane polyols possess a desirable spectrum of molecular weight properties, making them especially suitable for use in formulating high solids, high performance coatings.
