ABSTRACT:
Solid epoxy resins having low melt viscosity and high softening points are prepared by partially reacting the aliphatic secondary hydroxyl groups with a monoisocyanate to form pendant urethane groups. These resins are particularly useful as binders in preparing high flow-out, non-sintering powder paints.
