Phase Separation Driven On-Demand Debondable Waterborne Pressure-Sensitive Adhesives
A waterborne pressure-sensitive adhesive (PSA) that shows high adhesive performance and easy debondability on demand without leaving residues on the substrate (adhesive failure) has been developed. A key component of the PSA is a semicrystalline phase that is beneficial for the adhesive properties a...
