ABSTRACT:
A process for improving the water vapor permeability of polyurethane coatings by incorporating a hydroxy alkyl amine, an alkoxylated amine or the salt of either with an inorganic or organic acid into the coating composition is taught. Coating compositions including this water vapor diffusion enhancing additive are also taught as is a process for coating water vapor permeable substrates.
