Abstract
High solids alkyd resin coatings are prepared by reacting at least a portion of the available hydroxyl groups on a resin with an ethylenically unsaturated monoisocyanate monomer. The new products, useful both as the major vehicle resin in high solids coatings and as a cure modifier for oxidatively curable alkyd, polyester and acrylic resins, impart improved drying and weathering properties to coatings while maintaining low paint viscosity.
