ABSTRACT:
A method for reducing the amount of microfoam in a spray-applied clear waterborne composition is provided, the clear waterborne composition including an emulsion-polymerized addition polymer bearing at least one first reactive group and a reactive modifier bearing one second reactive group and a water-soluble group, the second reactive group being reactive with the first reactive group; applying the composition to a substrate using a spray method; and drying the composition. A reduced amount of microfoam improves the clarity of a film of the composition. Also provided are monofunctional carbodiimide reactive modifiers and substrates bearing the spray-applied clear compositions.
