ABSTRACT:
Low viscosity, high solids polyurethane coatings compositions are prepared from a diricinoleate derivate and an isocyanate or from a diricinoleate derivative, a high viscosity polyol, and an isocyanate. Also, a method for reducing the viscosity and increasing the solids content of a polyurethane coating by adding from about 1 to 99 percent by weight of a diricinoleate derivative to a hydroxyl bearing component before reacting with an isocyanate, and a method for preparing a polyurethane coating having a low viscosity suitable for spray coating applications by reacting a diricinoleate derivative with an isocyanate.
