Epotek OG116-31 is a single-component high Tg UV epoxy for rapid-cycle assembly of optical and microelectronic parts. It delivers strong, stable bonds in seconds.

Key Features of OG116-31 High Tg UV Epoxy

• High glass transition temperature
• Full strength in seconds under UV
• Perfect for lens bonding and glob top

Stable at High Temperatures

This high-solids adhesive has a very high glass transition temperature. As a result, optical alignments and structural bonds stay stable at elevated operating temperatures.

Cures in Seconds

OG116-31 reaches full strength in seconds under UV light. In addition, it becomes tack-free and highly resistant to chemicals and moisture.

Precise Application

Its low-viscosity, non-flowing rheology allows precise placement. So it stays out of keep-out zones and goes exactly where you need it.

Why Choose This High Tg UV Epoxy?

OG116-31 is a favourite in the fibre optic and semiconductor industries. For example, teams use it for lens bonding, glob top sealing and encapsulating sensitive sensors.

Therefore, it helps you boost throughput while meeting the strict quality standards of aerospace and telecommunications hardware.

Because it cures so fast, it also frees up fixtures and work-in-progress space. That makes it a strong fit for high-volume optical assembly.
