摘要：
Combinations of solubilized, covalently crosslinked, siloxy-containing polymers in a solvent system of a volatile hydrophobic (non-polar) liquid that is non-stinging to a user are excellent non-irritating liquid coating materials for forming films, which, after solvent evaporation, are water insoluble but water-vapor permeable and lightly adherent to surfaces such as skin and mucous membranes. The crosslinking content is greater than 1 weight % and can be as much as 16 weight %. In comparison to non-crosslinked polysiloxy films, or crosslinked films of 1 weight % or less, the enhanced crosslinked polysiloxy films, while continuing to be soluble in the solvent, have reduced tack and reduced adhesion to skin and can act as sacrificial coatings under strongly adherent pressure sensitive adhesives.
