Epotek OG198-54 and OG198-55 are high-performance, single-component UV curable adhesives. They are designed for precision bonding of optical fibres and lenses.

Key Features of Epotek OG198 UV Curable Adhesive

• Rapid UV cure
• Low internal stress
• Perfect for fibre optic bonding

Fast Cure, Low Stress

These adhesives cure rapidly under UV light while keeping internal stress low. As a result, they help prevent signal attenuation in fibre optic interconnects.

Two Grades for Different Needs

OG198-54 is optimised for standard optical bonding. In contrast, the OG198-55 variant has a slightly modified rheology and cure profile. This helps it suit more complex assembly geometries.

Strong, Stable Bonds

Both adhesives offer excellent moisture resistance. In addition, they bond well to glass, quartz and technical plastics.

Their high glass transition temperature keeps optical alignments stable, even through significant thermal changes.

Why Choose This UV Curable Adhesive?

The OG198 series is a leading choice for makers of high-speed telecommunications hardware. For example, it is also ideal for medical endoscopes that need rapid assembly and precise optical alignment.

Because it cures in seconds under UV light, it can also help shorten assembly times. That makes it a practical fit for both prototyping and production.
