UV-Curable Nail Coatings via Segmented Thermoset Lattice
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional nail coatings either lack the durability and scratch resistance of thermoset artificial nails or are difficult to remove, requiring prolonged solvent exposure and abrasive methods, while nail polishes offer ease of removal but lack adhesion and durability.
Innovation Solution
A 3-D thermoset lattice interdispersed within a network of an organic solvent-dissolvable resin provides enhanced adhesion, durability, and scratch resistance while allowing for easy solvent removal, using a polymerizable composition comprising monomers, oligomers, and polymers that form a polymerized structure sensitive to solvents, facilitating quick and gentle removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional thermoset artificial nails are used, then adhesion and durability are improved, but removal becomes difficult requiring prolonged solvent exposure and abrasive methods
Solution Approach 1:
The nail coating system is segmented into two distinct functional layers: a thermoset lattice layer that provides durability and adhesion, and a separate organic solvent-dissolvable resin layer that enables easy removal. This segmentation allows each layer to independently fulfill its specific function without compromising the other.
Solution Approach 2:
The invention creates a composite material system combining thermoset polymers (for durability) with organic solvent-dissolvable resins (for easy removal). This composite structure integrates the beneficial properties of both material types, achieving both strong adhesion and simple removal capabilities in a single coating system.
2Ease of operation
If conventional nail polishes are used, then ease of removal is improved, but adhesion and durability deteriorate
Solution Approach 1:
The nail coating system is segmented into two distinct functional layers: a thermoset lattice layer that provides durability and adhesion, and a separate organic solvent-dissolvable resin layer that enables easy removal. This segmentation allows each layer to independently fulfill its specific function without compromising the other.
Solution Approach 2:

This composite structure integrates the beneficial properties of both material types, achieving both strong adhesion and simple removal capabilities in a single coating system.
3Strength
If conventional thermoset artificial nails are used, then scratch resistance is improved, but removal time increases from seconds to 30-90 minutes
Solution Approach 1:
The nail coating system is segmented into two distinct functional layers: a thermoset lattice layer that provides durability and adhesion, and a separate organic solvent-dissolvable resin layer that enables easy removal. This segmentation allows each layer to independently fulfill its specific function without compromising the other.
Solution Approach 2:
The organic solvent-dissolvable resin layer acts as a sacrificial component that can be quickly discarded through solvent application, while the underlying thermoset lattice layer remains intact on the nail. This allows the durable coating to be removed on demand without damaging the natural nail.
