Abstract:
A waterborne pigmented liquid coating composition and method of making and using same which is substantially devoid of any surfactant dispersing and/or emulsifying agents thereby substantially eliminating flash-rusting upon application to ferrous substrates and improved resistance to deterioration on exposure to high moisture environments. The coating composition contains as its essential constituents one or a combination or mixture of substantially uniformly dispersed pigment particles, a film forming constituent comprising a mixture of substantially uniformly dispersed acrylic hydrosol particles and an aqueous soluble salt of a dispersant resin having acid functionality, and a liquid constituent comprising a mixture of water and organic solvents, the organic solvents functioning as coalescing agents for the film forming constituents.
