Optimax® optical adhesives 6435 and 6450 providing low shrinkage, high clarity, and strong adhesion for precision optical and display applications.

What are Optimax® optical UV adhesives?

Optimax® optical adhesives such as 6435 and 6450 provide low shrinkage, high clarity, and strong adhesion for precise optical applications where transparency and light transmission matter. These adhesives are essential in display bonding, lens assembly, sensor encapsulation, and optical module manufacturing.

What applications are they used for?

Lenses and fibre optics
Display panels and touch screens
Medical imaging devices
Precision optical instruments
Electronics display manufacturing
Automotive optical systems
Industrial imaging and sensors

How do 6435 and 6450 differ?

6435 — lower viscosity, rapid UV cure
6450 — high strength, optional multi-cure for shadowed areas

Can they cure in shadowed areas?

Yes, Optimax® UV cured optical grades support heat or activator dual cure to reach inaccessible bond lines.

What are the key performance benefits?

Excellent clarity, minimal yellowing, low outgassing, refractive index control, and dimensional stability for optical and display manufacturing.
