Abstract
High functionality polyol compositions that have a low viscosity of less than 5,000 cks. at 130.degree. F. and an equivalent weight of at least 150 are useful for the formation of high performance coatings. These are produced by reacting a mixture of at least two polycaprolactone polyols having a hydroxyl number from about 180 to about 600 and a diepoxide.
Claims6
An adduct of a polycaprolactone polyol and a cycloaliphatic diepoxide comprising the reaction product of (a) at least two polycaprolactone polyols differing in average hydroxyl number by an amount from 250 to 400 and having average hydroxyl numbers from about 180 to about 600 and (b) a cycloaliphatic diepoxide, said adduct having a viscosity of less than 5,000 cks. at 130.degree. F. and an equivalent weight of at least 150.
