USG169 is a water clear optically transparent epoxy adhesive / potting compound for L.E.D. encapsulating, fiber optics, clear potting, or any optical and electronic applications. After the two components are mixed, it can be cured at elevated temperature to form a transparent, colorless solid with strong bonding to various substrates such as metals, silicon, flip chip, BGA, ceramics, LTCC, Al, Cu, stainless steel, etc. It is formulated with anti-ultraviolet protecting to minimize yellowing over time. It also provides bubble free and glass smooth finish.

Special Features and Benefits
• Water clear and optical transparency
• High bonding strength
• Low bleeding, low volatile
• Low ionic content

Typical Applications
• Opto-Electronic Applications
• LED Glob-Top Encapsulating
• Semiconductor and Telecommunications
• Optical Lens and IR Lens
• Fiber Optical Potting or Sealing
• Lens and Prism Bonding
• Bonding or Potting of Medical Devices
• Adhesive for Endoscopes or Light Guides
• Structural Bonding or Potting

USG169 has a shelf life of at least 12 months when stored at ambient in the originally sealed container.

Processing Instruction

For the package in a container (not in a cartridge), to ensure homogeneity of the mixing, the two components must be stirred thoroughly. Any possible air bubbles due to the mixing processing can be removed by applying vacuum.

We recommend running preliminary tests to optimize conditions for the particular application. Comprehensive processing instructions can be obtained by contacting directly to

USG169 has a shelf life of at least 12 months when stored at ambient in the originally sealed container. The 'Best use before end' date of each batch appears on the product label. Storage beyond the date specified on the label does not necessarily mean that the product is no longer usable. In this case however, the properties required for the intended use must be checked for quality assurance reasons.
