Abstract
A water dispersible low-reflectance coating composition which is a CARC cosition and results in a coating that is flexible at ambient and sub-zero temperatures. The composition is a three component system, where the first component includes: hydroxyl-functional polyurethane, pigments, polymeric beads, emulsion of hydrophobic solids, micro-milled calcium carbonate, anti-settling agent, dispersing agent, water solvent, and non-ionic emulsion. The second component includes polyisocyanate and a solvent, while the third component is water solvent.
