Abstract:
Disclosed are waterborne coating compositions that include: (a) a base-neutralized carboxylic acid functional polyacrylate; and (b) a hydrophilic polycarbodiimide, in which (a) and (b) are present in relative amounts such that a ratio of carbodiimide groups to carboxylic acid groups in the composition is greater than 0.2:1, and in which the composition is substantially free of isocyanate functionality. Also disclosed are methods of using such compositions to produce a dry-erase surface and kits that include such compositions.
