What plastics does the Uni-Weld™ UV plastic bonder bond?

Uni-Weld™ UV plastic bonders are formulated for bonding polycarbonate (PC), acrylic (PMMA), ABS, PVC, and other common engineering plastics. Select grades also bond glass, metal, and ceramics to plastics for multi-substrate assemblies in electronics, medical, and optical applications.

What tensile strength does the UV plastic bonder achieve?

Uni-Weld™ UV plastic bonder grades achieve tensile bond strengths up to 10,800 PSI — significantly higher than standard adhesives used for plastic bonding. Ultra-low shrinkage formulations maintain dimensional stability and prevent stress cracking on sensitive optical and precision assemblies.

What UV wavelength is needed to cure Uni-Weld™ plastic bonder?

Uni-Weld™ plastic bonder grades cure in the 365–405 nm UVA range. Compatible curing equipment includes Incure UV LED spot lamps (L9000™), UV LED flood lamps (L-Series™), and UV cure chambers (B/C-Series™). Select grades also support visible light cure for opaque assemblies.

How do wicking grades differ from high-viscosity structural grades?

Wicking grades (as low as 100 cP) are ultra-low viscosity adhesives that penetrate assembled joints by capillary action — ideal for pre-assembled plastic parts, needle bonding, and microfluidic channel sealing. High-viscosity structural grades (up to 84,000 cP) are dispensed before assembly and used for gap-filling, potting, and load-bearing structural bonds.

Does UV plastic bonder work on optically clear assemblies?

Yes. Uni-Weld™ optical grades cure to a crystal-clear finish with no yellowing or optical distortion, making them suitable for lens bonding, display assembly, and optical component manufacturing where bond-line visibility must be minimised.
