Product Introduction of Momentive INVISISIL OP2131SD UV-cure Silicone
Momentive INVISISIL OP2131SD UV-cure Silicone is a UV-cure optical bonding silicone specifically designed for the interlayer of displays and touch-screen modules. This advanced silicone enhances high light transmittance and helps reduce surface glare, ensuring that displays and touch-screen units are easily readable in sunlight or bright indoor environments. In addition to improving visual clarity, INVISISIL OP2131SD helps protect touch screens and displays against thermal shock and physical impact.
Key Features
- Formulated as a UV-cure optical bonding silicone for efficient processing.
- Enhances high light transmittance to maximize screen visibility.
- Reduces surface glare, making screens readable in bright sunlight or indoor lighting.
- Provides critical protection against thermal shock and physical impact.
- Cures into a highly transparent rubber with an exceptionally low haze of 0.2%.
- Maintains optical clarity with a very low Yellowness Index (YI) of 0.4.
- Delivers reliable electrical insulation with a dielectric strength of 18 kV/mm.
Key Applications
- Interlayer optical bonding for touch-screen modules.
- Optical bonding for automotive displays.
- Optical bonding for consumer displays.
