Strippable aqueous emulsion inomeric coating for recyclable plastic containers

摘要

Strippable aqueous a ionomeric coating composition suitable for coating plastic substrates where the coatings are easily removable by caustic treatment of the plastic during recycling of the plastic. The strippable ionomeric coatings comprise 80% to 99.8% by weight carboxyl functional aqueous addition copolymer (latex) intermixed with zinc or zirconium ammonium complex, where the zinc or zirconium complex interact during curing to provide ionomeric crosslinking with the.
