Silicones With Optical Clarity

CHT’s series of optically clear silicones can be used to bond glass and plastics to flat screen panel and LCD displays and feature high refractive indices to provide contrast enhancement that yields high resolution. For LED encapsulation, these optically clear silicones feature non-yellowing catalyst systems providing UV resistance even throughout long-term exposure.

General Attributes:

• UV resistant - non yellowing
• Addition cure materials
• Low viscosities
• Choice of heat cure or heat accelerated RTV
• Working temperatures from -60°C to 200°C

Applications:

• LED potting
• Outdoor signage, display and lighting
• PV module manufacture
• PV concentrator cell manufacture
• Sealing aviation displays

CHT also manuafacture optically clear Liquid Silicone Rubber which can be used for various LED applications. One important area is the injection moulding of automotive headlamp light guides. For more information, see Silso Clear 21002 below or view the LED application page.
