    Abstract: Disclosed is a surface coating solution comprising: a water-based solution including polymer in an emulsion; and activated boehmite particles provided in the water-based solution, the boehmite particles comprising mainly anisotropically shaped particles having an aspect ratio of at least 3:1; wherein the surface coating solution has flow and levelling of at least 6; wherein the surface coating solution has a sag resistance greater than 7 mils. The activation of the boehmite particles may be achieved by formation of salts with surface nitrates located on the boehmite particles or adding amines. Ammonium hydroxide, alkali and alkali earth metal salts such as magnesium sulfate and calcium sulfate, thickening clays such as nanoclays, or colloidal silica may be added to activate the boehmite particles. Activation may be carried out by adding substrate particles having surface charge opposite that of the boehmite particles (e.g., colloidal silica is negatively charged, thereby interacting with positively charged boehmite particles).
