AIST: Solvent-free paint development: paint, coating agent, gel nail
New technology features:
Developed technology that mixes liquid crystal components with paint materials and controls adhesion with light
When exposed to near-ultraviolet light, the structure of the liquid crystal component changes and the adhesion of the coating material is greatly reduced.
Expected to be applied to gel nails and other paints and coatings that can be removed without using solvents
“AIST” / “TAT”
The “AIST” Smart Materials Group has jointly developed “TAT” with a technology to create paint materials that can be removed without using solvents.
This technology:
This time, we have created a new resin in which liquid crystal components are uniformly mixed in acrylic resin or urethane resin.
It was found that when this resin was irradiated with near-ultraviolet light having a specific wavelength, the aggregation structure of the liquid crystal components that were uniformly mixed was changed and phase-separated from the resin.
When this technology was applied to a coating material, the adhesion of the coating material was greatly reduced due to the phase separation of the liquid crystal component by near ultraviolet light.
In addition, it has been improved in hardness and colorless so that it can be applied to gel nails.
Conventional technology:
Until now, it was difficult to remove the coating material without using a solvent, which has been a long-standing problem.
On the other hand, the technology developed this time responds directly to such needs.
Application for gel nails:
In particular, when applied to gel nails, it can be easily removed without using a large amount of organic solvent.
It can be expected to improve the health and safety of gel nail users and manicurists.
