Claims
- 1. A low VOC ultra high solids thermosetting coating composition comprising:
- a polymeric component which comprises a polymer and a reactive diluent, said polymer resulting from polymerization in the presence of said reactive diluent of a monomer mixture comprising in the range of from 5 weight percent to 45 weight percent of at least one active hydrogen containing monomer, said weight percentages being based on the total weight of polymeric component solids and said polymer having a GPC weight average molecular weight varying in the range of from 3,000 to 12,000; and
- an isocyanate crosslinking component wherein the ratio of active hydrogen reactive groups on said isocyanate crosslinking component to active hydrogen groups on said polymeric component varies in the range of from 1.0 to 1.4.
- 2. The thermosetting composition of claim 1 wherein the polymeric component comprises in the range of from 10 weight percent to 50 weight percent of said reactive diluent, all percentages being based on the total weight of the polymeric component.
- 3. The thermosetting composition of claim 1 wherein said the polymeric component further comprises a catalyst.
- 4. The thermosetting composition of claim 1 wherein said the polymeric component further comprises a solvent.
