Abstract (en)
A release coating is applied to a paper web or other woven or non-woven substrate in the form of a foam. A foamed saturant can also be applied to the paper web or other substrate followed by the application of a foamed or unfoamed release coating composition to the paper web, without an intermediate drying step between the application of the foamed saturant, and the application of the release coating.
