Dymax Ultra Light-Weld 3069 Flexible Laminating And Bonding Material 30Ml Syringe (Pack Of 10)
Dymax Ultra Light-Weld 3069 Flexible Laminating And Bonding Material 30Ml Syringe (Pack Of 10)
Dymax Ultra Light-Weld® 3069 is a UV-cure adhesive designed for rapid bonding and laminating of both flexible and rigid substrates, including PVC, polycarbonate, polyurethane, PET, PETG, and ABS. Bond strength on polycarbonate and PVC typically exceeds the strength of the substrate itself. The cured adhesive remains flexible, making it well-suited for applications involving flexible lamination, plastic housing assembly, appliance assembly, and speaker assembly where rigid bonds would crack or delaminate under stress. Lead time is 1–2 weeks. Sold in packs of 10 x 30mL syringes.
Sold in packs of 10 syringes (30mL each).

Frequently Asked Questions
What substrates is Ultra Light-Weld 3069 designed to bond?
Ultra Light-Weld 3069 is formulated for bonding and laminating PVC, polycarbonate (PC), polyurethane, PET, PETG, and ABS. Bond strength on polycarbonate and PVC typically exceeds the strength of the substrate itself, meaning the substrate will fail before the adhesive bond. For substrates not listed here, contact MTE Solutions or Dymax for compatibility testing guidance.
Why is a flexible adhesive important for lamination applications?
Rigid adhesives can crack or cause delamination when bonded assemblies flex, vibrate, or experience thermal cycling. Ultra Light-Weld 3069's flexible cure allows the bond line to move with the assembly, maintaining adhesion integrity in applications like flexible film lamination, speaker assembly, and plastic housing assembly where the bonded parts are subject to ongoing stress or movement.
How is Ultra Light-Weld 3069 cured?
Ultra Light-Weld 3069 is cured using UV/Visible light and cures in seconds upon exposure. Dymax UV curing lamps and spot cure systems are recommended for consistent, validated cure cycles. Cure time and intensity depend on the lamp output, distance, and adhesive thickness. Contact MTE Solutions for guidance on compatible Dymax UV curing equipment if needed.
What is the difference between the 30mL and 10mL syringe options?
Both contain the same Ultra Light-Weld 3069 formulation. The 30mL syringe is better suited for higher-volume production runs or applications requiring larger deposits, while the 10mL syringe is preferred for lower-volume work, R&D, or applications where minimizing material waste between changeovers is important. Both are sold in packs of 10 syringes.
What is the shelf life of Ultra Light-Weld 3069?
Shelf life is 18 months from the date of manufacture when stored between 10°C (50°F) and 32°C (90°F) in the original unopened container. Store the material in a cool, dark place and keep it covered when not in use, since the product may polymerize upon prolonged exposure to ambient and artificial light.
Does Ultra Light-Weld 3069 contain solvents?
No. Dymax materials contain no nonreactive solvents and cure upon exposure to light. Their ability to cure in seconds enables faster processing, greater output, and lower processing costs, and the product is in full compliance with RoHS directives 2015/863/EU.
