Permabond UV006490050T0101, UV649 UV-Curable Adhesive, 50ml Bottle, Case of 10
Permabond UV006490050T0101 UV649 UV-Curable Adhesive, 50ml Bottle, Case of 10
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. Consult the Technical Data Sheet to confirm viscosity and specific cure parameters versus related grades UV645 and UV648. The 50ml bottle is ideal for bench-level assembly and prototyping.
Sold in cases of 10 x 50ml bottles.

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.
What UV light source is required to cure UV649?
UV649 cures on exposure to UV light in the appropriate wavelength range. Cure time depends on UV intensity, wavelength, and bond line or sealant bead thickness. Consult the Technical Data Sheet for specific cure parameters for your application.
