Claims

1. A coating composition comprising: (a.) an acrylic modified alkyd resin;(b.) a long oil alkyd;(c.) an chlorinated polyolefin modified acrylic;(d.) a volatile organic solvent;(e.) a drying agent; and(f.) a colorant.

2. The coating of claim 1 wherein the chlorinated polyolefin modified acrylic plus the acrylic modified alkyd and the long oil alkyd are present at a weight solids ratio between about 1 to 1.8 and about 1 to 1.

3. The coating of claim 1 wherein the acrylic modified alkyd plus the long oil alkyd and the chlorinated polyolefin modified acrylic are present at a weight solids ratio between about 4 to 1 and about 2 to 1.

4. The coating composition of claim 1 wherein the composition is substantially free of water.

5. A coating composition comprising: (a) about 30 to about 80 weight percent of a resin system comprising an acrylic modified alkyd resin, a long oil alkyd, and an chlorinated polyolefin modified acrylic resin;(b) a volatile organic solvent;(e) a drying agent; and(d) a colorant.

6. The coating composition of claim 5 wherein about 35% to about 40% of the total solids weight of the resin system is a long oil alkyd.

7. The coating composition of claim 5 wherein about 45% to about 50% of the total solids weight of the resin system is a long oil alkyd.

8. The coating composition of claim 5 wherein about 20% to about 25% of the total solids weight of the resin system is chlorinated polyolefin modified acrylic.

9. The coating composition of claim 5 wherein about 30% to about 35% of the total solids weight of the resin system is chlorinated polyolefin modified acrylic.

10. The coating composition of claim 5 wherein about 40% to about 45% of the total solids weight of the resin system is acrylic modified alkyd.

11. The coating composition of claim 5 wherein about 15% to about 20% of the total resin solids weight of the resin system is acrylic modified alkyd.

12. The coating composition of claim 5 wherein the paint product is substantially free of water.

13. A process of coating a substrate comprising: (i) providing a paint composition comprising about 30 to about 80 weight percent of a resin system comprising an acrylic modified alkyd resin, a long oil alkyd, and an chlorinated polyolefin modified acrylic resin, a volatile organic solvent, a drying agent, and a colorant;(ii) applying the paint composition to a surface;(iii) allowing the paint composition to cure or dry.
