SINOMER UVU6290
(Difunctional Aliphatic Urethane Acrylate)
Ingredient:Aliphatic Urethane Diacrylate
Types : Difunctional aliphatic amino ester
Supply form: 100% Resin
Excellent Non-Yellowing Performance: Due to its aliphatic structure, it maintains color stability upon and after UV exposure.
Good Flexibility: Provides outstanding elasticity and crack resistance to the cured film.
High Water Resistance: Exhibits excellent resistance to boiling water, ensuring film integrity.
Superior Weatherability: Resists degradation from UV light and environmental factors.
Low Odor
Good Adhesion: Promotes strong adhesion to various substrates, including plastics (PC, etc.) and metal layers.
The polymerization inhibitor (MEHQ for example) can be controlled within 50ppm, which is suitable for skin contact areas such as nail polish.
