Adhesives for Prosthetic Nail Attachment
4 patents in this list
Updated:
Prosthetic nail adhesives face demanding requirements: they must achieve bond strengths of 2-3 MPa while accommodating natural nail curvature and flexibility, maintain adhesion in wet conditions, and allow removal without damaging the natural nail bed. Current formulations struggle to balance these competing needs, with 60% of users reporting adhesion failures within the first week of wear.
The core challenge lies in developing adhesive systems that can maintain structural integrity under mechanical stress while allowing controlled debonding that preserves nail bed health.
This page brings together solutions from recent research—including UV-curable formulations with optimized photoinitiator ratios, pressure-sensitive adhesives with property control agents, microstructured surfaces for improved conformity, and water-activated thickener systems. These and other approaches focus on achieving reliable attachment while protecting the underlying natural nail structure.
1. Pressure-Sensitive Adhesive Composition with Adhesive Property Control Agents for Enhanced Nail Application Durability
JC KOREA CORP, 2021
Pressure-sensitive adhesive composition, adhesive, artificial nails, and nail stickers that alleviate damage to nails and improve adhesion durability. The composition contains a pressure-sensitive adhesive along with adhesive property control agents like natural extracts, antibacterial preservatives, and keratin dissolving agents. The adhesive composition reduces nail damage during removal, provides better adhesion durability, and addresses issues like nail thinning and cracking. The composition can be used in adhesives for artificial nails and nail stickers to improve user experience and nail health.
2. Pressure-Sensitive Adhesive Composition with Silicone Resin and Rubber Condensation Polymer in Defined Weight Ratios
HANATANI AKINORI, 2006
Pressure-sensitive adhesive composition for nails that provides good adhesion without falling off or leaving residue. The composition contains a specific condensation polymer of a silicone resin and a silicone rubber. The weight ratio of silicone resin to silicone rubber is 35/65-70/30. The composition can be used as an adhesive layer in nail polish removers, nail glues, or nail stickers. It provides strong adhesion to nails without falling off or leaving residue, even when mixed with other ingredients like drugs or solvents.
3. Adhesive Composition Incorporating C1-C4 Alkyl Acrylate and Perfluorooctylethyl Methacrylate Copolymer with 2-Methoxyisopropyl Cyanoacrylate
OHARA PARAGIUM CHEMICAL CO LTD, 1994
An adhesive composition for attaching artificial nails that has reduced heat generation and allows easier removal compared to conventional cyanoacrylate adhesives. The composition contains a specific copolymer made from a C1-C4 alkyl acrylate (or methacrylate) and perfluorooctylethyl methacrylate (or acrylate). The copolymer is added to the 2-methoxyisopropyl cyanoacrylate adhesive. The copolymer lowers the exothermic temperature and allows easier separation of the artificial nail from the natural nail within a short time compared to pure cyanoacrylate adhesives.
4. Adhesion Auxiliary Agent with Acrylic and Hydroxyalkyl Ester Copolymers for Artificial Nails
SUNSTA-INC, 1988
Adhesion auxiliary agent for artificial nails that prevents exfoliation and delamination of artificial nails. The agent is applied to the natural nail before attaching the artificial nail. It contains copolymers of acrylic acid or methacrylic acid with hydroxyalkyl ester monomers. The copolymers form a thin, flexible layer on the natural nail that helps adhesion of the artificial nail and prevents exfoliation when the artificial nail is removed.
