Permabond UV006320002L0101, UV632 UV-Curable Adhesive, 2 Liter Bottle
Permabond UV006320002L0101 UV632 UV-Curable Adhesive, 2 Liter Bottle
Permabond UV632 is a UV-curing adhesive developed specifically for bonding plastics, with superb adhesion to acrylic and a long-wavelength photoinitiator that allows it to cure through UV-stabilized plastics — a critical capability when bonding UV-blocking or UV-filtering plastic substrates where standard UV adhesives cannot reach sufficient cure. UV632 also bonds glass, metals, and other materials, and cures to a colorless bond, making it ideal for applications where optical clarity and aesthetic appearance are essential. The 2 liter bottle delivers the highest volume per changeover, making it the most efficient option for high-throughput production and automated dispensing operations.
Sold individually (2 liter bottle).

Frequently Asked Questions
What makes UV632 different from UV630 for plastic bonding?
Both UV630 and UV632 are designed for plastic bonding, but UV632’s long-wavelength photoinitiator is its key differentiator — it allows the adhesive to cure through UV-stabilized plastics that block the shorter UV wavelengths required by standard UV adhesives. If your substrate contains UV stabilizers or UV absorbers (common in outdoor-grade acrylics and polycarbonates), UV632 is the correct choice. UV630 is better suited for standard plastics without UV-blocking additives.
What is a UV-stabilized plastic and why does it matter for UV adhesive selection?
UV-stabilized plastics contain additives that absorb or scatter UV light to prevent the plastic from yellowing or degrading under sunlight or UV exposure. These same additives block the UV light that standard UV adhesives need to cure, preventing full cure at the bond line. UV632’s long-wavelength photoinitiator is activated by longer UV wavelengths that can penetrate UV-stabilized substrates, enabling reliable cure even through UV-blocking materials.
Is UV632 suitable for optical and display applications?
Yes. UV632 cures to a colorless, optically clear bond with no yellowing, making it well suited for display cases, optical assemblies, acrylic signage, decorative glass and plastic, and any application where bond line visibility would be unacceptable.
When should I choose the 2 liter bottle over the 1 liter or 50ml options?
The 2 liter bottle offers the highest volume per changeover and the lowest per-unit cost, making it ideal for high-throughput production lines and automated dispensing systems with high UV632 consumption. The 1 liter bottle (UV006320001L0101) suits moderate-volume production, while the 50ml bottle (UV006320050B0101, case of 10) is best for bench-level assembly and prototyping.
