Epotek 353ND is a trusted fibre optic epoxy for demanding optical and sensor work. It keeps performing under high-power laser and thermal stress.

Key Features of Epotek 353ND Fibre Optic Epoxy

• 800nm to 1600nm transmission
• Colour-change cure indicator
• Perfect for ferrules and fibre bundling

Clear Optical Performance

353ND offers excellent transmission from 800nm to 1600nm. As a result, it suits high-performance optical links.

See When It Is Cured

A colour-change indicator shows when the cure is complete. The epoxy turns from clear amber to deep reddish-brown. So you can verify joint integrity at a glance.

Strong and Resistant

It offers high mechanical strength and excellent resistance to moisture and chemicals. Therefore, it is a leading choice for bundling optical fibres, bonding ferrules and sealing semiconductor sensors.

Practical to Process

353ND gives a 3-hour pot life. In addition, it heat cures fast, in just 1 minute at 150°C.

Why Choose This Fibre Optic Epoxy?

For example, it serves aerospace communications and medical lasers. It gives the reliability that advanced data-communication and medical technologies demand.

Because the cure is so quick, it also helps you keep fibre termination lines moving. Meanwhile, the 3-hour pot life gives operators plenty of time to prepare and assemble each batch.
