Permabond UV006490001L0101, UV649 UV-Curable Adhesive, 1 Liter Bottle
Permabond UV006490001L0101 UV649 UV-Curable Adhesive, 1 Liter Bottle
Permabond UV649 is a single-part, fast-setting UV-curable adhesive designed for bonding plastics, metals, and glass, with excellent adhesion to polycarbonate and a wide range of other plastic substrates. UV649 delivers very high shear strength, elongation, and impact resistance — making it well suited for assemblies involving dissimilar materials or substrates with different coefficients of thermal expansion. Good depth-of-cure capability makes UV649 effective as a sealant in addition to a structural adhesive. The 1 liter bottle is suited for high-volume production and automated dispensing.
Sold individually (1 liter bottle).

Frequently Asked Questions
How does UV649 compare to UV645 and UV648?
UV649, UV645, and UV648 all bond plastics, metals, and glass with high shear strength, elongation, and impact resistance, and all have good depth-of-cure capability for sealing applications. The differences between these grades relate to viscosity and specific cure characteristics — consult the individual Technical Data Sheets or contact us to determine which grade best matches your application’s viscosity, cure speed, and substrate requirements.
Can UV649 be used as a sealant?
Yes. UV649’s good depth-of-cure capability makes it suitable for sealing applications in addition to structural bonding. This makes it a practical choice when a single adhesive needs to both bond and seal a joint, reducing the number of materials needed in an assembly process.
Why is UV649 recommended for dissimilar materials with different coefficients of thermal expansion?
When two materials expand and contract at different rates during thermal cycling, a rigid adhesive bond will experience stress at the bond line and can crack or delaminate over time. UV649’s high elongation allows the cured bond to flex and accommodate this differential movement, maintaining bond integrity through repeated thermal cycles — critical for electronics assemblies, outdoor applications, and any assembly exposed to temperature variation.
When should I choose the 1 liter bottle over the 50ml bottle?
The 1 liter bottle is designed for high-volume production and automated dispensing where smaller bottles would require frequent changeover. The 50ml bottle (UV006490050T0101, case of 10) is better suited for bench-level assembly, prototyping, or lower-volume applications where smaller quantities minimize waste.
