ABSTRACT:
A low viscosity high solids thermosetting coating composition useful in the packaging industry as a barrier coating and overprint varnish, based urea-formaldehyde crosslinking agents and low molecular weight polyols, is provided. These compositions provide rapid cure response and afford coatings having good gloss, clarity, and mar resistance and are non-blocking. The compositions do not contain aromatic solvents and are applicable by gravure or flexographic techniques.
