Aqueous polycatechol adhesives for artificial nail applications
Innovative, fast-acting aqueous polycatechol adhesives designed for bonding artificial nails to natural nails and skin, inspired by mussel adhesion principles. Offering strong, reversible bonding without external triggers, these adhesives are biocompatible and easy to apply.
Overview
Inspired by mussel adhesion, our aqueous polycatechol adhesives are a breakthrough in bonding artificial nails to natural nails and skin. These adhesives leverage biomimetic block polycatechols, formed from biocompatible polyethylene glycol, to provide fast-acting and robust adhesion. They offer strong bonding to diverse surfaces through spontaneous physical and chemical interactions without the need for external stimuli such as light or heat. The adhesive is reversible, making it easy to de-bond and clean after use, and is specifically engineered for applications in artificial nail adherence.
Technical specifications
