ABSTRACT:
A method of coating an adhesive polymer comprising hot-melt coating a composition of a hydrophobic adhesive polymer and a transient polar processing aid onto a substrate is provided. In addition, a method of coating a hydrophobic adhesive polymer when contacted with a transient polar processing aid, and a hot-melt coatable adhesive composition are also provided. These methods provide clear, smooth, and foam-free coatings, that are also substantially free of high temperature, low temperature, and processing aid-induced coating defects.
