INVISISIL™ Silicones
INVISISIL optically clear silicones offer both the optical clarity and protection required by advanced optical applications, including LED lighting materials. Delivering high optical stability and light transmittance, INVISISIL products can also contribute to the durability and reliability of devices through their long-term resistance to yellowing or delamination. Additionally, Momentive scientists continue to deliver enhancements in processability, with a broad selection of stable viscosities, as well as our patented Snap Cure systems for rapid, straightforward curing.
Shown to perform effectively and reliably even in harsh environments, INVISISIL optical materials, such as display optical bonding, OLED encapsulants, potting silicones and LED solutions are helping to improve customer experience and extend product life. INVISISIL silicones are typically able to improve light transmission and reduce surface reflection – which generally translates to better readability in sunlight and bright ambient light.
INVISISIL silicones can help shield electronics from the thermal shock of on-off cycling and reduce structure stress. Testing under prolonged heat exposure has shown an INVISISIL LED encapsulant to maintain non-yellowing light transmittance more effectively than the LED-grade epoxy substrate to which it was bonded. Tests have also indicated excellent UV stability and enduring transparency performance. As a passivation layer, INVISISIL silicone encapsulants can also help protect electronics against moisture, chemical agents and physical impact.
Offering high purity, low viscosity, low volatile outgas, and mild thermal cure, INVISISIL silicones are helping customers to achieve process simplicity. Our recently introduced INVISISIL Snap Cure systems can further aide with processing by curing rapidly at room temperature without the need for UV exposure. This can help to eliminate the problem of shadow cure, while enabling users to rework materials for up to two days, as well as mitigate problems caused by CTE mismatch. Furthermore, with typical shrinkage of less than 0.5% during cure, INVISISIL Snap Cure systems can help reduce the occurrence of thin panel warpage and subsequent "mura" defects.
INVISISIL solutions are also aiding our customers' sustainability efforts by providing protection to low energy consumption LED packaging from harsh environments, while maintaining optical performance for an extended lifetime. The Momentive INVISISIL optically clear silicone brand family is enabling our customers to create innovative solutions to engineering and production challenges in the LED, photonics, automotive, medical, aerospace and electronics industries.
